EXECUTIVE DIRECTOR'S
Good morning, day, evening or whatever the time of day you have set aside to read another tantalizing message from your Executive Director of the Indiana Nursery and Landscape Association. Please forgive me with this edition as the Indiana Pacers ar egetting ready to head to the NBA Finals, so if it starts going sideways or “off the rails”, I hope to bring it back at the end. It has been 25 years since their last NBA Finals appearance, wishing/hoping for a better outcome, but no matter the synergy that the Pacers have created should be bottled up and dispersed to every company showing how “teamwork can truly make the dreamwork”!
First and foremost, for those that are not aware Scott Johnsen, INLA Social Media Director of the INLA for 3 years resigned from that position on June 1, 2025. I truly thank Scott for his time in professionalizing our association and industry we represent. Showcasing many projects our members produce, as well as personal tailgate talks, member profiles in the magazine and just the overall enhancement our members and industry make creative beauty and artistry out of nature. Scott posted on Instagram, Facebook, etc. short reels much like a must see movie does with their trailers before the movie is shown. I totally understand the difficulty
of doing it for an association of over 300 members, compared to a private client that would utilize this as a way to entice and attract more business. Much Gratitude for showcasing our association and green industry through visual presentations. Scott has an article in this edition that is a must-read as well.
Secondly, THE INLA SUMMER MEETING and INEF Shooting for Scholarships, will be from August 6-8, 2025. Tentative plans are to host an educational visit on Wednesday August 6 to both Heartland Growers and Perennials Plus both located in Westfield. Thursday tours will include many stops in Holliday Farms subdivision showcasing many projects by various members of the INLA in Zionsville, plus a few other possible alternatives. Dinner on Thursday evening and first offerings of the INEF Auction, will take place at Perennials Plus located at 4510 West 166th Street, Westfield, IN 46074. John and Suzie Platte are planning a gala evening for all. As of this writing for the magazine, updated registration, hotel accommodations, sponsorships will be made available online in late June/Early July. Friday August 8, 2025 will be the 14th Annual Shooting for Scholarships at the Indiana Gun Club located at 14926 East 113th Street, Fortville IN 46040. Do not forget to keep checking the INLA Website for registration and link to hotel.
Now for my final thoughts regarding the various Call/Outs, Contractor on Tap events the INLA, especially through the brainchild of Scott Johnsen, to keep various areas of the state more involved by hosting these networking events. I would
personally like members to assist with a list of items that could help their companies or employes for that matter, to become more involved with the association. We try to keep cost as minimal to attendees as possible, by either accepting sponsorship or just a commitment of donations. Most have had a talk or 2 from specialist in certain areas, that have been germane to the areas, or new information that is not easily shared unless needed.
Last but not least the IOMA Golf Outing is July 17, 2025 at Twin Lakes Golf Club, celebrating its 16th year. The Corydon Group, IOMA’s Government Affairs Advisor will be on hand to engage in conversations regarding past and potential bills that became law or did not pass through committee but might return in 2026 legislation. The INLA, ILA, IICC, IPLLA and MRTF are all members as well as companies and employees of these associations are all represented as active members
and a part of IOMA. IOMA’s mission statement is to be “A Unified Voice Representing ALL Facets of the Green Industry.”
OK, since I added the last statement one of the bills that became law; was reducing the speed limit in certain areas on I-465 effective July 1, to 65 MPH. The last was in jest as if you are usually on certain areas of 465,during certain times of the, especially morning it seems, you better be in the far-right lane as the others are that speed or more, otherwise you are at the risk of seeing flashing lights from pedestrian vehicles to get out of the way :) ! Hard to fathom in this day and age; why so many people are in a rush to get to work.
Keepin it Green, Rick Haggard

Hello to all of my fellow INLA Members,
The Summer Solstice has come and gone and so the daylight hours now begin to wane. It wasn’t too many days after I had composed the previous Presidents Letter that I had found out that we, the good people at Greendell and Musselman Landscape Solutions, were going to be part of an acquisition. I’ll be honest, there’s always a fear of the unknown regardless of any reassurances given. Teams of individuals from our new consortium of partners showed up to help with the transition, which caused that fear to subside.
