GREAT FUTURE PERSPECTIVES FOR PERENNIAL CULTIVATION
The Netherlands has a strong position in the cultivation of perennials, thanks to its fertile soil, advanced cultivation techniques, and a well-organised trade infrastructure. The industry contributes to ornamental horticulture, which is an important part of Dutch agricultural exports.
Dutch perennial cultivation is an important industry within the tree nursery industry, focusing on the cultivation of herbaceous plants that bloom year after year. These plants are used in gardens and are also an indispensable part of public green spaces. Dutch perennials are characterised by a large diversity; many different types of perennials are cultivated, including many native species. Moreover, Dutch perennials are known for their quality and health. And developments continue: Growers are working on developing new varieties and cultivation methods. There is also a growing focus on sustainable cultivation methods, and organic nurseries are on the rise.
International position
A large part of Dutch perennials is exported. Germany is a major buyer of Dutch ornamental horticulture products, as well as the United Kingdom and Belgium. Belgium and France are both producers and importers. The Dutch export position has slightly weakened in recent years, particularly in core countries such as the United
Perennials form the basis of the garden
Kingdom and France. Exports to the United States are influenced by various factors, including stricter phytosanitary requirements, transport costs, and competition from local growers. Additionally, geopolitical tensions and sustainability requirements play a role in trade dynamics.
Opportunities and threats
Perennial cultivation offers several opportunities, such as the growing demand for sustainable and native plant species. In addition, technological innovation offers opportunities to optimise production and strengthen the export position. However, there are also threats. Consider the consequences of stricter regulations, both in the Netherlands and for exports abroad. For instance, phytosanitary controls when exporting to the United Kingdom result in higher costs and more uncertainty. Moreover, climate change and extreme weather conditions are factors that could affect the availability of starting materials.
Dutch perennial cultivation remains an important player in the international
market. Despite the challenges mentioned above, this industry certainly has opportunities for further growth. Innovation is key, as well as strategic adjustments and investments.
Promotion of perennials
Good promotion is essential for sales. Many perennial plant growers are
collectively working on that through the promotional organisation Perennial Power. This initiative focuses on promoting perennials to consumers. Through targeted campaigns, inspiring content, and collaboration with growers and garden centres, Perennial Power increases the awareness and popularity of perennials among consumers. They organise promotional activities such as online campaigns and press materials for trade magazines and influencers. This encourages sustainable gardening and shows how versatile, colourful, and lowmaintenance perennials can be. Thanks to their efforts, perennials are gaining a more prominent position in gardens and in the hearts of garden lovers. Currently, 70 perennial growers are members of Perennial Power. Perennial growers who want to join this organisation can contact info@perennialpower.nl.
Vaste Plantenkwekerij Het Eyssel specialises in cultivation for the landscaping market
Vaste Plantenkwekerij Het Eyssel specialises in the cultivation of high-quality landscaping products. Its assortment now includes more than 1200 species and an annual production of 1.6 million plants. The nursery currently spans 5 hectares of container fields across two locations, the main site in Meerle and a secondary location in Meer. In addition to perennials, grasses, ferns, herbs, and ground covers are also grown. The company serves a wide range of customers: landscapers, green space providers, municipalities, wholesalers,

exporters, and garden centres. “By combining the strengths of two companies - Perennial Nursery Het Eyssel and Trading Nursery Het Eyssel - we can combine the expertise of a specialised nursery with the flexibility and service of a trading nursery,” says owner Maurice van Meel.
“Het Eyssel also aims to produce as sustainably as possible,” says Maurice. “We must be careful with nature, but in a realistic way. We are using fewer chemical products. And of course, we are MPS-ECAS certified. Especially in the changing climate conditions, we carefully consider which species to pot during which periods.” Het Eyssel is affiliated with MPS and is also a member of the promotional organisation Perennial Power.
Plantenkwekerij Plantsoen - from maintenance and landscaping to perennial cultivation Plantsoen in Hamont-Hachel (B) was founded in 2021 by owners Koen Kauffmann and Wim Freier as a business for garden maintenance and
landscaping. When the opportunity arose to take over an existing perennial nursery, they did not hesitate and focused 100% on cultivation.
The nursery specialises in perennials, ornamental grasses, and ferns. It primarily supplies garden centres, fellow growers, and wholesalers in the EU. Plantsoen has two locations with a total of 7000 m² of glasshouses, 2000 m² of tunnel greenhouses, and shading facilities. There is also a large container field of 3.5 hectares, which will be expanded, including an expansion of the assortment.
The KwekerBode spoke with Wim Freier and asked: “How do you make your nursery ecologically, organically, and biodiverse?” Freier: “Currently, we focus heavily on biostimulants to reduce the use of chemicals at the nursery. We are also testing peat reduction in our potting mix. Recaptured rainwater is used, and hedge edges are standard when establishing container fields and planting mother beds.” How does Wim Freier see the current situation of perennial cultivation? “We remain optimistic,” says
Freier. Nevertheless, macroeconomic conditions and peaks in climate remain something to watch out for. Drought was an issue for many nurseries. Freier: “We have good control over water supply on our container fields. Fortunately, we haven’t had issues with drought in recent weeks.”
In the near future, Wim Freier expects more focus on in-house propagation and mother plants, by setting up a separate department for this purpose.
De Gijzel Vasteplanten, strategically located in central Brabant
In 2024, Koen Schuurmans from Helvoirt took a bold step: he left his job in the tree nursery industry to start his own business in perennials. And that choice is proving to be more than fruitful. At just 29 years old, he now runs a small but rapidly growing nursery, specialising in the cultivation of perennials in P9 pots. Koen is no stranger to the industry. With experience as a cultivation worker and in the purchasing department within the tree nursery industry, he knew exactly where the opportunities were. The location of his nursery in Helvoirt - in the heart of North Brabant - plays a key role. “It’s an area where relatively few perennial growers are,” says Koen. “But it’s a place where customers looking for various nursery products frequently visit. They can now easily stop by for a beautiful assortment of perennials.” That smart insight is quickly paying off. In just the first season, Koen managed to plant and sell no less than 300,000 P9 plants. Currently, he is working on planting another 650,000 plants, which will allow him to offer his customers an even wider assortment. His nursery now has 1.2 hectares of container fields, which will eventually be fully utilised. The focus is on species that are widely applicable in public green spaces. “I am focusing on an assortment of about 350 species,” he explains. “That gives my customers
choice, while still keeping production manageable.” And Koen does most of the production himself. With help from a few temporary workers and motivated students, he is achieving impressive numbers. His goal for 2025? An annual production of 650,000 perennials in P9. An ambitious plan - but considering the flying start of his nursery, it’s only a matter of time before this goal becomes a reality.
