Dean Ricci

For those that were looking forward to improved business conditions in 2022 after a particularly challenging 2021, you might be saying, “bring on 2023.” This year has certainly not seen supply chain pressures decrease and there appears to be no end in sight. Lead times for materials and equipment are extended, fuel prices are at historical highs, we are seeing inflationary prices for capital and consumables, and if all those factors didn’t make things difficult, low unemployment rates can negatively impact the ability to recruit and retain valuable employees. How can business owners mitigate these risks in these extraordinary times? Focus on the components of their business that are within their control.

Place a high level of focus on production planning, inventory management, training, and applications of best practices. Look to eliminate the waste and non-value-added activities within your organization. One facet of applying best practices is to collaborate and visit with other contractors. I have made it a practice to visit fellow contractors to view their operations. No matter the size or length of time in business, I have always been able to gain a useful piece of information that I can incorporate into my business. Another great opportunity for collaboration is the INLA summer outing. Both suppliers and contractors are gracious enough to host a visit, allowing for the visitors to due a deep dive into supplier operations and the facets of intricate projects. (See pages 8–9 for details and registration.) This speaks volumes for our industry and shows us that even though we may be competitors, we are invested in improving the professionalism of our industry.

EXECUTIVE DIRECTOR’S MESSAGE Greetings to everyone! By now you all should have more than ample time to read the following message from your Executive Director. A word of caution, this particular message concerns not only industry news, but also a few personal tidbits thrown in. Before I get to the necessary industry news, here are a couple of miscellaneous thoughts from me personally.

Rick Haggard

First is some really great news! On June 10, 2022, I attended the 50th work anniversary of Garry Fisher. Garry worked directly for the Hobbs Family from 1972 to 2006, when at the time it was purchased and became Becker-Hobbs dba Hobbs Nursery and in 2018 Brent Schalk of Blue Grass Farms of Indiana became the owner. Officially opening in 2019, it is known today as Blue Grass Farms/Hobbs Yard. I was fortunate to spend about 40 years working with Garry. Garry exemplifies the verbiage associated with "dedicated worker." His primary concern, besides family, is his the need to be sure things operate in a timely manner with the nursery and sales yard whether it be irrigation, equipment operating correctly, customer needs, and perhaps the biggest asset — imploring the wellbeing and safety of other employees. Garry, you are definitely one in a “melon”/ million, especially given today’s employment scenarios. I wish you nothing but the best in the future, when and if you retire!

Garry Fisher and Rick Haggard

Secondly, after having a few conversations with other owners/managers of companies, I had to reflect on the past few years and the toils of emotional stress everyone went through. I know everyone refers to things that the COVID pandemic brought about with the uncertainty of where our industry would fall, good or bad. I too, found myself very concerned on how our members would be able to navigate the various pitfalls of Essential or Non-Essential status. Trust me there are many times I thought tirelessly of what would happen to me as an Executive Director and the other people that have always helped me directly and indirectly to keep the association going since its beginning in 1933. I definitely did not want to become a reason for the association becoming a possible failure. Fortunately, our industry was essential, and while 2021 was not a profitable year for the association, we were able to minimize our losses and forge ahead. It also showed to me that I had more support from others than I ever imagined, some I did not know except only by name.

Now let’s get to the exciting industry news!!!!! The Summer Meeting is starting to take shape and while not all details are “written in stone” the landscape tours will take place on August 4, 2022 at Geist Reservoir. (Exact times to be determined, but it will be Eastern Time, as a reminder for our northwest and southwest members.) The plan is to reduce the number of stops as most of the homes require various transportation challenges, especially the ones with water frontage. With the “Surf and Turf ” aspect of our tour, we plan to offer optional boat and van accessibility to get to each site. An initial tour took place on June 9, with our guide Jim Calvin, taking a few of us on his boat to look at a few possible tour sites. By the way, Jim and Melissa Calvin have offered their home on Geist Reservoir as a lunch break location on August 4. Dinner and auction will take place at Wasson’s Garden Center located near 126th and Olio Road for the evening. The host hotel will be The Courtyard by Marriott located in the Fishers District just off I-69 and 116th Street. We have solidified a price of $169.00 plus tax, per night with both King and Double Rooms options. Be sure to check the INLA website, INLA Facebook page, and a blast member email for the link. The next day will be the Shooting for Scholarships at the Indiana Gun Club like last year with the second opportunity to bid on some fabulous items. Any company wishing to donate a gift basket/gift card or other similar donations, start thinking upon reading this as all funds raised go to the scholarship fund. See page 8 & 9 for details and registration form. Also, remember to save the date of August 11, 2022 for the upcoming IOMA Golf Outing fundraiser, as this will help offset the costs associated with keeping INLA updated on potential positive/negative legislative impacts from legislation the Indiana General Assembly when it starts in January 2023. Please keep in mind that this is a long session, as budgets will be set during this time. See page 27 for registration and sponsorship form.