Why’s that you ask? Everyone they sent in to help with inventory, IT, and training had all been part of an acquisition themselves! From all across the country, they had all volunteered to travel to our locations to help onboard their newest partners. They were an amazing group of people and many of us are still in contact today. I feel that our biggest challenge has been learning a completely new computer system in our busiest season of the year. We have been embraced by our two newest local partners. Now we have the privilege of working alongside a group of fantastic people in the Indiana Region and access to an abundance of new resources. Leadership from all sides have been meeting regularly in efforts to develop a more consolidated program.
There are 3 results from this new chapter in our lives that I’m really grateful for.
Our people now have access to resources and benefits they’ve never had before.
Frank has a plan for retirement and he can do that in peace knowing that his employees futures are far more secure, and that we’re supported by a company with a lot more resources.
I am able continue to participate in playing a hand at creating a better future, not just for our Greendell and Musselman team, but also for all of our new partners at Automatic Supply and Stone Center.
What’s going on in the INLA?
Enough about what’s been going on in my life, let’s get back to business. The INLA Board had a wonderful opportunity to attend a Women of the Green Industry event hosted by Schneiders Nursery. For anyone who’s never been there, the view of the fields from the hilltop is worth the trip. The event was well attended and there were even two ladies present who might possibly qualify for the INEF Student Scholarship. On the very same evening, the INLA hosted it’s latest Contractors on Tap (CoT) event at Upland Brewery in Bloomington.
For those of you not familiar, CoT is a networking event that travels all around the state. Each one is unique and designed to offer an educational component, a networking component, and a beverage component to the experience. In the case of the latest CoT, there was food and drinks served, we had Rick Hughes from Automatic Supply give a little bit longer than 15 minute speech on choosing the right pump for a water feature, followed by a tour of the brewery. It was a great experience shared by 20 to 30 people in the industry.
Up next on the docket coming up in August will be our Annual Meeting and Summer tour. The Summer Tour Committee is currently headed up by our PresidentElect, Kevin Van Sessen. The Summer Tour,much like our CoT, travels to a different location each year. Last year we got to visit Notre Dame among many beautiful landscape projects. Red Hen Turf Farms was the gracious host of our Annual meeting and our Shooting for Scholarships event that always brings in a significant amount of funds to support our future Scholars. This year’s Summer tour will be in Central Indiana, skirting northern Indianapolis and it’s northernly suburbs. I’m excited to see the projects our Summer Committee has up their sleeves for the tour this year. Rounding out 2026 we’ve got our team in the Southwest territory in the bullpen getting warmed up. Can’t wait to see what Kent Wilhelmus and Dan from Aching Acres are going to surprise us with down there in natural stone country.
As always, I am humbled by the talent in our team. They constantly dedicate their effort, resources and most importantly time in support of our mission with the Indiana Nursery and Landscape Association. For many of us, this industry is not only a career, it’s something we wake up to as well as fall asleep to. Our friends are of the industry and often times our families. Thank you for continuing to allow me to serve. How about a book recommendation?

What I’ve Learned in Three Years Working with The INLA
By Scott Johnsen, Former Social Media Director, INLA
If you’ve ever tried to describe the green industry to someone outside of it, you know it’s not as simple as saying “plants and patios.” It’s design and dirt, sweat and science, legacy and innovation. It’s early mornings, late nights, and an unwavering devotion to building something beautiful. And if you want to find the heart of it all in Indiana, look no further than the Indiana Nursery and Landscape Association (INLA).
Three years ago, I stepped into this role with a camera, a keyboard, and a mission to help tell the story of an organization that—admittedly—I didn’t yet fully understand. What I found was a fiercely passionate community, built on generations of growers, builders, and visionaries. The INLA isn’t just a trade association. It’s a pulse, a force, and a home base for some of the most driven and passionate professionals I’ve ever met.