Together with Koen, we also looked at the future: “The focus is now on optimal use of the existing container field and delivering high-quality plants and service,” he says. “From there, I will be looking at further expansion opportunities.” Climate change and drought make water an increasingly valuable resource. Koen is proactively responding to this. “This year we installed water catchment facilities, and we deliberately made them larger than required by the current regulations.” Despite stricter regulations and changing climate, Koen looks to the future of the industry with confidence. “Perennials are strong and fit well into modern green plans. There is increasing demand for biodiversity, low-maintenance planting, and perennials align perfectly with this. Especially in public green spaces, I see plenty of growth opportunities.”
The KwekersBode is of course curious about the reason for the company to participate in GrootGroenPlus. Koen Schuurmans: “Last year, GrootGroenPlus was a valuable introduction for me to introduce myself to potential customers. The event helped me make various connections, which formed a good foundation to start the season.
In the run-up to this year, I also visited several customers to get a better idea of their way of working and specific needs. Nevertheless, I find it efficient and valuable to meet both new and existing contacts in a short time. GrootGroenPlus offers the ideal platform for that.”

BIODIVERSITY IN SCANDINAVIA
In Scandinavian countries, the cultivation of trees, shrubs, conifers, perennials, and rose bushes play a crucial role in maintaining natural landscapes and biodiversity. The region is known for its unique balance between cold winters and mild summers, which made native plant species adjust to challenging circumstances. Thanks to age-old traditions in forestry and agriculture, growers continue to experiment with new cultivation methods.
The impact of climate change
Nevertheless, climate change presents a growing threat. Extreme weather conditions, such as unexpected frost and heavy rainfall, cause stress to the flora. Furthermore, the risk of invasive species increases, which negatively affects the health and biodiversity of native plants. At the same time, warmer temperatures offer opportunities to introduce new, adapted species. Scientific projects and nature conservation initiatives play an essential role in monitoring and supporting cultivation.
Innovative techniques such as controlled irrigation systems, reduced pesticide regimes, and the development of climate-resilient varieties are being employed to mitigate the negative effects of a changing climate. Through collaborations between governments, knowledge institutions, and the agricultural industry, a dynamic adaptation process is emerging. This enables the Scandinavian cultivation industry to preserve and even enrich its rich green heritage despite the increasing challenges posed by climate change.
Scandinavia as a market
Scandinavian countries form an extremely important market for tree nursery products. These countries also invest heavily in sustainable urban planning, recreational landscapes, and ecologically responsible management. They set high standards for the quality, sustainability, and climate resilience of the plants they receive, as they often face extreme weather conditions. This forces exporters to offer only
high-quality, climate-resilient varieties that can withstand long, cold winters and fluctuating summers. Companies like Heideveld BV have specialised in exporting to these markets. Thanks to close cooperation with selected growers, they can guarantee a wide range of products perfectly suited to the needs of garden centres, landscapers, and wholesalers in Scandinavia. In addition to a stable market, the Scandinavian countries promote innovation in product development and ecologically responsible cultivation methods. This continuous demand for advanced solutions ensures a steady flow of investment in research and development within the tree nursery industry.
In short, the Scandinavian market functions as a strategic engine for the export of tree nursery products, with its critical market needs driving the industry to continuously improve and
adapt to both ecological and economic developments.
Sweden
Sweden is not a large country when it comes to the nursery stock industry. The import value in 2023 was around 50 million euros, while the export value was about 6 million euros. “The industry is small in Sweden with few players. Many have disappeared. But we are an important industry that has a significant impact on people’s daily lives and, for example, on the ability to improve the climate in cities. Climate and environmental issues interest many young people; perhaps we can reach them through that avenue,” says Peter Welin. He is the chairman of the horticulture division of the Agricultural Federation, focusing on nursery products, and also runs one of Sweden’s largest plant nurseries, Essunga Plantskola. Sweden is a long and narrow country, almost 1600 kilometres long. Today, the country is divided into 7-8 plant zones, from 1 in the south to 7 in the far north. The variation in temperature and climate is considerable, but with global climate change, it is a challenge to predict what we can expect. This is also a much-discussed topic within the tree nursery industry.
Peter Welin: “We don’t know whether the differences in the country will become larger or smaller, but we also don’t know what the climate in countries that produce plant material for us will look like, and whether plants grown there will be usable here. We will need to reconsider plant choices for the climate, and there are currently many research projects on this topic.” To integrate the climate and sustainability goals, Welin believes the tree nursery industry must work better
with landscape architects, planners, and project managers. “It is a prerequisite to make this go as well as possible. When developing plant material, foresight is needed.”
The Danish garden plant industry is small, but high-quality
The garden plant industry in Denmark is a niche within the broader efficient and sustainable agricultural industry. Unfortunately, the exact figures on the production value of garden plants are limited. The agricultural industry accounts for about 22% of Denmark’s goods exports (including livestock, dairy, and grain). Within this industry, ornamental plants and horticultural products play a modest but steadily growing role, partly due to the increasing demand for sustainable and locally produced plants.
According to official figures, the export of garden plants amounts to 2.2 billion DKK. Garden plants are mainly exported to neighbouring countries such as Germany and Sweden, while imports mostly come from the Netherlands, which is a major supplier of young plants and seeds. Denmark positions itself as a leader in sustainable horticulture, with a strong focus on organic, climate-resistant plants. Through innovation, collaboration, and circular production methods, the country is addressing climate change and international competition. Danish growers invest in robust plant species, water conservation, and renewable energy. Denmark is also the world’s largest exporter of Christmas trees, with over 10 million units per year. Despite its small size, Denmark has big green ambitions.
Tree,
shrub, and perennial cultivation
in Norway
The Norwegian cultivation of trees, shrubs, and perennials is modest in size - with an estimated 40 tree nurseriesbut is steadily developing. The export is limited due to strict EU regulations, as Norway is considered a ‘third country,’ while imports primarily come from the Netherlands, Denmark, and Germany. “Not much is exported from Norway, it’s mostly imported from the EU,” says Maria Fall from the Norwegian Horticultural Association.
Opportunities lie in the growing demand for native plants with locally propagated material. However, this is complex: “The market wants the material to come from specific regions, but ‘specific’ is often anything but specific,” says Fall. The industry is also faced with challenges such as climate change and the increasing ban on non-native species.

Essunga Plantskola in Sweden
Still, there is also pride: plant health in Norway is considered among the best in the world. “We are happy with a strict phytosanitary regime,” emphasizes Fall. Growers work with environmentally friendly methods, limit invasive species, and follow strict import regulations to prevent diseases and pests.
An important step towards sustainability is the establishment of Plantinor SA, a cooperative where growers make agreements on production and distribution. “We are convinced that this is the way forward,” says Fall. “Export is good for the economy, but when it comes to sustainability, the goal must be to sell the majority of what you produce in your own country.”
The Norwegian tree and plant industry combines quality, collaboration, and environmental awareness and sees this as the key to sustainable growth for the future.
