4 Questions for Marcus, a Landscape Business Manager
2026/10/26
Throughout 2026, host Bill Calkins has been catching up with different people in the professional horticulture space and find out a little bit about their careers, passions, journeys in the world of plants and much more. He sent each potential guest a list of 12 questions and they picked four to answer and discuss.
This episode, Bill is joined by his friend Marcus Jansen, the new Landscape Business Manager for Ball Seed and a fascinating guy with deep roots in horticulture—from 4-H and FFA to Iowa State hort degrees and multiple internships with leading green industry businesses. Eventually his path led him to Ball, where he spent 5 years with PanAmerican Seed and is now leading a major, strategic initiative with landscape. But the corporate side of Marcus is just one facet of his industry life. He’s also active in many organizations and even leads a “plants and pints” activity at his local brewery.
Marcus brings tons of passion to his roles in our industry and you can’t help but get inspired when he talks plants. Be sure to listen all the way to the end so you don’t miss anything.
Here are the four questions Marcus chose to answer:
Q: What was your first exposure to “horticulture” and how did you feel, react, respond?
Q: If you won the lottery and could start a horticulture business from scratch, what would it be and what would it look like?
Q: What are your top 3 favorite annuals? And perennials?
Q: What advice would you give to a young person considering pursuit of a career in horticulture?

Avoid These 9 Greenhouse Sanitation Mistakes!
2026/10/20
Host Bill Calkins talks with Eric Smith, national sales manager for BioSafe’s horticulture division, about how sanitation, crop protection and water treatment work together as a true IPM strategy. The discussion focuses on practical greenhouse and nursery sanitation and covers some of the most common mistakes growers make and ways to correct them and build a proactive program that protects crops, reduces disease pressure and improves consistency.
Don’t make these mistakes!
Simply “cleaning” your facilities.
Confusing acid and alkaline sanitation chemistries.
Forgetting to sanitize unseen areas (like evaporative cooling systems, roll-up sidewalls, underneath groundcloth, inside pipes, etc.)
Ignoring biofilm in your irrigation lines.
Only sanitizing between crops.
Not focusing on your propagation range.
Only using one application method.
Making common application errors (like rinsing too soon or relying on pressure washing.)
Not being consistent with your sanitation practices.

FIXING THE FLOW: IS YOUR GREENHOUSE DESIGN COSTING YOU MONEY?
FROM THE OCTOBER 2026 ISSUE OF GROWERTALKS MAGAZINE
WRITTEN BY JENNIFER ZURKO
NARRATED BY BILL CALKINS
EXCERPT: When you move into a new home or decide it’s time to refresh one of the rooms, you picture how it’s going to look: the arrangement of the furniture, the paint color you’ll put on the walls, the type of flooring, and the other finishing touches like lighting and wall décor. You envision and coordinate where everything will go, and how the harmonious arrangement will provide your desired spatial balance and foot-traffic flow.
This general thinking can be the same for a greenhouse, too. You want the right equipment and tools to make sure you make the most of the space, and the right environment for successful production. But it takes more time to analyze and study the balance and traffic flow, especially when it comes to moving finished product out the door in the most efficient and cost-effective way possible.

Using Supply Chain Strategy to Deliver OTIF ft. Growscape’s Richard Shapiro
2026/10/07
This episode of the Tech On Demand podcast, brought to you by GrowerTalks magazine breaks down how On Time In Full (OTIF) performance is really the result of months of planning and collaboration, not just the final shipment.
Host Bill Calkins talks with Richard Shapiro, vice president of supply chain operations at Growscape (North American manufacturer and supplier of horticultural containers, planters and garden products), about forecasting, lead times, seasonality and the sales and operations planning process behind reliable fulfillment in horticulture.
Richard also explains how Growscape thinks about sustainability across manufacturing, distribution and transportation—and why stronger collaboration between growers and suppliers creates better outcomes for everyone. As he repeats a few times, “Tell me something I DON’T know!” That’s how improvements are made. And in this day and age of emails and texts, it’s refreshing to hear Richard request that customers pick up the phone and give a call to talk through challenges or discuss forecasts. This is the type of collaboration our industry is built on.
Not only is this episode an extremely transparent look at how a major horticultural supplier navigates a seasonal industry and works with businesses of all shapes and sizes but it’s also packed with sales and operations planning (S&OP) advice and strategy from someone with decades of experience leading businesses and driving results. Richard is truly an expert in this aspect of manufacturing and supply and there’s a lot to learn from him. Be sure to listen all the way to the end!