What struck me early on was how little ego exists within the INLA’s leadership. From multi-generational nursery owners to landscape designers breaking new ground, the common thread is a shared commitment to something bigger: stewardship. These are people who don’t just want to do business—they want to leave the land and the industry better than they found it.
Whether it’s lobbying for sound legislation, pushing for workforce development and education, or providing scholarships to the next wave of green industry professionals, the INLA has consistently invested in the future. I saw firsthand how members mentor one another, how contractors share trade secrets over a beer, and how ideas turn into action through committees and conferences.
Being behind the scenes of INLA events taught me something valuable: those who show up shape the future. From the moment you walk into the Indiana Green Expo, a Contractors on Tap, or just a room filled with the smiling faces of a board you haven’t seen in a few months, you feel it—that buzz of conversation, connection, and collective pride. These aren’t your average networking events. They’re proof that the INLA is alive with ideas and energy.
And it’s not just the big events. It’s the quiet phone calls to new members. The group texts planning an event. The after-hours brainstorming sessions of members whose earlier conversation sparked a new thought on the industry. I’ve seen how one idea, voiced in a breakout session, becomes a policy recommendation or a pilot program. In this association, the people who care make a
difference—because the platform is there, and the culture invites participation.
I’ve watched our members rally around sustainability, adapt to changing regulations, and embrace young talent with open arms. I’ve also witnessed them band together in hard times— supporting one another through economic uncertainty, labor shortages, and even personal loss. The INLA, at its core, is a group of people who care deeply— not just about plants and projects, but about people.
It’s easy to look at a social media page and think it’s just photos of trees and patios and nurseries and garden centers. But every image we posted told a deeper story: of family businesses enduring, of teams turning blueprints into memories, of professionals who pour their hearts into every square foot of soil they touch.
As I step away from my role, I’m filled with gratitude— not just for the experiences, but for the people. The board members who lead with humility. The contractors who always offered a warm welcome. The growers whose hands tell stories of decades in the dirt. Thank you for letting me tell your stories. Thank you for helping me grow, too.
The INLA will continue to thrive—not because of a title or a post or a logo, but because of the people who keep showing up, planting new ideas, and building something meaningful together.
If you’re reading this and you’re not a member yet, consider this your invitation. Because the INLA isn’t just a place to belong—it’s a place to build. And if you care about the future of the green industry, this is where you start.
With much admiration and respect, Scott Johnsen

IOMA - Indiana General Assembly Recap 2025
Despite the bleak outlook provided by April’s revenue forecast, the Indiana General Assembly fulfilled its constitutional duty and passed a budget. HEA 1001 provides a $46.1 billion biennial budget, which includes a $2 per pack tax increase on cigarettes and a proportional increase in taxes on all other tobacco products.
While they increased some taxes, they lowered (in some cases) taxes on homeowners and businesses. SEA 1 provides homeowners in 2026 with a 10% credit on every homestead’s bill up to $300. It capped the total Local Income Tax (LIT) rates for all counties at 2.9%, down from 3.75%, but also gave municipalities a new authority to impose a LIT of 1.2%. This will enable local units to offset some lost revenue, but to do so, they will be responsible for raising taxes. For businesses, the minimum business personal property (equipment) value threshold that triggers a tax payment on their equipment was raised from $80,000 to $2 million for tax year 2026. Finally, it also eliminates the 30% floor for depreciating equipment put into use after January 1, 2025. A business's tax rate is determined by taking an average of all its equipment's depreciated value (based on the equipment category), which previously could not go below 30%. To find out if your business qualifies, talk with a tax accountant.
Legislation with direct impact on the nursery and landscape industry included HB 1189 - Local regulation, which would have prohibited local government units from adopting an ordinance regulating or prohibiting motorized lawncare equipment or discriminating based on its so urce of fuel. Unrelated amendments were added to the bill, creating controversy and weighing it down to the point that it died in the Senate on the final day.