Challenges in Finland
In Finland, about 60 nurseries are active with a total area of 271 hectares. Most nurseries produce several plant groups, such as fruit plants, shrubs, and trees. The estimated production value is around 40 million euros, providing approximately 500 man-years of employment.
According to Hanna Tajakka, director of the Finnish Growers’ Organisation Taimistoviljelijät, the situation is relatively stable, “but the industry has faced challenges in recent years, such as a decline in housing construction and fewer infrastructure projects, although signs of recovery are now visible.”
The industry is mainly made up of small family businesses. Company successions remain difficult: “At best, 1-2 new companies are founded each year,” says Tajakka. At the same time, there is a growing shortage of young workers. The growers’ association is trying to engage young people with informational projects and school visits: “We want to encourage students to consider a career in nursery production.”
An emerging trend is the increasing demand for native plants, particularly from the public sector. This shift is aligned with themes such as biodiversity, nature-based solutions, and the prevention of invasive species. “Public opinion is shifting towards more natural gardening practices, which has led hobby gardeners to take a greater interest in native plants,” says Tajakka. However, the transition is challenging, partly due to the lack of suitable seeds and the establishment of sufficient production capacity.
Another bottleneck is the classification of some cultivated plants as invasive species. “Tree nurseries often receive this information too late, which means plants already in production cannot be sold anymore. This results in the loss of investments and additional removal costs,” warns Tajakka. The industry is therefore looking for better cooperation with authorities for a more predictable and workable phase-out process.
The Finnish tree nursery industry is thus at a crossroads of stability and renewal, with sustainability, native species, and labour rejuvenation being central themes for the future.
The basis for good cultivation is a healthy soil and healthy starting material at Liwardi Quick Hedging Liwardi Quick Hedging from Nispen finds its customers as far as Scandinavia. What attracts its customers to the company?
The KwekerBode spoke with Wouter Veraart. “The basis for good cultivation is healthy soil and healthy starting material. Most of our plant material is propagated and grown in-house. The plant material is then planted in the ground for 2 to 4 years. During this period, the plants are regularly pruned and undercut.” By applying soil measurements, we can fertilise location-specifically. This maintains the organic content and soil life. Cultivation tasks such as undercutting, fertilising, and weeding are performed by GPS-controlled machines
that have been developed in consultation with the machinery builder for Liwardi. This makes environmentally friendly and efficient working under good working conditions possible. Liwardi plants can be potted in containers of 5 to 30 litres. These containers are 100% recyclable and carbon-free. The potting soil used is specially formulated for the company. It contains starter phosphate for rapid root formation and sufficient nutrients to keep the plants in good shape for the first 5-6 months.
Most plants are supplied with a root ball. This can be done in various ways: by hand in jute or acrylic, while the larger plants (from 200 cm) can also be supplied in cardboard boxes. Delivering in these cardboard boxes has several advantages: less personnel is required for digging up, which leads to shorter delivery times. Plants can be planted with the box as it is fully biodegradableeven the adhesive used is starch-based and completely biodegradable. The box breaks down within 10 days in the ground and leaves no waste or remnants. The span is even slightly larger than with round/manual nets, resulting in even better regrowth. The box is equipped with convenient handles for easier handling during planting. The flat bottom of the box ensures the plants stand straight in the planting trench. When it comes to trade with Scandinavia, Wouter Veraart does not see much change. “If I look at the customers who place year-round orders, I don’t really see any growth or decline. The assortment that goes there is quite narrow due to winter hardiness.”
De Bloemenkampen specialises in large pot sizes
Founder Arnold van den Berg had a green thumb as a child. He grew various plants
in his father’s backyard. In 1991, together with his nephew, he founded the tree nursery De Bloemenkampen, named after the nature reserve where the tree nursery was established. De Bloemenkampen initially supplied to the Dutch market, but after 2000, when Van den Berg continued on his own, the company also started focusing on exports. Specialising in conifers in large pots (from 5 litres) was the next step. With this specialisation, De Bloemenkampen meets customer needs. After all, not everyone has the patience to grow the plants themselves. Moving to a larger location in Nunspeet in 2013 meant a complete transition from field cultivation to pot cultivation.
De Bloemenkampen focuses mainly on quality; the ambition is not to become the largest nursery in Europe but the best. This is evident from the use of good and modern materials and a tidy workplace. Additionally, the company focuses on sustainability; by inspiring and retaining their employees for the profession, but also, for example, through MPS certification.
De Bloemenkampen wants to work as sustainable as possible, says Herco van den Berg. “We are constantly adjusting to this in several respects: environment, personnel, laws and regulations, machines, etc. We offer a high-quality and broad assortment, also for the Scandinavian market. In these countries, it can naturally be very cold, so mostly hardy varieties are sent there. In fact, we send everything from small C5 to large solitaires to these countries. There continues to be an increasing demand for conifers & shrubs in these countries. At the moment, the flatworm is a big issue they are very focused on, and this is already causing some problems for various companies.”

FUTUREPROOF CULTIVATION IN THE NURSERY STOCK INDUSTRY: ESSENTIAL FOR PEOPLE, ENVIRONMENT AND MARKET
The nursery stock industry in the Netherlands is moving fast. Increasingly more growers are focusing on sustainable growing: a way of production that is not only economically viable but also takes into account the environment, biodiversity, and changing climatic conditions. This approach is crucial because the industry faces major challenges. Think of stricter environmental regulations, decreasing availability of plant protection products, and a changing climate with more extreme weather conditions.
Sustainable growing means, among other things, focusing on soil health, water conservation, integrated pest management, and reducing CO2 emissions. Innovations such as precision farming, biological control agents, and sustainable energy sources are gaining ground. Growers are also investing in species that are more resistant to drought, diseases, and pests, so they are less reliant on chemical products. The importance of this extends beyond the industry itself. Sustainably grown trees and plants contribute to a healthy living environment, urban greening, and climate adaptation. They improve air
quality, provide cooling in cities, and help retain water during heavy rainfall. Sustainability, being futureproof, is not just about ecology, but also about people. The industry is facing a tight labour market and an ageing workforce.
This makes making the profession more attractive, improving working conditions, and providing education crucial. The tree nursery industry proves that sustainability and quality can go hand in hand. By investing in sustainable growing methods now, the industry is building a resilient future and strengthening its position in the international market. Sustainable growing is a necessity, and
to remain sustainable, the industry must continue to invest in knowledge, collaboration, and innovation. It is time for this awareness to be widely shared, both within and outside the industry. An important key lies in strengthening the chain: from grower to end customer. Only by working together on sustainable solutions can the industry maintain its strong international position and contribute to a greener living environment.
At the trade fair GrootGroenPlus, held from 1-3 October in Zundert, this topic will be a focal point. The KwekersBode already checked in with some of the participants.