Nick's Newsletter Tip (Week 39): Cool-Weather Crop Management
2026/09/24
Ball Seed Technical Services Specialist Nick Flax breaks down the key environmental and cultural adjustments your production team should make as temperatures drop. The focus starts with dewpoint management. Warm days followed by cool nights can quickly create condensation inside the greenhouse, increasing the risk of fungal diseases like Botrytis and Pythium. Nick explains practical strategies to stay ahead of humidity, including dehumidification cycles, greenhouse "burping," temperature setpoint adjustments and controller checks.
The discussion also covers crop culture changes that often accompany fall weather. As plants use water more slowly, irrigation practices may need to be adjusted to avoid overly wet conditions. Nick shares tips on irrigation timing, crop spacing, air movement and using objective measurements such as water-by-weight to guide decisions.
Finally, the audio tip reviews some disease prevention strategies for high-risk crops (like poinsettias) and highlights the importance of maintaining a proactive fungicide program as environmental conditions become more favorable for disease development.
Now that you're transitioning from summer to fall production, this week’s tech tip offers practical reminders to help protect crop quality and reduce disease pressure during the season ahead. By now, you’ve realized my man Nick is pretty good at that!

AI for Green Industry Businesses ft. Justin Ragsdale (First Steps, Customer Engagement & What’s Next)
2026/09/16
For episode 273, host Bill Calkins talks with IM Digital’s Justin Ragsdale about how greenhouses, garden centers and nurseries can use AI and other emerging technologies without getting lost in hype. The conversation focuses on practical use cases, from automating repetitive work to improving year-round customer engagement and building stronger digital systems. Justin explains how to think about AI as a tool, not a magic wand, and why the best results come from adding context, data and clear business goals.

There’s a lot covered in this episode. Here are a few of the topics Bill and Justin discussed:
Perhaps the best way to approach AI is as another tool in the toolbox, not as a replacement for business judgment, staff or customer relationships.
A major theme is the importance of context: AI works better when businesses give it clear instructions, business processes, goals, customer information and system access, instead of just asking it to “do stuff.”
The episode walks through simple starting points for AI adoption, including using tools like Claude or Gemini Enterprise for everyday tasks such as email triage, social media responses and creating basic marketing agents.
How your best early wins will come from solving known problems, not trying to make AI predict the future or solve unclear business challenges.
Why customer engagement is a major focus, especially how garden centers can use POS data, marketing platforms, and AI to personalize follow-up based on purchase history, location, and seasonal needs.
For businesses, an early step should be to identify their “source of truth” for customer data, then connect other systems to it so AI can build useful profiles and campaigns.
Labor efficiency comes up as another key opportunity: AI can help train staff, document tribal knowledge, and reduce repetitive admin work so employees can spend more time on the sales floor with customers.
The conversation closes with a look at the future, where the most advanced garden centers will be available across digital channels, in customers’ pockets and responsive 24/7, while still protecting the human expertise that makes garden centers valuable.

Audio Files: What Plants Are Customers Searching For & Where Is Breeding Still Open?
2026/09/11
WHAT PLANTS ARE CUSTOMERS SEARCHING FOR & WHERE IS BREEDING STILL OPEN?
FROM THE SEPTEMBER 2026 ISSUE OF GROWERTALKS MAGAZINE
WRITTEN BY CHI NGUYEN, SETH WANNEMUEHLER AND MIKE SCHNELLE
NARRATED BY BILL CALKINS
EXCERPT: Every breeding program eventually faces the same difficult question: Where should the next five to 10 years of effort go? Grower experience, customer requests and historical sales remain essential, but they mostly describe what’s already known. They may not reveal where consumer attention is building or where the competitive space is already crowded.
A recent HortScience study developed a Breeding Opportunity Index (BOI) to add that missing layer by combining U.S. Google Trends data with U.S. plant patent records. USDA production data provided the geographic context. The goal was to screen genera and traits before committing years of breeding, trial space or licensing resources.

Insect & Disease Issues in Cut Flowers ft. Dave Dowling
2026/09/07
WATCH THE VIDEO PRESENTATION
Pests and diseases can wipe out a cut flower crop fast—but the biggest mistake growers make is waiting too long to notice them. Ball's cut flower specialist Dave Dowling breaks down the pests and diseases that hit cut flower farms hardest, and the scouting habits that can save an entire season before damage becomes irreversible.
Dave spent more than two decades growing cut flowers before moving to the supply side, and he brings that field-tested perspective to everything from low-cost startup advice to the realities of selling top-quality stems. If you're thinking about adding cuts to your operation, or you've already planted them and want to protect your investment, this conversation gives you the practical playbook.
Some of what Dave covers in this 30-minute discussion includes:
How to spot aphids, thrips, Japanese beetles, lily leaf beetles, tarnished plant bugs, spider mites and cabbage moths before they take over
Why certain crops like gladiolas, dahlias, zinnias, lilies, peonies, ranunculus and chrysanthemums are especially vulnerable
What actually works for control, from neem and horticultural oils to beneficial insects, Bt and labeled chemical options
The difference between prevention and rescue, especially when dealing with powdery mildew, Botrytis, root rots and viruses
Why crop rotation, airflow, drainage and relentless scouting matter more than most growers realize
Dave also breaks down the hidden traps that catch new growers off guard, like introducing beneficial insects too late, using Japanese beetle traps in the wrong place or overlooking early damage that won't show up until weeks later—when blooms are ruined and the crop is lost. Dave explains how small decisions at the start of the season can determine whether you harvest a clean, salable crop or lose your crop and your profits.
This is essential listening for greenhouse growers, cut flower farmers and anyone expanding into a new product line without wanting to learn the hard way. If you grow cut flowers for profit, the advice in this episode can help you protect your crop, your customers and your bottom line.