Local units may consider imposing regulations before the next session. In 2023, an Indiana city council convened a study committee to consider limiting lawn equipment to only electric-powered. IOMA and other stakeholders cited our concerns. Ultimately, the council did not move forward. This may encourage cities with this inclination to fast-track ordinances ahead of the next legislative session.
Other bills that died include HB 1184-State Chemist, authored by Representative Steve Bartels (R - Eckerty), which would have moved the Office of the Indiana State Chemist (OISC) from the Purdue School of Agriculture to the Indiana Department of Agriculture in 2027. The OISC is the regulatory and enforcement agency related to pesticides and fertilizers. It is part of a legislative push to make the office directly responsible to an elected official— in this case, the Lieutenant Governor. The House Agriculture and Rural Affairs Committee did not hear it, so it died.
There were multiple bills aimed at rooting out illegal immigrants by prohibiting employers from hiring them. One such bill, HB 1531 - Various Immigration Matters, authored by J.D. Prescott (RUnion City), prohibited employers with ten or more employees from knowingly or intentionally recruiting, hiring, or employing an unauthorized worker. Violations could result in a total or temporary suspension of an employer’s operating or business license (i.e., pesticide applicator). IOMA cited our concerns in testimony in front of the House Judiciary Committee, including the vagueness of the process of how the Attorney General's (AG) office initiates an investigation, and that, whatever the method of initiating, it could be used to harass member companies. It ultimately died in the Senate Judiciary Committee did not hear the bill. We will continue to see these kinds of bills while immigration is prev alent issue.
Additional workforce bills include SB 123- Unemployment Compensation, authored by Senator Scott Alexander (R - Muncie), reduced the maximum amount of regular unemployment benefits. Employers pay into an Unemployment Insurance Fund, which provides benefits. An employer’s UI rate is based on several variables, but one of the most significant is the number of workers who receive UI benefits. Seasonal industries pay more than non-seasonal industries because their workers use UI benefits. The UI fund must always be solvent, and if it ever becomes insolvent, statutory countermeasures are triggered to bring the fund back to solvency, including increased UI rates and decreased benefits. Indiana’s fund is solvent. The author hoped to disincentivize unemployed workers from remaining unemployed instead of filling open jobs. The bill would have exacerbated the problem it intended to address—finding workers to fill unfilled jobs—for seasonal employers. They would be unable to find employees when the next hiring season opens. It was heard initially, but the Senate Pensions and Labor Chair, Sen. Linda (cont. on following page)
Rogers (R - Granger) opted not to take a vote, and it died.
(cont. from previous page)
During the interim, IOMA will be involved in conversations related to these and other pieces of legislation to ensure the nursery and landscape industries continue to have a seat at the table when policy that impacts our industry is being developed or contemplated.

Creating Beautiful Outdoor Spaces, Together
We’re honored to be featured in the Indiana Nursery & Landscape Association newsletter and to share a closer look at who we are, what we do, and why we’re proud to be part of Indiana’s growing green industry. Our team is made up of designers, builders, project managers, and craftsmen who care deeply about creating outdoor spaces that last. Just as important, we care about the people we build them for and the professionals we build them with.
Together, our two companies, Vive Exterior Design and Artisan Outdoor Craftsman, serve different but complementary roles in the outdoor space industry. Vive focuses on full-service outdoor living design and construction. Artisan was created to support other landscape professionals by offering high-quality deck and structure builds without overlap in services. Both teams are rooted in collaboration, craftsmanship, and doi ng things the right way.
The Evolution of Vive Exterior Design
Vive Exterior Design was founded in 2008 by Ryan Coyle, who started the company in a small office in downtown Noblesville. In those early days, Ryan wore all the hats: designer, project manager, and everything in between. He saw an opportunity to design and build outdoor spaces that are both functional and beautiful, while delivering a level of professionalism and care that clients can rely on.
What began as a one-person operation has grown into a full-service team of designers, project managers, skilled tradespeople, and support staff who all share the same mindset: do great work, treat people well, and stand by what you build.