Streng Growers - Growing with vision and responsibility
In the heart of the tree-growing region of Boskoop, you will find Streng Growers - a modern nursery where craftsmanship, sustainability, and future vision come together. A wide assortment of climbing plants, fruit plants, garden plants is grown, and high-quality products are delivered year-round to garden centres, other retail forms, wholesalers, and green space providers.
What is the strength of the company?
We asked owner Ronald Streng. “Our strength? A strong seasonal offering and a clear direction
Rabobank promotes sustainability
Rabobank, partner of GrootGroenPlus, feels closely involved with the tree nursery industry as an advisor and financier. How do they see the developments in this industry in terms of sustainability and future-proofing?
The KwekersBode spoke about this with René Dekkers, Account Manager Food & Agri at the Food & Agriteam Kring Zuidwest-Nederland. “Being future-proof is of the utmost importance for companies. It goes beyond sustainability,” says René Dekkers. “How do you function as a company within the frameworks set by society and regulations? We see that the vast majority of growers are doing their best to meet all those demands, and we also see that suppliers are working on it. There’s always room for improvement, but major steps are
towards visually attractive plants that immediately appeal on the shelf and in the garden.”
Relevant throughout the year “At Streng Growers, everything revolves around continuity and quality,” says Ronald. “We provide a wide range of plants throughout the year that moves with the season and with consumer demand. In the winter months, we offer, among other things, Gaultheria ‘Big Berry’ and Picea, also in decorative versions that perfectly match the Christmas period. This segment is developing and represents an important growth direction for the coming years. In addition, we are increasingly focusing on visual garden
being taken. It is a shame that often in discussions - and we also see that in the media - emotion seems to outweigh reason. The consumer often wants a clean product, but is that same consumer willing to accept that spot on that apple, or an imperfection on a plant? Everything has a cost factor, and that will inevitably be reflected in the price.”
is that same consumer willing to accept that spot on
Dekkers sees the activities at the cooperative association Treeport as a good example. “Treeport is very active in this area; they are focused on water quality and achieving as little leaching of chemicals as possible. There is an eye for the problem, and they are addressing it, not digging their heels in the sand, but
being constructive.”
being constructive.” the of businesses and also encourages
Rabobank places great importance on the sustainability and future-proofing of businesses and also encourages this. René Dekkers mentions, for example, the interest rate discount (sustainability discount) and the SME sustainability contribution with a financing request. “The assessment of how the company is working on sustainability and future-proofing is an important factor in evaluating the financing request. If profitability is under pressure and there are doubts about the commitment to sustainability and future-proofing, then it’s better not to proceed.”

plants - species with direct ornamental value, a strong appearance, and clear added value for the consumer. Plants that stand out and convince.”
From a family business to a modern, growing company Streng Growers was founded in 1978 by Nico and Jolanda Streng, who started with open-ground products. In the 1990s, they made the switch to container-grown plants, focusing on climbing plants and fruit crops. With the entry of their son Ronald Streng in 2009, a new phase of growth began. In 2019, there was an expansion, and the name changed: Streng Growers B.V. was born - ready for the future.
Ready for the future, that also means focusing on sustainability and future-proofing? “Responsible growing is a given for us,” is Ronald’s response. “Sustainability is not a separate theme, but is an essential part of all our business operations. We are certified according to MPS-A, MPS-GAP, GRASP, SKAL, andfor our edible products - also GGN. With this, we meet strict requirements for safety, traceability, and environmental care.” What does that mean in practice?
Ronald: “We mainly grow from our own propagation material and use biological pest control and natural predators. In addition, we keep the company clean, organised, and hygienic, and use recycled pots and labels. We also work with a closed water system without discharge into surface water, and the solar panels on the roof provide us with mostly our own energy.”
“To be future-proof, we must keep moving and continue to improve,” says Ronald. “At Streng Growers, we never stand still. We are constantly looking for ways to optimise our crops - whether it is about resilience, appearance, or logistical efficiency. We follow developments closely, experiment with sustainable substrates, and continuously look at how we can make our plants stronger and more attractive. With our commitment to quality, sustainability,
and visual presentation, we are building a future-proof company and plants that are more than just green: they tell a story of craftsmanship, care, and love for the profession.”
Zorn Baumschulen, fruit trees from the tree nursery area of Pinneberg
The KwekersBode also took a look across the eastern border at a new participant at GrootGroenPlus. Zorn Baumschulen from Tangstedt, in the important tree nursery area around Pinneberg, was founded in 1981 in Tangstedt by Wiebke and Werner Zorn and moved to a new location in Tangstedt in 2017. Here, spacious halls and fields are now available. From the beginning, the focus was on berry fruit. This range was continuously further developed, so that now wild fruits, pome and stone fruits, and some specialities such as figs and rhubarb can be offered in the best quality.
Better ornamental shrubs in garden centre quality complete the assortment
EXPERT CENTRE LIVE, the place where innovation and sustainability meet Sustainability is also playing a significant role with the ‘suppliers’ of the industry. They are also responding to the societal need to grow as sustainably and future-proof as possible. We asked Marcel Hubers, Technical Manager Ornamentals & Garden Europe & Sustainability at Syngenta, for his company’s vision. Hubers: “At Syngenta, we consciously make the most sustainable choices. It is an integral part of everything we do. It makes us aware of our responsibilities and is the driving force behind our visions. Our goal is to (among other things) reduce the ecological footprint of land and horticulture, protect crops without impact on humans, the environment, and surroundings, and reduce CO2 emissions in land and horticulture.”
We place a high value on
“Our propagation is mainly done in-house through cuttings, layering, eye grafting, and budding,” says owner Andreas Zorn. “Our shrubs are grown both in containers and in the ground. We place a high value on the best quality in production. Our very wide range of fruit is
complemented by ornamental shrubs and solitaire plants.” Garden centres are important customers of the tree nursery. Andreas Zorn: “We offer our garden centre customers a wide range of fruit trees, with a focus on pome and stone fruits, berries, and wild fruits. The fruit assortment is complemented with specialities such as figs, rhubarb, kiwis, cornels, pecan nuts, and much more.” In addition, there is an extensive assortment of ornamental shrubs, with ornamental cherries and ornamental apples particularly worth mentioning. Strong qualities are offered in containers of 5-7.5-10 litres, with 80 cm high ornamental stems as the highlight. Andreas Zorn: “Our plants are also very popular as starting material for solitaire planting. By consistently pre-growing in the ground and regular pruning, we achieve a constant high quality. In the cultivation and processing of each individual plant, we find craftmanship very important. Through a closed water loop, careful and targeted watering, cultivation in peat-poor substrates, and sustainable use of fertilisers and plant protection products, we consciously produce sustainably.”
“We look optimistically to the future,” says Andreas Zorn. “Plants are the solution to some of the major problems of our time. Climate change, fine dust, and the wellbeing effect will increase the demand for plants in the future.”