Top 10 Tips for Collecting a Good Sample Purdue University Extension, Plant & Pest Diagnostic Laboratory(PPDL) 1. Time is money: Don’t wait until the problem is widespread to send a sample. Many diseases and insects are manageable if caught early. 2. Dead plants tell no tales: Plants which are totally dead, dry or rotten are useless for accurate diagnosis. Collect declining but not completely dead ones. 3. What’s bugging you? Collect several examples of insects for ID, just in case some get damaged in shipping or if both males and females are needed. Many can be shipped in vials with 70% alcohol. More details at: 4. More is better: The main concern may be overlooked if you send only one plant, one insect or a single branch. Send plenty of material or whole plants if practical. Make sure samples are representative of what you are seeing. Digital images can help too!


5. Get to the root of the problem: Many plant problems are related to the roots and soil. Dig plants rather than pull them up to keep roots intact. Include plenty of the small roots and at least a cup of soil. 6. A place for everything: If soil gets on the leaves during shipment it can mask symptoms or even create a “disease” that wasn’t there at shipment. Keep soil around roots so they don’t dry out. Bag the roots and soil and tie at the main stem or secure with aluminum foil. Wrap foliage in newspaper lightly then pull the bag over the rest of the plant and tie the top loosely to keep foliage from drying out. Make sure foliage isn’t wet before packaging. 7. Details are important: The more you tell the diagnostic lab about the situation the better. Include name of plant, location, percent affected, symptoms of concern, fertilizers or pesticides used recently, and other details. For Plant or Weed ID please give full details requested on submission form. 8. Fresher is better: Mail or deliver samples as soon as you can. Store samples in a cooler on hot days until you can deliver or ship them. Avoid shipping samples on Fridays since most plants will start to rot after being in transit over a weekend. A next day delivery service is needed for urgent samples or those that may rot quickly in shipment.

A gift with INLA renewal!

9. Fragile, handle with care: Padded mailing envelopes may be used for samples that are not fragile, such as ears of corn, but crush proof boxes with crumpled newspaper for padding are preferred in most cases (essential for young and tender plant material). Insect vials must be padded to prevent breakage in shipment.

10. Know where to go for help: Most states have strong Extension Services associated with a state university. Extension Educators and university websites can be a great resource for problem solving.

There Mite Be A Problem Kenneth Cote, Indiana Department of Natural Resources, Division of Entomology and Plant Pathology This article is an introduction to a 3-part series on mites. Future articles will discuss the seasonality of mites and the types of species you may encounter in landscape, nursery and greenhouse environments. There will also be information on control strategies that can help you prevent damage from these pests.

Mites are neither spiders nor insects. They belong to the class Arachnida, order Acari. Ticks are in this order but belong to a different suborder. Mites are very abundant in our world and some acarologists believe that there may be more mite species than insect species on the earth. Mites not only feed on plants, but can also be found in the soil, in the joints of ant legs and even on your eye lashes. There are parasitic mites such as varroa mites on bees, bird mites, chiggers, straw itch mites, and even some species of mites that are found in aquatic environments. Finally, there are predatory mites that feed on other mites and insects. Typically, mites have an egg, larva (with six legs), protonymph, deutonymph, and adult stage in their life cycle. Mites can overwinter in bark cracks and buds either as adults or eggs depending on the species. As a rule, adult mites have eight legs unlike insects that have six legs as adults. However, adult mites in the family Eriophyidae have four legs located at the front of their bodies and their bodies are elongated as opposed to an oval shape like most mite species. Mite eggs are small round and sometimes possess a small projection called a stipe. Plant feeding mites can be one of the most destructive pests in landscape and greenhouse environments. Their high reproductive ability can result in large colonies that will quickly result in plant damage and sometimes even plant death. These pests often go unnoticed because of their small size which makes them difficult to detect. However, knowing what species of mites to monitor for and how to detect them can provide assistance in preventing serious plant damage.