From the beginning, our work has been driven by listening to what people want out of their outdoor spaces and making that a reality through good design and solid execution. Over the years, we've expanded our services to include pools, patios, lighting, planting, and maintenance, but our focus has remained the same: create outdoor spaces that work for the way people live.
Our growth has been organic, fueled by referrals, repeat clients, and strong partnerships with suppliers and fellow professionals in the industry. Every project is an opportunity to do something meaningful for someone else, and we don’t take that lightly.
Why We Created Artisan Outdoor Craftsman
As Vive grew and we collaborated with more landscape professionals, we started to hear a recurring theme. Many of our peers needed a dependable partner to handle decks, porches, and outdoor structures but didn’t feel comfortable outsourcing to a company that also offered landscaping. We understood that hesitation and wanted to offer a solution that respected those boundaries.
In 2017, we launched Artisan Outdoor Craftsman as a standalone company, focused entirely on outdoor structures. Artisan was built to support the professionals who are already shaping the outdoor space. Whether we’re brought in just to build or to help design from the beginning, our goal is to make the process easier and more efficient for everyone involved.
Artisan specializes in custom decks, porches, pavilions, pergolas, arbors, and pool houses. If a partner needs help designing a deck or structure to fit into the larger project, we’re happy to assist. We also handle permitting and project coordination so that you and your clients don’t have to worry about the details.
Artisan’s role is simple: we build the structure so you can focus on the rest of the space. We respect the design intent, the project timeline, and the relationships already in place. We’re here to be a dependable extension of your team by being professional, responsive, and committed to quality from start to finish.
Why INLA Matters to Us
Both Vive and Artisan have benefited greatly from being part of the Indiana Nursery & Landscape Association. INLA is more than just an organization; it’s a professional community that helps raise the bar for everyone in this industry. Through INLA, we’ve connected with like-minded companies, gained access to valuable resources, and built relationships that have shaped the way we do business.
We believe that continuing education, strong ethics, and collaboration are essential to the long-term health of Indiana’s green industry. INLA brings all of that together. Whether it’s through events, advocacy, or just sharing ideas across companies, being part of this association helps all of us improve.
We’re grateful to be members and proud to contribute in whatever way we can.
INLA Awards & Project Highlights
We’re proud to have our work recognized by the Indiana Nursery & Landscape Association. Over the past two years, our team has earned six INLA awards. This recognition reflects our commitment to quality, creativity, and collaboration across a wide range of project types. Here are two of our most recent award-winning projects.
Special Projects Award
This project brought new life to a 30-year-old property on Geist Reservoir, where the existing pool and deck had deteriorated and no longer met code. The challenge was not just restoring what was there, but completely rethinking how the upper and lower decks, screen porch, and steep elevation could work together. We created a seamless, cohesive space that feels like it has always belonged to the home using 50-year composite decking, board and batten skirting, StoneDek, and synthetic turf to create both durabilit and livability. From the water, the transformation is dramatic. At night, subtle deck lighting brings it to life, creating a warm and welcoming space the homeowners and their family now fully enjoy.
Residential Hardscape Design/Build Under $50,000
Let’s Connect
Working within tight easement restrictions, we were tasked with designing a modern outdoor living space that maximized every square foot. The result features a compact fiberglass pool, a cantilevered composite deck, and a bold modern pergola with suspended joists for a striking visual detail. A sleek, linear double-sided fireplace adds both warmth and an open view, while gradient-patterned hex pavers and subtle lighting make the space come alive at night. The project balances form and function with a clean, modern design that reflects the homeowners’ vision and makes the most of a compact site.
We’re thankful for the opportunity to share more about who we are and what we do. If you're a landscape contractor, designer, or builder looking for a structure partner you can count on, we’d love to connect. Artisan is here to support your projects with professionalism, craftsmanship, and a clear respect for the work you do. You can find both Vive and Artisan on all major social media platforms, where we regularly share project updates, behind-the-scenes insights, and team highlights. To our fellow INLA members: thank you for everything you do to move this industry forward. We’re glad to be in it with you.