Hubers explains that Syngenta’s ambition is summarised in 4 sustainability pillars. “The first is accelerating innovation, for growers and the environment. The focus is on biologicals, ICM solutions, and digital solutions. The second pillar of our sustainability policy is reducing the impact of climate change and urbanisation, for example. The third pillar is support through education, best practices, training, and stewardship programmes. The fourth pillar is achieving more complete solutions: commercial partnerships, stewardship programmes with various partners in the industry.”

name Total Transplant Solutions, TTS now offers an integrated package of Agri-plugs, specialised air trays, transport bins, and planting machines, all designed to work seamlessly together. Tolenaars’ motto is: ‘If you want to automate, you have to standardise!’ And that is precisely what this standardised package offers.”
contained within the plug and prevents overgrowth into root cloth-plants develop stronger root systems. Moreover, these trays enable higher planting densities. “With a 30-millimetre plug, we can accommodate 900 plants per square metre, compared to just 600 previously,” Tolenaars notes. “That translates to lower costs per square metre and optimal space utilisation.”
One of the most innovative products are the agri-plugs: compressed plugs encased in biodegradable paper. These
plugs can be produced from various substrate blends, with customers free to supply their own materials. “We don’t dictate changes to the customer; instead, we adapt wherever possible,” explains Tolenaars. “If a customer wants to use their own mix, we compress it into a paper sleeve.” Agri-plug production is currently handled in-house in Rijsbergen.
their own mix, we compress it into a paper sleeve. Agri-plug production is Rijsbergen.”
Reuse and refilling of Airtrays
Reusable Hard Plastic Airtrays
The agri-plugs are used in combination with so-called Airtrays, a technology inspired by practices in the United States. With smart features such as air and water chambers and a technique called ‘air pruning - which keeps roots
Sustainability is a key pillar of TTS’s business philosophy. The use of reusable hard plastic trays is part of a circular strategy. TTS also offers a tray washing service for a fee, enabling trays to be cleaned and refilled with plugs. “This is not only environmentally friendly but also ultimately more economical,” Tolenaars adds. “With the circular economy gaining traction, this is a logical step.”
From Rijsbergen soil to
Internal and external transport solutions
“The reusable air trays can be stacked on Euro pallets after washing and filling,” he continues. “For logistics in the greenhouse or tray field, we provide a cultivation transport frame. For transport to the field, we offer special transport boxes capable of carrying up to 9,000 plants in a single load.”
Step-by-step implementation
A distinctive feature of this total solution is its modular design. Each component can be purchased, leased, or rented individually and implemented in phases. This allows growers to automate gradually. “Many growers start small, for example with just the trays or plugs, and then add the rest later,” explains Tolenaars. “This makes automation financially accessible, avoiding high upfront investments.”
Scaling up
To support storage and plug production, Tolenaars has acquired an additional location, which will become operational in 2026. He believes scaling up is essential to meet increased domestic and international demand. Tree nurseries, plant growers, floriculturists, vegetable growers in the Netherlands, and even Christmas tree and pepper producers in the United States are already using the modular system (www.dutchmantreefarms.com).
Collaboration with Telermaat Transplant Solutions now offers a comprehensive package of agri-plugs,
with each other. In collaboration with Telermaat - a company focused on the promotion, sales, and advisory services for trays and related products within the tree nursery sector - this total solution is being made more widely available and even better tailored to practical needs. Tolenaars’ motto is: “If you want to automate, you need to standardize!” And this is exactly the standardized package we offer.
Total solution
With Total Transplant Solutions, TTS takes a bold step forward - where innovation, automation, and customer focus come together in a total solution that makes modern cultivation practices more efficient, sustainable, and user-friendly.
FROM TRADITIONAL CULTIVATION TO DATA-DRIVEN INNOVATION:
Mabo Boomkwekerijen shows how technology transforms the nursery stock industry
The nursery stock industry is in the middle of a digital revolution. Where experience and craftsmanship used to be the most important pillars, now, data and technology are becoming increasingly more important. Precision agriculture, using sensors, drones, and advanced software, makes it possible to make decisions on irrigation, fertilisation, and crop protection per tree or plot. These developments do not only promise more efficiency, but also a more sustainable cultivation. The KwekersBode decided to look into it: what is currently being developed when it comes to precision agriculture, and where can we see this in practice?
Research program Precision Agriculture 4.0
Wageningen University & Research (WUR) plays a leading role in the development of precision agriculture within the tree nursery industry. Their research program ‘Precision Agriculture 4.0’ focuses on integrating advanced technologies such as GPS, sensors, and drones to optimise crop management. This allows growers to make decisions at the plant level, leading to more efficient use of resources and more sustainable cultivation practices.
WUR expert Corné Kempenaar: “Precision agriculture offers the possibility to produce more with fewer resources, which is essential for the sustainable future of agriculture.” By combining traditional knowledge with modern technology, growers can better respond to the specific needs of their crops and the soil conditions of their plots.
WUR’s research highlights that the use of precision techniques, such as soil scans and sensors, not only increases efficiency but also contributes to the sustainability of the cultivation. Through accurate data analysis, growers can take targeted actions, such as adjusting irrigation schedules or detecting diseases in time, leading to healthier and more productive crops.
The collaboration between knowledge institutions like WUR and companies like Syngenta illustrates the power of integrating science and practice. By jointly investing in research and technology, they can help the tree nursery industry become more efficient, sustainable, and future-proof.
INTERRA® Scan as a tool for ground cultivation
Maurice Kok, crop advisor at Syngenta Crop Protection, is particularly enthusiastic about the INTERRA® Scan as an essential tool for growers in the ornamental horticulture and tree nursery industries. This advanced soil scanning
technology provides in-depth insights into soil conditions, including parameters such as pH, organic matter, nutrients, and water retention capacity.
With over 800 measurement points per hectare, the scan helps growers accurately map variations within their plots. Kok explains: “With the INTERRA® Scan, you can accurately map soil variation, such as macro/micro-nutrients, organic matter, and available water. This gives you all the data you need to optimise soil health in the long term.”
By using this detailed soil data, growers can take targeted measures, such as
variable application of fertilisers and selecting suitable tree species for specific soil conditions. This not only leads to more efficient use of resources but also to a more sustainable and healthier cultivation practice.
Log & Solve dashboard for substrate
While INTERRA® Scan focuses on soil analysis, Log & Solve focuses on substrate. Log & Solve, originally developed by Klasmann-Deilmann and since November 2024 owned by 30MHz from Rotterdam, has established itself as a leading digital platform for crop registration and management.
Log & Solve offers growers a comprehensive dashboard where various cultivation data are collected and analysed. From sensor measurements to lab analyses and cultivation actions, the platform allows users to monitor and adjust their cultivation processes accurately. This data-driven approach leads to more efficient and sustainable cultivation methods.