Detection Monitoring for mites will require a 20x hand lens. In many cases you can often see mites feeding on the undersides of leaves towards the mid rib. However, 12

low populations levels of mites may be more difficult to see, especially on conifers. Mites species will be difficult to identify in the field, but using a few tricks you will be able to determine if mites are present and if they are a pest species. One of the easiest ways to determine if mites are active on your plants is by performing what I call the “beat test.” This is performed by shaking small branches over an 8.5" x 11" piece of white paper. Next, gently blow off the debris to see if mites remain on the paper. Do not blow too hard or you will blow off the mites. You can then use your hand lens to determine if mites are present on the paper. Sometimes you can also do the smear test by gently rubbing your hand across the paper to determine if mite bodies are present or it if is just dirt. Mites tend to leave a small smear trail when crushed. If the mites on the paper are moving very quickly, those are predatory mites as opposed to plant feeding mites which are often more abundant and sedentary on the paper. Plant feeding mites do not move as


rapidly as predatory feeding mites because their behavior is geared towards feeding on plants in one position. This behavior can also be observed on infest plants.

Identification Identification of mite species you are not familiar with may require a taxonomist. Males must be slide mounted and the shape of their genital plates must be examined to truly determine a species. However, there are some techniques you can use in the field to help you identify commonly encountered mite species. • Look to see if the mite is producing silk. Mites such as the twospotted spider mite will produce large amounts of silk or webbing, however this can often go unnoticed until population levels are fairly large. • Look at the location of the feeding activity. Certain species feed on the underside of leaves while others feed on the upper side of leaves or even in buds. • Mite eggs are very large and often almost ⅓ of the site of adult mites and can

be viewed with a 20x hand lens. The shape, color and size of the eggs can also provide information to assist with species identification. Large, oval shaped pink or reddish colored eggs are likely to be produced by beneficial predatory mites. Cream or yellow-colored eggs that are perfectly round are typically produced by plant feeding mites. The presence or absence of a stipe on the egg cans also provide insight into species identification. • Finally, consider the time of year the infestation is occurring. Certain species of mites are active during certain times of the year, this is often temperature dependent.

Control Mites can be very serious pests in landscape and greenhouse environments. Understanding the seasonality of mites and their preferred hosts can help you better monitor for early stages of mite outbreaks. Remember, early detection and intervention is key to preventing plant damage from mite feeding activity. A good mite control program incorporates a combination of tactics that includes both cultural, chemical, and biological control. When miticides are required to prevent serious plant injury, choose your product wisely. Make sure the miticide is labeled to control

the species of mite you are wanting to control. There are differences in product efficacy on different species of mites. Consider the population level and if beneficial predators are present that you wish to preserve. Also remember to read the label to determine if the product is labeled for your site. Some products labeled for the greenhouse are not labeled for the landscape. As always, be vigilant and monitor your plants on a regular schedule because there might (mite) be an undiagnosed problem that is already occurring.

Overlaying Concrete or Asphalt Pavements “Paver” Pete Baloglou, Techo-Bloc As the demand for interlocking concrete pavements (ICP), concrete paving slabs (CPS) and plank stones (PS) increases, so does the range of applications. Segmental permeable pavement (SPP) projects are also increasing exponentially in residential, builder/developer and commercial sectors. Though internationally proven, widespread national acceptance of porous systems is a few years away. Open graded permeable or traditional dense grade interlocking have made segmental unit paving more mainstream. What has gained immediate acceptance are the structural advantages and aesthetic appeal of ICP. The strength of ICP comes from a flexible system working with (not against it like ready-mix concrete) freeze and thaw cycles and frost heave. But what if you lessen or eliminate its flexibility? Such as overlaying it with concrete or asphalt pavements. So why, how, and what is the initial and life cycle cost of overlaying asphalt and concrete with paving stones?