Article by Eric Biddinger - Nursery Inspector & Compliance Officer
As if boxwood blight (Calonectria pseudonaviculata) isn’t enough to worry about, there is another emerging threat to the genus Buxus – the box tree moth (BTM) (Cydalima perspectalis). This critter has marched across Europe decimating wild and ornamental boxwoods. It was found in Toronto, Ontario, Canada in 2018 and introduced to the United States in 2021. Understanding BTM now will allow for early detection, prevent the spread of this pest, and improve management if it is detected in Indiana.
DISTRIBUTION
A native to Asia, BTM was introduced into Germany around 2006. Aided by the nursery trade and finding a home in Europe’s native boxwoods, it has spread across the European continent. Found in Toronto, Canada in 2018 this insect has now been transported through nursery stock to facilities in throughout the United States. Since then, BTM has been identified as established and quarantined in New York, Massachusetts, Delaware, Ohio and Michigan. While so far BTM has not been found in Indiana, it is well positioned to be a threat to Hoosier landscapes.
DESCRIPTION
BTM has a typical moth lifecycle with four stages – egg, caterpillar, pupa, and adult. The pale-yellow eggs are laid in overlapping stacks of five to twenty on the undersides of boxwood leaves. After three days of development, caterpillars will hatch from the eggs. The caterpillars can grow up to 1.5 inches in length and are green with black, yellow, and white stripes, and black spots. The head of the caterpillar is shiny black and the body has fine hairs.
These caterpillars leave behind extensive webbing created to protect them as they consume the leaves of the plant.
After feeding for about 14 days, caterpillars form pupae which take another 14 days to mature. Most adults are white with a brown border, though a small percentage appear as all brown with white “commas” on the forewing.
In its native range of Eastern Asia, BTM has between one and five generations per year depending on latitude and local weather. In Indiana, two to three generations per year are likely.
DAMAGE
BTM caterpillars feed on all Buxus species. Euonymus and Ilex have also been reported as hosts in its native range. The young caterpillars feed on the undersides of leaves creating a peeled appearance. As caterpillars grow, they will eventually consume the entire leaf leaving only the mid rib. While boxwoods can often recover if damage is limited to defoliation, in heavier infestations caterpillars will strip branches of bark, resulting in plant death. In Europe, BTM combined with boxwood blight has created devastating levels of destruction in landscapes and wild plantings of boxwood.
SCOUTING
With no native host plants in North America, the spread of BTM will be likely restricted to landscapes and nursery

pathways. Therefore, careful inspection of boxwood material brought in from other locations will be critical in preventing the introduction and spread of this insect. Populations may be suppressed by regular insecticide treatments in the nursery of origin and begin to express signs of infestation upon planting in the landscape or when regular insecticide treatments are not conducted.

Be on the lookout for quick defoliation of boxwoods and webbing on leaves and branches. Observing caterpillars on boxwood always warrants a closer inspection as BTM is one of the only caterpillars that feeds on this plant. BTM overwinters as larva nestled between leaveswebbed together. They will start to emerge and feed again when temperatures reach around 50⁰F. Look for caterpillars in early or mid-spring and again in late-May and June.
Careful examination of boxwood foliage will be required to find egg masses. Their yellow color and location on the undersides of the leaves makes them difficult to locate.
Capable of moving up to six miles per year, adult moths are considered strong flyers. Due to a lack host material in rural and natural areas, they are most likely to be found in the vicinity of landscapes or nurseries containing boxwood material. Pheromone traps to monitor for adult moths are available. The Indiana DNR has deployed these traps in recent years and will continue to do so throughout the state.
If a small population is found, hand picking the caterpillars may be the most effective means of control. Controls such as horticultural oils and soaps, Bt, and Spinosad should work on young BTM caterpillars. Broad spectrum pesticides effective on other Lepidoptera species in ornamentals are also likely to offer control. Adequate coverage of the inside canopy and on the undersides of the leaves is critical with these products as that is where larva will be feeding. As always, please read and follow all pesticide labels as the label is the law.