Gerard Flinterman, who leads the Log & Solve team, emphasises how important this is: “It has become clear in recent times that delivery reliability is the most important value for growers. This means reliable, timely delivery of the right quality. Using the crop registration program, users can better manage their cultivation towards delivery reliability.”
Example: Mabo Boomkwekerijen and data-driven cultivation Mabo Boomkwekerijen, located in Randwijk, is a pioneer in precision farming. Under the leadership of Niels Mauritz, who runs the company together with his father, technology is used to monitor and improve soil health.
Niels Mauritz emphasises the importance of soil scans to gain insights into soil composition. While traditional knowledge remains valuable, the data supports the grower’s intuition. “My intuition backed up with data,” he summarises.
Mabo Boomkwekerijen uses sensors, such as those from Aquafeed, to measure the suction tension of the soil. These data are used to create task maps for spreading compost and manure, enabling precise and efficient fertilisation.
“You need to plan ahead,” notes Niels, as processing the scans takes several weeks.
A concrete example of this approach is the variable application of compost based on the scanned soil data. In areas with a low organic matter content, more compost was applied to improve soil quality.
“We applied only 20 tons per hectare. Where the organic matter content was low, we made quite a serious variation,” says Sven van Kalkeren, who works on behalf of Niels Mauritz at Mabo
Boomkwekerijen.
Additionally, the soil maps are used to determine which tree species are best suited for specific parts of the plot, considering factors such as soil heaviness and moisture.
Although the use of drones and advanced sensors offers potential, Niels acknowledges that the diversity of tree species in their nursery makes it difficult to work fully data-driven.
“If you have 150 species, you need 150 sensors to specifically manage everything with data,” Niels explains. Nevertheless, he foresees that the role of data and technology will increase in the future, with the goal of achieving healthier and more sustainable cultivation.
Sven van Kalkeren sees a growing role for precision farming in the future, especially considering the increasingly stringent fertiliser legislation and the need to manage resources more efficiently.
“Soil is the foundation, I always say. So, you need to do something with it for those five years, and that’s possible with precision farming,” he emphasises. “And the possibilities are getting better.”
Data and technology in the tree nursery: the future vision?
The integration of data and technology in the nursery stock is not a temporary trend, but a lasting development. Does this mean there will only be room for precision farming in the future? Probably not.
Growers who open themselves up to innovation and are willing to invest in knowledge and resources may have an advantage when facing the challenges of the future. By cleverly combining traditional expertise with modern technology, they can strengthen their business and contribute to a more sustainable industry. At the same time, of course, it is not the only way.
same time, of course, it is not the only
This integration of technology into the nursery stock industry primarily shows that innovation and sustainability can go hand in hand. Mabo Boomkwekerijen is an example of how traditional knowledge combined with modern technology can lead to future-proof and efficient cultivation.

New generation takes over: Wernhout tree nursery rebranded as De
Weimer
WERNHOUT - As of 1 July, Boomkwekerij Leenaerts-Halters & Zn. will officially be in the hands of Corné Leenaerts and his wife Cindy. This marks the continuation of the family business by the next generation, located in the hamlet of De Weimer. Fittingly, the nursery will also adopt a new name: Boomkwekerij De Weimer.
BY ADDO SPRANGERS
“The name change underscores the new phase our company is entering,” Corné Leenaerts explains. His parents are stepping down after decades of dedication, although Corné has already been managing the day-to-day operations for several years. “For us, the takeover feels more like a formal step: our course remains consistent, with continued focus on diversification and professionalisation. We’ve already been working towards this in earlier years.”
The nursery combines open soil production-including seedlings and cuttings under contract-with approximately two hectares of pot and container cultivation. Key products include hydrangeas, ornamental shrubs, and roses, much of which is destined for the landscaping market and garden centres. “Our customers are mainly in the Netherlands, Belgium, and parts of Germany,” says Corné. “Belgium has almost become a home market for us.”
A notable aspect of the takeover is Corné’s collaboration with his wife Cindy. “She joined the business two years ago, coming from a completely different industry. Running the business together feels empowering and brings us closer as a company.” For the staff, little will change: the entire team will remain on board. The takeover thus represents a smooth generational transition with a strong focus on continuity and the future.

GROWERS MUST ADAPT THEIR ASSORTMENT TO CLIMATE CHANGE
Growing is not only for today and tomorrow; a good grower is already thinking about the future. Climate change, changing consumer demand, and stricter regulations determine which tree species are future-proof. Which species will thrive and which will disappear? Which tree species will dominate in the next 20 years? How can growers prepare for the changing market?
The climate is changing, and it’s happening faster than we may think. What will that mean for the assortment of trees we are currently growing and planting? De KwekersBode listened to dendrologist Jaap Smit, green curator of Trompenburg Gardens & Arboretum in Rotterdam. “Yes, our climate is really changing at a fast pace,” says Smit. “If you look at the KNMI statistics from the last 30 years, you can see how fast it has gone. And that has significant consequences. If we look at urban green spaces, we are now planting trees for a period of 60-70 years. If we take that rapid climate change and increasing ‘urban heat’ into account, we can roughly conclude that we are moving from a maritime climate towards a continental climate, with hot dry summers and wet winters.
will also have to adapt their range, and it is really high time to get started with that. The origin will become crucial. So, sending young plants from here to Eastern Europe to be grown there and then bringing them back is not practical. Essentially, nothing has changed, the origin is still from here. The range must be focused on the purpose for which it is used; beauty is no longer decisive. Municipalities will plant trees for a period of ten years instead of the half-century of the past. There will be a growing need for fast-growing trees that improve liveability; that can withstand heat, promote biodiversity, tolerate smaller growing spaces
That also means that winter hardiness zones are shifting. As a result, certain native tree species have had their day, especially in urban areas. I would advise those involved in selecting species for planting in urban areas and along roads to broaden their perspective. Choose climate-resistant and choose from the nearly 1000 different species that are grown in our country. Wageningen University & Research (WUR) even estimates that 40% of native flora will be extinct by the end of this century. So, think of popular native species like beech, oak, rowan, and birch.”
This not only has consequences for planting, but also for the growers. Jaap Smit: “Growers of standard and park trees, as well as forest and hedge plants,
of the past. There will be a growing need for liveability; that can withstand
due to all the cables and pipelines being placed underground for the energy transition, and trees that capture fine dust. Heat- and drought-resistant species such as plane tree, Hungarian oak (Quercus frainetto), Turkey oak (Quercus cerris), and cedar (Cedrus atlantica) offer potential. Also, species from Southern Europe and Asia deserve attention,” says Jaap Smit. A varied, climate-resistant range strengthens biodiversity and reduces risks. The right tree in the right place is essential for the urban and landscape greenery of tomorrow.