4 Questions for Coy, a Sales Representative
2026/09/02
Throughout 2026, host Bill Calkins has been catching up with different people in the professional horticulture space and find out a little bit about their careers, passions, journeys in the world of plants and much more. He sent each potential guest a list of 12 questions and they picked four to answer and discuss.
This episode, Bill is joined by his friend Coy Butner, a Sales Representative with Ball Seed Company in the Midwest. It’s a fun episode because Coy is not only a fantastic partner to his customers (greenhouses of every size and shape) but also a great storyteller with a long history in horticulture that spans more than three decades and includes owing a retail greenhouse and then as a sales rep for more than 20 years. But Coy didn’t start off in hort, which is where the episode begins.
Coy shares the importance of listening, working with customers to identify challenges and bring solutions, what he looks for in new varieties (and some of his favorite plants like gomphrena, zinnia and echinacea) and how to stay engaged and enthused. He also makes an analogy comparing growing vegetative annuals to raising hogs. You’ve got to hear this!
Here are the four questions Coy chose to answer:
Q: How do you explain our industry to strangers, friends, family?
Q: What are your top 3 favorite annuals? And perennials?
Q: What advice would you give to an industry veteran currently dealing with burnout?
Q: What do you love most about your job?

Maximizing Early Order Programs ft. Envu’s Steve Larson
2026/08/26
Host Bill Calkins was joined for this episode by Steve Larson from Envu. Steve and Bill sat down to chat about something that just about every greenhouse owner and manager deals with each year—but a topic that probably doesn’t get the press it deserves (probably because it doesn’t generate the same level of excitement as new plant varieties ...) But when it comes to saving money and securing the crop protection products needed for a successful season—Early Order Programs (EOPs) are definitely one of the most critical topics.
Steve and Bill talked about the history of EOPs, why growers should be motivated to buy from an EOP, tips for making smart purchase decisions (not over-buying or under-buying) and the importance of leveraging the terms that often come from early order programs.
Steve also discussed Envu’s EOP program, which kicks off on September 1, 2026. Everything you need to know about this program can be found at https://www.us.envu.com/ornamentals/programs - including the EOP calculator Steve mentioned in the podcast.

WRITTEN BY JOHN STANLEY, SID RAISCH & DRIES JANSEN
NARRATED BY BILL CALKINS
EXCERPTS: Your website isn’t a brochure; it’s your store open 24 hours a day and now it’s also your application for AI recommendation. Most importantly, begin with connecting your email, text and every other marketing effort to the customer with the invitation to learn, be inspired and buy. If your customers are arriving at dead ends on your website right now, fix them and make it easy to click to send you money.
Before you sell a single plant online, your shop is already talking. A site with stale photos from two springs ago, no way to buy anything and an “Under Construction” page tells customers loud and clear: “We are not ready for you.” A clean, current online shop with real products, real prices and a “Buy Online, Pick Up In Store” button tells them the opposite: “We’re open for business, we respect your time and we’re ready to serve you right now.”

FROM HOME GARDENS TO MARKET INSIGHTS
FROM THE AUGUST 2026 ISSUE OF GROWERTALKS MAGAZINE
WRITTEN BY CELINA GOMEZ
NARRATED BY BILL CALKINS
EXCERPT: One of the most exciting takeaways from our latest study is the ability to quantify the benefits of gardening on human wellbeing. We often say that plants make people feel better. Now we’re starting to build the data to support that claim. Our findings show measurable improvements in mood, confidence and engagement, all tied to a relatively simple gardening experience. This opens the door for growers and retailers to incorporate wellbeing-focused messaging into their marketing and outreach.

A RESILIENT INDUSTRY REQUIRES MORE THAN BASIC INPUTS
FROM THE JULY 2026 ISSUE OF GROWERTALKS MAGAZINE
WRITTEN BY LAURA BARTH
NARRATED BY BILL CALKINS
EXCERPT: Like any living system, floriculture requires continuous investment to remain healthy, productive and resilient. Research, workforce development, sustainability initiatives and industry collaboration all play important roles in supporting the long-term strength of floriculture, even if their impact isn’t always immediately visible from the greenhouse floor. For 65 years, the American Floral Endowment (AFE) has helped cultivate the floriculture industry through research funding, scholarships, internships and educational resources designed to strengthen the floriculture industry as it continues to grow and evolve—because healthy industries, like healthy crops, don’t happen by accident.