As this is a relatively new pest, research is ongoing. Mating disruption treatments and biological controls have shown some promise as future management tools for BTM. However, in the case of all invasive species, eradication, exclusion, and prevention is still the best practice.
BTM is an insect of regulatory importance. To report a suspected find of BTM, please contact the Indiana Department of Natural Resources, Division of Entomology and Plant Pathology at 1-866-NOEXOTIC or DEPP@dnr.in.gov. Or you may contact your local Nursery inspector whose contact information can be found at the following website https://www.in.gov/dnr/entomology/files/ep-Inspector_Territories.pdf

George Brenn’s IAH Study Guide
George Brenn, MIAH, IAH Committee Chair and Editor, created this study guide to help teach the material covered in the IAH Manual. His intention was to assist those trying to master the subjects within the manual.
The new IAH Chapter 15, authored by Dr. Janna Beckerman and Dr. Cliff Sadof, describes the basic process of diagnosing plant problems. Proper plant health diagnosis involves evaluating fragments of information along with critical, open-minded thinking to develop well-reasoned conclusions and solutions.
This is a step-by-step process that involves:
Proper host identification Determination of problem Process of elimination
Observation of SYMPTOMS Identification of SIGNS Determine nature of problem
Proper Host Identification – essential to ID host plant for successful diagnosis (many genera known as Cedars)
Determination of Problem – is problem normal or abnormal? (e.g. normal Autumn needle drop of Pines or Taxodium)
Process of Elimination – certain plants are associated with common problems (e.g. Maples do not get EAB)
Define the SYMPTOMS – SYMPTOMS are the changes in appearance, growth or development in response to a problem. Symptoms reveal a disruption in normal plant function. Often, plants respond the same way to different problems, thus, diagnosis based only on 1 or 2 symptoms may be inaccurate
** Whenever possible, examine the ROOTS of the affected plant to observe and gather relevant info.
Identify SIGNS – SIGNS are evidence of the biologic agents of plant disease. Common signs include: Presence of insects or excrement Frass Fungal mycelia Bacterial ooze (see Ch15; pg7)
Determine Nature of Problem – This is when you use your smartphone and the Purdue Plant Doctor apps.
Distinguishing Between ABIOTIC and BIOTIC Agents – must assess Damage Pattern Distribution and Period of Time for Damage Development
ABIOTIC Diseases are caused by non-infectious agents such as people or the environment.
SYMPTOMS develop rapidly and are usually not progressive. >70% of plant health issues are Abiotic.
BIOTIC Diseases are abnormal conditions of a plant caused by living microorganisms. Biotic disorders are mainly host-specific (e.g. Verticillium Wilt on a Maple will not cause wilt on a White Pine)
Most common Abiotic Diseases in landscapes are caused by ignorance of & abuse by people (PPD’s)
Distinguishing Between Foliar Problems – Foliar problems rarely result in plant death, but are the most obvious. Many root & stem problems are first visible as foliar damage.
Entire or Major Portion of Top is most often related to a ROOT problem. (see Ch15; pg14)
Stem Girdling from rope or twine on rootball, plant tags, OR from ‘Weedeater Disease’ causes vascular disruption
(continued on page 25)
GEORGE BRENN'S IAH STUDY GUIDE (CONT.)
Sudden Decline is usually the result of ABIOTIC disorders (Ch15; pg15)
Physiological Disorder – e.g. Summer leaf drop in response to drought (Ch15; pg16)
Multiple Branch Death is usually root or vascular related (e.g. Verticillium) (Ch15; pg17) **Fireblight is a BIOTIC disorder (Ch15; pg18) but symptoms occur very rapidly
The Degree of a Plant’s RESISTANCE can change over time, as can the resistance of a pathogen to a pesticide
Single Branch Dying can be either Biotic or Abiotic (Ch15; pg19}
Foliar Injury – Chemical injury of foliage from phytotoxic pesticides, herbicides, etc., can cause leaf spotting, curling, cupping or twisting or other distortions of foliage (Ch15; pg20)
Foliar Problems in Conifers (Ch15; pg21-22) Need to observe if damage is on only leaves (needles) of a specific growth period (e.g. normal autumn needle drop on Pines and Arborvitaes, etc.)