Boomkwekerij
De BatterijenGrowing is a craft
Boomkwekerij De Batterijen, located in the beautiful Ochten at the edge of Betuwe, is an all-round green company with four branches: the nursery, the container field and the garden centre with web
shop, the cash-and-carry, and the complete offering from design to support in planting. The tree nursery, covering a total of 20 hectares, is located on light river clay; the ideal location for growing fruit trees. De KwekersBode spoke with Alberto Stuurbrink of De Batterijen.
“Growing is a craft,” says Alberto, “and we like to keep it that way.” The fruit trees are grafted, chipped, and budded in the traditional, craft way. The entire growing process from rootstock to marketable tree is carefully guided by us.
The nursery specialises in growing native apple, pear, plum, and cherry trees, as well as soft fruits. In addition to modern fruit varieties, we grow many old Dutch fruit trees. Examples include Brabantse Bellefleur, Karmijn de Sonnaville, Ingrid Marie, Kleipeer, Meikers, and Eldense Blauwe. “Because we are always looking for new, better, or nostalgic trees and plants, we follow the latest trends and tree shapes closely,” says Alberto Stuurbrink.
Due to climatic developments, you see a shift in the range. Alberto: “Besides
Many misunderstandings about native and autochthonous
Marc Lodders, grower of many autochthonous products, notes that the terms native and autochthonous are often misused in many articles. Native does not automatically mean autochthonous, while Dutch autochthonous is always native. A good example is hawthorn. It naturally occurs
here and is therefore native, but not all hawthorn is autochthonous. Many seeds are grown from the Balkan countries in a completely different climate than what we have here. These plants are definitely not autochthonous and do not fit in our climate in terms of biodiversity and ecology, but they do appear
in the landscapes. The Dutch Tree Species List includes those stands that are truly autochthonous and can be supplied with a certificate. And so, each country has its own species list with the material considered autochthonous there.

the demand for the existing assortment, there is an increasing demand for Mediterranean fruit trees and shrubs such as apricot, kaki plants, and figs.” Alberto Stuurbrink also notes an increasing demand for sustainably grown plants. “We want to respond to that, but it always depends on the willingness of buyers to pay the higher price for them.” The demand for origin is not so much present with fruit trees but is certainly a factor for forest and hedge plants.
Boomkwekerij John de Lepper, strong in special varieties
Located in the beautiful Brabant Kempen, in the middle of one of the Acht Zaligheden, lies Boomkwekerij John de Lepper, with about 15 hectares of sandy soil. The broad assortment goes from shrubs and solitaires to multi-stemmed and shaped trees, Magnolia in tree form, to heavy park trees, with a focus on special species; lovingly and expertly grown by John and Esther de Lepper and their team. Architects, landscapers, and green space professionals across Europe form the target group for their trade contacts.
De KwekersBode asked John de Lepper for his opinion on growing in the future.
“Due to the rapidly changing climate, we will have to consider that species that are still planted everywhere now will disappear. Trees like Quercus, Tilia, and Acer will probably continue to be part of the assortment,” says John. “But
it’s time to start looking at other species, species that are suitable for the climatic conditions we have and will have.
According to the KNMI, all records for dry and wet weather have been broken in the last 20 years; we had a particularly wet year in 2024, and now it has been very dry for a long time. There is hardly any frost anymore. All these conditions make trees more susceptible to diseases and pests. So, we will need to produce trees that are resistant to that. A good example of that is Nyssa sylvatica, the black tupelo tree, originally from North America. Strong and proven cultivars include Nyssa sylvatica ‘Autumn Burst’ and ‘Big Lady.’ Ensuring good diversity is important.” There is another point that worries him: “The knowledge of plants is disappearing, not only among buyers but also among suppliers. Something really needs to be done about that. You can also see it in the shrinking supply of breeding, seed, and cuttings, and if you don’t have enough potting material, you can’t produce enough. There is real work to be done.”

assortment. Founded in 1967 by José Bogaert, the area covered at that time was 15 hectares. In 2001, the company was split into Handelskwekerij Bogaert bv (export-import) and Boomkwekerij Bogaert Koen. In 2016, son Laurens joined the business, and that year the tree nursery De Moor was acquired. The nursery mainly grows young trees in open ground (sizes 6/8, 8/10, 10/12, 12/14 being the most common sizes in their own assortment) on a total area of approximately 70 hectares. The assortment consists mainly of deciduous trees, hedge plants, and fruit trees. To obtain a varied range, the assortment is regularly supplemented with non-standard species. In addition to the nursery, the company also has a thriving wholesale business.
De KwekersBode also asked Koen Bogaert for his view on growing in the future. “Which trees will dominate in the coming decades? I think forest trees like Alnus, Betula, Carpinus, Sorbus, Quercus, Tilia, and a few more species,” says Bogaert. He believes that Fagus will face difficulties. “If you ask how to respond to the changing market, I think we in Belgium need to closely look at the nature organizations,” says Koen Bogaert. “What they ask for, people believe in, and those are mainly fruit trees and forest trees.”

WHY THE ENGINE ROOM IS GOING TO MAKE THE DIFFERENCE
The strategic value of mechanisation
The modern tree nursery faces a number of challenges. The availability of labour is decreasing, cost pressures are rising, and market demands are increasing. To make their business future-proof, growers need to organise their processes more efficiently. Mechanisation plays a key role in this. The machine room, which consists of processing, potting, and transport lines, is increasingly becoming the heart of the tree nursery.
Mechanisation makes it possible to automate a large part of the work. However, this requires careful alignment of technology and business operations. How does the grower ensure they maintain control, even when machines take over a larger portion of the work? The answer lies in managing the machines well and continually adjusting the technology to meet the specific needs of the business. Growers who develop their own machines, like Leuveld, can respond more quickly to these changes and thus retain control over their processes.
At Leuveld Boomkwekerijen, mechanisation is used to improve production processes and reduce labour costs. Leuveld has its own mechanisation company (KOBO), which enables the nursery to develop machines specifically tailored to their needs. An example of this is the cutting and inserting robot, which can cut or insert in three rows of plants simultaneously. The robot reduces work pressure and increases product uniformity.
Ronald Brand, Sales and Office Manager at Leuveld, explains: “Where previously three people would be cutting and trimming, now only one person operates the machine. This not only makes the work more efficient but also ensures that
nursery, increasing flexibility. However,
the grower can continue to align with the operational needs of their business.”
HETO: innovations for the tree nursery industry
In addition to Leuveld, HETO plays an important role in the mechanisation of the nursery stock industry. HETO offers a wide range of machines that can increase efficiency in nurseries. The machines not only help to increase
control remains with the grower, who must adjust and monitor the machines to ensure they are used correctly and continue to meet production needs.
The human side: the (future) grower as manager and planner
productivity but also offer the opportunity to streamline processes, reducing work pressure.