Why overlay concrete or asphalt? 1. It’s already there and in good condition (only minor cracks). 2. It was poured too low and can use the height of the paver veneer. 3. Cost of excavation and aggregate base installation are cost prohibitive. 4. High water table application (or slab is poured as part of foundation). 5. Aesthetics (Paving stones just look better.) 6. Pools (liner/fiberglass), because of over-excavation and improper re-installment of soil or aggregates. 7. New construction (pour to resist settlement against foundation). How do you overlay an existing pavement? First, make sure there aren’t any imperfections in the surface outside of +/- 3/8" in 10' and that it’s graded (¼" per foot) away from the house or structure. Drains should be considered every 25'–30'. ICP are typically 97% impermeable, so surface and sub-surface (setting bed) drainage are needed. The above tolerances will give us both. If the surface is out of tolerance: 1. Milling (asphalt)/grinding (concrete) 2. Filling (cold patch) and (flowable base) 3. Cutting (remove and reinstate) F.Y.I. The best repair for asphalt is to cut out problem areas and reinstate with paving stones!

Once the surface and grade are correct, determine an edge type. The edge restraint will maintain consistent joint width, help create interlock and must be impact resistant. The most common types of overlay edges are: 1. Adhesion (hydraulic glue, expands into pores of pavement and paver while retaining flexibility) 2. Hammer drill and spiked PVC or aluminum edge (Concrete screws or power actuated nail gun are options) 3. Troweled reinforced concrete behind a precast unit like Avignon edge/curb 4. Xtreme edge or Perma-Edge fiber reinforced concrete

We are a recruiting agency specializing in seasonal to permanent staffing services for U.S. companies.

Several factors have left Puerto Rico with unemployment rates well above national average. Since Puerto Ricans have been U.S. citizens since 1917, they are not subject to the many visa labor restrictions. While there are regulations with the Puerto Rican Department of Labor, we have developed a program to obtain the necessary approvals to recruit in Puerto Rico and provide Puerto Rican laborers. We have also established recruiting networks in other areas of the United States that persistently sees high unemployment and an excess of laborers.

All are fine (acceptable) if they allow the setting bed to drain. For example, space/gaps or corrugated drain board between Avignon, mason cord or cotton sash under troweled concrete every 8" and glue under the header course with the flow of water. On the topic of header/ soldier courses, you can use an 8 cm (80 mm, 3 ⅛") unit like Westmount HD2+ or Blu 80, 6.5" x 13" as a border, and 6 cm (60 mm, 2 ⅜") paver as the field, on a 1 ¼" loose (⅞" pre-compacted) setting bed of ASTM C33 sand or AASHTO #8 clean, clear stone. Any combination of 100 mm (4"), 80 mm, 65 mm, 60 mm, 45 mm, or 30 mm can be used, as long as the field is elevated ⅛" above border and a bedding layer is used…both for drainage. Always pre-compact bedding because compaction occurs from the bottom up and achieving uniform density is otherwise too difficult. If using a 6 cm (2 ⅜") for both header and field, use enough adhesive (with the flow of water) to mirror the height of the fabric and a “brooming” (skim coat) of fine sand, typically ASTM c144 masonry sand, under the field. Ensure a quality non-woven or woven geotextile is between the concrete or asphalt and your setting bed also extends up the sides of edge unit or restraint. The geotextile will keep the bedding sand or aggregate from migrating into current or future cracks in the asphalt and concrete.

After the steps have been taken to a quality overlay, how long will it last? Well, quality pavers have a lifetime warranty, so we’re good there. The base (asphalt or concrete) due to drying and inflexibility, is the weak link. As the petroleum in the asphalt dries and the concrete “curls”, the inevitable cracks introduce water. Water is the lubricant that leads to decreased load capacity and increased freeze thaw susceptibility. Both failures are compounded by the questionable (if any) compaction of the subgrade, installation of a structural woven geotextile (over subgrade), and base installation (to 98% standard proctor density). When deciding to overlay, a cost-benefit analysis must be done. How much labor, equipment, material, and subcontractors will be consumed versus demolition and traditional aggregate flexible installation? What is the life cycle cost of the overlay versus traditional? Who is willing to warranty (if anyone) what’s below the setting bed and paving stones, paving slabs,

and plank stones? Either way pavers are the best choice and can be “unzipped” while subsurface repairs, such as crack filling, are made. This reinstatement characteristic will continue to give paving stones the upper hand in overlays. To encourage surface runoff and discourage saturation of units, joints and bedding, a post-construction wash and protectant should be used. Post-construction wash will clean the pores of manufacturing, storage, and construction debris, allowing for greater penetration. The protectant should be breathable, mineral, stain, and water repellent… color enhancement is a personal preference. The combination is encouraged on all hardscape projects unless the product is already factory protected, but more strongly recommended in overlay applications.