Foliar Symptoms can indicate root problems (Ch15; pg23)
Vascular Wilt (Ch15; pg24) can be caused by excess salts, errant pH, herbicide uptake thru roots (Ch15; pg24)
Distinguishing Between Pathogens and Insect / Mite Damage requires OBSERVATION
SYMPTOMS = changes in appearance, growth or development. SIGNS = evidence of the biologic agent causing damage
The Combination of both Symptoms and Signs is required for preliminary distinction between pathogens & insects
SYMPTONS and SIGNS of FOLIAR PROBLEMS
• Is entire leaf or only portions of leaf consumed? (Ch15; pg27) Are portions distinct? (Ch15; pg28 + Ch8;pg 41)
• Is webbing, frass or excrement present? (Ch15; pg27)
• Powdery Mildew (Ch15; pg29) There are many species of Powdery Mildew, but they are Host Specific
• Galls (Crown Gall, Rust Gall, Black Knot) (Ch15; pg50)
• Blights (Ch15; pg51-52)
SYMPTOMS and SIGNS of ROOT PROBLEMS
• BIOTIC Problems – Most root problems are Biotic, but are often misdiagnosed. Many soil-borne pathogens are Anaerobic (= living in lack of Oxygen). These prosper in poorly drained soils (Ch15; pg42)
(continued on page 26)
GEORGE BRENN'S IAH STUDY GUIDE (CONT.)
& NEW IAHS
• Root Feeders – larval stage of Beetles (e.g. Jap Beetle or Rose Chafer Grubs), Weevils (e.g. Black Vine Weevil) or Moths (e.g. Sod Webworm) (Ch15; pg42 + Ch8; pg 54)
• Nematodes = microscopic roundworms. Root Knot Nematodes cause galls to develop at feeding sites (Ch15; pg53)
• Declines can be sudden or gradual (Ch15; pg15)

Schneider Nursery Hosts Women of the Green Industry
On June 19th, 2025, Schneider Nursery in Seymour, Indiana graciously opened its doors to host an enriching and inspiring event for the Women of the Green Industry. The event offered a unique opportunity for attendees to learn about large-scale nursery operations, connect with fellow professionals, and enjoy a day of networking and education in a beautiful setting.
Attendees arrived from across the state, representing a wide range of roles within the green industry—from landscape designers and nursery managers to students and garden center leaders. The event began with a welcoming lunch, allowing participants to casually network and reconnect with colleagues and peers.
Following lunch, the group gathered to hear about the history and growth of Schneider Nursery, a family-owned operation with deep roots in Indiana’s horticultural community. Jill Glover led the discussion, offering insight into the evolution of the business, the scope of its retail and wholesale operations, and the company’s commitment to quality plant production and customer service.
Attendees were then given a guided tour of the on-site garden center, led by Glover. This portion of the tour sparked thoughtful discussion among attendees, many of whom work in or with retail garden centers and appreciated the opportunity to share ideas and best practices.
The tour continued with a walk down to the production fields, where Jill Glover was joined by Ben Maschino and Grant Schneider. Together, they provided an in-depth overview of the nursery’s growing methods, inventory management, and production strategies for supplying high-quality plant material to a diverse clientele.
Participants had the opportunity to ask questions throughout the tour, leading to valuable conversations about everything from pruning techniques and weed control to marketing trends and workforce development.
In addition to members of the Women of the Green Industry, several board members of the Indiana Nursery and Landscape Association (INLA) were in attendance, showing their support for the organization and its mission to elevate and empower women working in the Green Industry.
The event concluded with informal networking, giving attendees time to reflect on the tour, exchange contact information, and discuss future collaborations. Many participants expressed gratitude for the opportunity to visit a top-tier nursery and left feeling inspired and energized about their roles in the green industry.