Machines such as the wide potting fork and tray filling line make potting and filling trays much faster. The wide potting fork can place up to 800 to 900 pots simultaneously at equal distances, significantly speeding up the potting process. The tray filling line offers an efficient way to fill trays with potting soil and create planting holes, largely automating manual labour. These innovations ease the work pressure, but the question remains: how does the grower maintain control over the process when a large part of the work is done by machines?
HETO also offers delivery buffer belts and refurbished buffer systems, which facilitate the movement of pots and improve logistical processes in nurseries.
These machines are mobile and can be used at different locations within the
While mechanisation reduces the physical work pressure, the human factor remains essential. The modern grower must retain control by acting as a manager and planner. Whereas the focus used to be on manual labour, it is now shifting to efficiently managing machines and processes. This means that the grower must increasingly think about how technology can be used to keep the business running while ensuring quality and efficiency.
At Leuveld Boomkwekerijen, the collaboration between the technical department and the nursery staff plays an important role. The company develops its machines in close collaboration with the people who actually use the machines. This ensures that the technology stays perfectly aligned with daily operations, so the grower can not only benefit from efficiency but also maintain control over quality and production outcomes.
With the increasing mechanisation in the nursery stock industry, the question arises about how the future grower will be prepared. The vocational education programme ‘Cultivation and Technology: Specialisation in Tree Nursery’ from Yuverta addresses this development by preparing students for a more strategic role. The programme focuses not only on the technical aspects of cultivation, crop protection, logistics, and sales, but also on general subjects like economics, ICT, and career guidance, giving students a broad foundation for their future career. In addition, there is a lot of attention for the use of modern machines and management skills.
Claudia Chi, Director of Yuverta Lifelong Development (LLO), says: “The programme is starting for the fourth time now. A new addition this year is that we offer leadership training at level 4, which is important for the career progression of employees.”
This approach supports growers in their transition to a role where they are not

only technically skilled but also able to retain control over their nursery in an increasingly technical environment.
Looking ahead: investments for the future
The question every grower asks themselves is: what investments are needed to keep up in the next 5 to 10 years? The progress in mechanisation, such as Leuveld’s cutting and inserting robot and HETO’s machines, shows that it’s not just about the machines themselves, but also how these machines can improve work processes. Investing in advanced machines means investing in a more efficient and sustainable business.
Leuveld has already developed several machines that are now not only used in their own nursery but are also supplied to other nurseries. This makes the tree nursery less dependent on external suppliers and helps the industry progress. HETO is also looking ahead and continues to work on new technologies that can further improve mechanisation in the
industry. Their machines are designed to increase productivity and improve working conditions, with a focus on sustainability and efficiency. However, it is important that the grower retains control so that the technology can be used optimally.
The voice of the grower
Many growers have now realised that mechanisation is no longer a luxury but a necessary step to keep their business future-proof. In conversations with growers who already use mechanisation, such as Leuveld’s and HETO’s machines, it shows that they consider these technologies to be important tools for a more efficient business. “The machines don’t take over the work, but they make the work easier and more efficient,” says a grower from Zundert.
The key to success lies in maintaining control. Growers must not only rely on the technology but also ensure that they maintain control over the processes that are essential for the success of their business.
“The annual, well-attended Techniekdag Boomteelt Zundert (technology day for tree nurseries Zundert) is known for showing innovations and exchanging knowledge and experiences. Most of the visitors and participants are also GGP participants, with a strong passion for both greenery and technology!”

BUFFER ZONES AT BCT ENHANCE NATURE AND ECONOMIC RETURNS
Multifunctional buffer strip: Fiber crop
In Zundert, at the Business Centre Treeport (BCT) site, an innovative test field is emerging, poised to significantly advance the sustainability of tree nursery practices. The buffer zone project-initiated by Treeport BCT Partners BV ROOTZ and executed in collaboration with a broad consortium-achieves three key objectives simultaneously: cleaner water, increased biodiversity, and economic returns for growers. “We are transforming what used to be an expense into a source of revenue,” says Merijn Maas.
Merijn Maas works at VARTA, a company involved in researching crops and agricultural residues for beneficial compounds, including their potential use as natural crop protection agents. VARTA is part of the consortium.
Consolidating initiatives
Charl Goossens, Maas’s colleague, clarifies that the buffer zone project evolved from several initially separate initiatives. “We received a mandate from the Brabantse Delta water board to improve water quality. Concurrently, our company was searching for locally grown alternatives for fibres in peat-free compost. Additionally, three students from HAS University, building upon previous US-based research on buffer zones, investigated whether similar buffer zones in the Netherlands could enhance surface water quality. These three streams converged at the BCT site.”
Research
Buffer zones-mandatory pesticide- and fertiliser-free areas along plots-are often perceived by growers as financial losses. This project aims to alter that
perception. A half-hectare test site hosts experimental strips planted with various tree species, including willow, poplar, and miscanthus, arranged in different combinations, each covering approximately 100 square metres. “We measure groundwater before and after these strips, collect runoff water, and analyse the ditch water quality,” explains Goossens. “This gives us precise insights into the purification capacity of each planting.” Groundcover plants such as standard grass, clover, and pollinatorfriendly herb mixes are also included, aimed not only at reducing nutrient and pesticide runoff but also at enriching soil life and insect diversity around nurseries.
Facts
The project is set for significant expansion, adding seven hectares of new buffer zones featuring various plant configurations. At the same time, laboratory trials will commence at specially equipped testing facilities at ROOTZ. “Here, we measure the purification capabilities of individual plants under controlled conditions, eliminating external influences like
ditches or rainfall,” Goossens says.
“This allows us to align theory closely with practice and establish robust, evidence-based conclusions.”
Economic returns
The economic aspect is crucial.
Harvesting fibres from buffer zones-for instance, for sustainable compost-can generate tangible revenue for growers.
“Admittedly, these fibres might not match the returns from ornamental conifers,” Maas acknowledges, “but they certainly offer revenue potential.
Rather than merely representing an expense, buffer zones become incomegenerating assets. Additionally, nurturing functional buffer zones can enhance a grower’s standing with water authorities, potentially resulting in greater regulatory flexibility.”
Joint effort
Several parties have joined forces to execute this initiative. ROOTZ hosts the research plots and laboratories.
“Every stakeholder in the value chain is involved,” Maas explains, “from
research and planting to processing and market placement. Only through such integration can the project truly succeed.”
Advice
Research outcomes will culminate in comprehensive guidelines within four years, offering applicability beyond the sandy soils of Zundert to other soil types, including peat soils. Merijn Maas hints at future developments: “We also aim to investigate purification capacities for contaminants such as PFAS. However, our immediate priority remains demonstrating the current efficacy and profitability of buffer zones.” Through knowledge, collaboration, and innovation, Treeport BCT Partners BV ROOTZ is paving a sustainable pathway, offering promising prospects for future tree nursery practices.
Open Day
During the ROOTZ Open Day on 18 September 2025, the guided tours will include visits to the buffer zone project.