Joint Fill on Segmental Pavement “Paver” Pete Baloglou, Techo-Bloc Segmental pavements have a 7000year history of success. They have evolved from rough fitting stone and clay brick to dimensionally tolerant concrete. These concrete units, made indoor under controlled conditions, adhere to strict company-specific and industry standards of durability. Units have changed from only tightly fitted block units (Interlocking Concrete Pavements – ICP) that are handheld to include large format Concrete Paving Slabs (CPS), Planks Stone (PS), Segmental Permeable Pavement (SPP) the last of which allows storm water infiltration. All these products (ICP, CPS, PS, and SPP) are part of a paving system that gives superior performance. The system includes: 1. Classified, Amended and Compacted (or scarified) subgrade 2. Geotextile 3. Base 4. Edging 5. Bedding 6. Wearing course 7. Joint Fill Joint fill is last, but not least in importance. It’s characteristics and specifications are relevant to transfer of energy (loads), drainage, aesthetics, long term care, keeping storm water run-off on the surface, infiltration, and filtration. With so many benefits its best to look at ICP, CPS, and PS options for joints such as WCS (Washed Concrete Sand), Masonry Sand, with or without joint stabilizing protectant, polymeric sand, and jointing compounds first. Then the economic and environmental advantage of open, poorly graded aggregates like ASTM #8 and #9 stone with or without joint stabilizing protectants for SPP. Options for ICP, CPS and PS include: 1. WCS 2. Masonry Sand 3. Both above with Joint Stabilizing Protectant 4. Polymeric Sand 5. Jointing Compound Washed Concrete Sand, ASTM c33, (the same used in the manufacturer of concrete, hence the name) has been the

industry approved joint fill since ICP’s inception post World War 2. Its course, angular, large (for sand) particles with less than 5% passing the 200 sieve make it a natural choice for drainage and vertical interlock. Vertical interlock (sand in the joint) won’t allow a paver (paving stone) to move independent of its tightly fitted (1/16" to 3/16") neighbor, commonly called shear transfer of energy. WCS’s gradation makes it time consuming to get into the joint, but it stays in longer and is a strong option. Masonry Sand, ASTM c144, is round, like sized with up to 5% passing the 200 sieve typically used in mortar for masonry projects. This sand goes into the joint quickly and cleanly. Cost is low and availability high, making this choice an industry standard one. Tying together WCS and Masonry Sand can be a joint stabilizing protectant. These breathable, penetrating, often stain resistant and color boosting, protectants, help bind jointing sand together with a mix of siloxane and silane (a hybrid) while caring for your pavement investment. Joint stabilization and pavement finish protection for 1-3, 3-5, 5-10+ years, depending on environment and traffic, is a great onetwo punch. Like Jake Boyer Business Unit Leader — Clean and Protect Group ProSoCo points out “…Joint Stabilizer not only provides protection to the sand joint by consolidating loosely bound sand particles, preventing weed growth and joint degradation, but also to the surface of the pavers, providing long lasting water and stain repellency…”.

Polymeric sand are polymer enhanced, water activated ASTM c144 sand that are bagged and ready for joint fill. Many options exist on the market with differing features, benefits and value.” When choosing Polymeric sand, key features such as compliance with OSHA’s PEL and Rapid Set Technology making joints rain safe in 15-minutes are extremely important to our clients. Our 15-year warranty gives them confidence that our products are durable and will last.” George Beiter, VP of Sales for Flexlock/Alliance state that additional advantages of bagged dried products like polymeric sand are staging, production, and low waste ratios. Finally, Jointing Compound, a wet purchased (in buckets) and applied joint fill for typically wider joints (3/16"–¼" +) while still maintaining interlock. Products exist for pedestrian only and vehicular, so read the label and seek consultation. All weather (above freezing) is this options key advantage and application. Installation in a rain event helps, giving clients access to the pavement sooner and contractor final payment on schedule. Like Eamonn McCullough of Azpects says about Jointing Compound “…gives the homeowner a very durable and aesthetically pleasing product they can easily maintain.” The E^2 Advantage (economic and environmental) of SPP has been a windfall for city planners, engineers, architects, and residential landscape designers and contractors. Combining a pronounced joint and rigid, deicing chemical resistant (Joint Fill on Segmental Pavement continues page 20.)

Joint FIll on Segmental Pavement (continued from page 18) concrete units (pavers or slabs) with an open, poorly graded joint fill is a SWM (Storm Water Management) asset. The joint fill should be ASTM #8 or #9 stone depending on spacing. ASTM #8 (⅜" to ¼") clean stone ideal for joint spaces from ½" to 1"+. ASTM #9 stone (⅛" to 3/16") clean stone works for ¼"to ½" tighter jointed SPP systems. Both have 90% fractured face, are less than 5% passing the 200 sieve, are hardness tested, with a narrow, poorly graded range of particles. A solution these aggregates offer in SPP is the almost infinite receptor points each stone possesses for filtration of contaminates. Contaminates like TSS (Total Suspended Solids), organics, petroleum distilates, heavy metals like brake dust, etc…. attach to the receptor points and can be agitated and removed to increase infiltration if ponding water is observed. Open graded joint fill also generates microbes (bacterium) that will consume these harmful contaminates. Clean stone for SPP jointing can be a great color and texture enhancement to the paving product. “AquaRock” is a bagged ASTM #9 for permeable pavements. This joint material has a shape, hardness, and gradation that industry professionals specify with a look that compliments the pavements

aesthetics.” George Beiter VP Sales Flexlock/ Alliance These ASTM #8 and #9 course angular particles remain securely in the joint especially when subject to microscopic airborne particles even on steep slopes, snow plowed areas, pool decks, etc… but a joint stabilizing protectant can assist. In addition to joint stabilization these protectants benefit deicing salt resistance, ease of long term care, and breathability, representing a tremendous value with very little reduction in infiltration. ICP, CPS, PS and SPP have helped define the historic and modern hardscape industry. Their success can be attributed to some manufacturers uncompromising commitment to quality and service. System standards have also added to their viability. These standards are ‘horizon by horizon’ in writing specifications for type, application and life cycle of the pavement. The final horizon for these systems is joint fill. Joint fill as we’ve seen isn’t just a sweep, wet, and run process. The focus on this final detail of segmental pavement can be the difference between success and failure and you’re too far along for the latter. Joints filled, consolidated, and stabilized gives these lifetime pavements lifetime enjoyment.

Wasson Nursery, Inc. Mary Breidenbach, Indiana Nursery & Landscape News To tie into our upcoming Summer Meeting 2022, we chose to highlight the event’s host, Wasson Nursery, Inc. Wasson Nursery is a family-owned landscape company with garden centers throughout east central Indiana and specializing in residential landscape design and lawn and garden services. We spoke with Bob Wasson, who along with his brother Dan Wasson, Jr. runs the company, which was started by their father Dan Wasson, Sr. 45 years ago. In 1977 the owner of the small nursery in Union City, Indiana who Dan Wasson, Sr. worked for, offered to sell the company to him. With a few loans Dan Sr. purchased the nursery and hired two friends to help him. “His entry into the business was timed well with the growth of the industry,” shared Bob. “As the business matured, we caught a good trend and expanded to three locations by following our customers. Our work first grew in Muncie, so we opened the Muncie store in 2008. And in 2017, we opened our Fishers store as we saw more work coming from the Indianapolis area. After 45 years at the helm Dan Wasson, Sr. just stepped down this spring and handed over the reins to his oldest son. Dan Wasson, Jr. is CEO and intimately oversees the landscape services. Bob Wasson is in charge of retail operations. While the transition is complete, Dan Wasson, Sr. still comes to work everyday and oversees their progress.

FISHERS 317-770-3321 11010 E 156th St Noblesville, IN 46060 UNION CITY 765-964-3477 1000 W Chestnut St Union City, IN 47390 MUNCIE 765-759-9000 3737 N. 500 West Muncie, IN 47304

Key to their success Without hesitation, Bob shares that the key to their success and overcoming problems is the creation of their executive team. In addition to Dan, Jr. and Bob, the executive team includes Zach Yeagy, COO; Royce Shewman, Controller; and HR Manager, Danielle Wasson (wife of Dan, Jr.). “We meet weekly to plan out the business and talk through the problems. Our business is run by committee and this works well for us. It allows a lot of thought and intention to be put into decisions and ideas to get tested. Specialties In addition to the three garden centers, Wasson Nursery offers landscape design, personal groundskeeping, tree and shrub care, and lawn care services. What ties this all together? “Our focus is on the homeowner and anything residential,” explained Bob. “Our very wide-range of services offered is all across the board. It’s unique and can be complicated to market because different areas of the business connect with people differently.” But yet it works because the homeowner remains the center of their attention. As Bob explained, “We put a lot of focus into our retails stores because it gives our landscaping services credibility and name recognition. We tell our retail staff in training, ‘Customer experience is so important because ultimately our goal is that they fall in love with our brand at the retail level and when they’re ready for that backyard patio we will transition them to landscape clients.’ So much starts with good experience in the store.” This is particularly true for the Fishers store, now in its sixth year. Bob shared, “the Fishers store is growing like crazy. Surrounded by tons of neighborhoods, the store supports their presence with about three-quarters of the landscape leads coming from the Indianapolis area.” While they’ve grown a lot since they added their second store in 2008, they are continually looking to the future for opportunities for growth. Here are some of the new projects that Bob shared with us: • Online shopping: To try to be prepared for the shift to online sales in the next 10 years, Wasson has shifted their in-store system to Shopify, an all-in-one shopping platform. With a generation of shoppers now more comfortable shopping online this change will allow them to be prepared for the evolving retail environment. 22


The Wasson Family: (seated, l to r) Carol and Dan Sr., and sons, Dan and Bob Wasson (standing)

• Top-notch facilities and equipment: Wasson’s is in the middle of planning a large landscape office expansion at the Muncie operation; purchasing 7-9 trucks with special beds to carry equipment more easily for their crews; and they’re investing in unique equipment to help their landscape teams work more efficiently. As Bob explained, “It’s our marketing piece to attract and retain employees. We want to provide the state of the art equipment to make their job easier and also make employees happy and proud to come to work at Wasson Nursery. • With the shift of people shopping online during COVID, Bob recently started a new online company called, “When you walk into a garden center you’re limited to what the store can stock and what’s available that day. So connects our wholesale vendors with our customers in that online people view our vendors’ inventory as our own. This increases our inventory tremendously and we guarantee a three-day delivery once purchased.” When the website kicked off, Wasson noticed people were placing purchases for much more than what they would purchase in person. But doesn’t this new venture directly compete with the garden centers’ website? “Yes, but it is marketed to a wider audience,” shared Bob. • Opening a bar: To add to the convenience and fun of retail shopping, plans are in the works to open a craft beer & wine bar in their Fishers garden center.

Challenges that come with growth For Wasson, the challenge was coming from a small business mentality and trying to turn that into a larger, smoother operating corporation. “We’ve grown from a sole proprietor where one person made the decisions to a company that has 12 managers and an executive team. Our biggest challenge was learning to delegate and to get the right people in the right seats. Jack-of-all-trades doesn’t work anymore. Everything can’t go through one person at the top. We needed to have people manage their own area. We needed to learn to trust and give people the freedom to learn and grow or we would be frozen by indecision. Delegation helped us progress and to get the right people on the bus and the wrong people off.” In contemplating their growth, Bob added that none of this would have been possible without the insight and work ethic of his dad. “My dad’s work ethic is instilled in Dan and I and is why we’re growing. Customer experience, attention to detail — we learned that from our father. So why is Wasson's an INLA member? “It ties us into the industry, we gain camaraderie and get to know the people behind the company. There is so much work to go around we’re not in competition, we’re all on the same team — trying to run our businesses better and sharing the same goals,” shared Bob. He is also really excited about INLA’s social media video project that started this spring. “Companies get highlighted on social media and that’s a big member benefit. It really showcases for me how INLA continues to find ways to helps build and support our business.” Bob also gives back to the INLA, too. As an INLA board member for the past six years, he currently serves as the communication chair and the membership chair. Remember: If you come to INLA’s Summer Meeting and take the Summer Tour on August 4, you’ll get a first-hand look at Wasson’s Fishers operation and also get to meet the dynamic duo behind Wasson Nursery.
