Warning: You’re going to hear the word SEED a lot in the next half hour or so, because our guest this episode is Josh Kirschenbaum, the seed supply manager at Ball Seed Company. He’s a seed guy all the way. In previous roles, Josh was PanAmerican Seed’s business and portfolio manager for the company’s vegetable lineup and before that was product development director at Territorial Seed Company in Oregon. Here’s what you can expect from host Bill Calkins and Josh this episode: Their shared fascination with the new OPEX Perfect Pick machine Ball introduced earlier this year. Josh describes it as a climate-controlled vending machine for seed packets that can pull 20 orders at a time, resulting in speedy service and increased accuracy in order fulfillment. (Check out the video and article link in the resources below to see the machine in action.) Bill challenged Josh to come up with three reasons why seed solves problems and why it’s still a preferred way to produce crops. Josh explains the economic benefits, why flexibility and efficiency are optimized when starting from seeds or plugs and finally the amazing innovation and quality of genetics available from seed. Throughout the conversation, Bill and Josh touch on many more aspects of seed crops that have been at the core of Ball’s business for more than a century. Josh discusses the global nature of our industry, how innovative breeding drives our future, the importance of quality seed in large-scale plug production and the legacy seed has in horticulture.

This episode includes critical information for both nursery and greenhouse producers! To discuss this episode’s topic, host Bill Calkins was joined by a fantastic guest from Envu—Dr. Janna Beckerman—who’s an experienced plant pathologist at heart and wanted to discuss three key diseases commonly encountered in greenhouse and nursery crop production. Conveniently for the podcast title, these diseases begin with the letters A, B and C—anthracnose, Botrytis and cercospora. In this episode, the conversation starts with a brief recap of some diseases Dr. Beckerman saw a lot of in the spring, like rusts and Pythium and then the conversation moved quickly to the topic at hand—foliar diseases. Bill and Janna took the three ABCs in order talking through the main crops impacted by each one, symptoms to watch for and control methods. Although Dr. Beckerman mentioned one of Envu’s flagship fungicides, Broadform (a unique chemical class with two modes of action to control more than 50 pathogens), her rotation recommendations and application best practices were extremely in-depth and user-friendly. She also went through strategies to mitigate the risk from these three diseases using good sanitation practices and greenhouse and nursery environmental management. Bill and Janna closed out the conversation with the importance of resistance management—a topic that cannot be overstated. Keeping our toolboxes full and giving all growers the best chance for controlling diseases (and insect/mite pests) requires diligence and intelligent approaches to chemical rotation and application. You’ll want to listen all the way to the end of this episode, because Dr. Beckerman is a true expert and offers countless tips and tricks to help you and your production team up the game season after season.

Host Bill Calkins asked Jaime Kedrowski (Marketing Manager at Ball Seed Company) to join him for a discussion about the short-term future of our industry. This conversation was recorded live at the 2025 Ball Seed Customer Days open house event in West Chicago, IL. For this episode, Bill had three “big ideas” that he introduced to Jaime one at a time to find out what she had to say about them (and if she had any even bigger ideas or approaches). There are no right answers and neither Jaime or Bill own a functional crystal ball. But the goal of this discussion was to share ideas to ponder and potential directions to steer as our industry enters a new era. Topics discussed:

In this episode of the Tech On Demand podcast, brought to you by GrowerTalks, host Bill Calkins sat down with SePRO’s Technical Development Manager (and PestTalks e-newsletter editor) JC Chong to discuss plant growth regulators. PGRs are critical for greenhouse professionals but really haven’t been covered much on the podcast. Now’s the time! JC and Bill start off with a conversation about what PGRs are and what they do before jumping into a few specific products, including SePRO’s Topflor and A-Rest. Topflor is a gibberellic acid biosynthesis inhibitor (Class B)—active ingredient Flurprimidol. It offers some unique benefits in production, which JC covers in an informational way. JC outlines crops that respond particularly well (and some that don’t) and what you can expect from crops treated with the product. JC also explains some of the more common rates and application methods and a handy tool from SePRO to take a lot of the guesswork out of PGR application. JC is a researcher and has worked with the SePRO team and growers across North America to better use PGRs to achieve a variety of goals and has a lot of practical information to share. You’ll want to listen all the way to the end of this episode because when Bill and JC chat, you never know what to expect! WATCH THE VIDEO VERSION!

PAYING FOR THAT EFFICIENCY UPGRADE FROM THE SUMMER 2025 ISSUE OF INSIDE GROWER MAGAZINE WRITTEN BY DAVID KUACK NARRATED BY BILL CALKINS EXCERPT: When it comes to lowering operating costs for controlled environment growers, energy and labor are top of mind. The cost of labor is expected to continue to increase as the availability, hiring and retention of reliable workers becomes more challenging. The cost of energy—regardless of whether it’s electricity, natural gas, fuel oil or propane—will also likely continue to increase. Growers, regardless of where they’re located, are expected to have to deal with increasing weather unpredictability. For these reasons, more growers are looking for ways to improve the energy efficiency of their facilities. Read the Digital Edition: https://www.ballpublishing.com/magazine/ig_25_05/index.aspx

GETTING THE MOST OUT OF TRIALS FROM THE JUNE 2025 ISSUE OF GREEN PROFIT MAGAZINE WRITTEN BY DYLAN SEDMAK NARRATED BY BILL CALKINS EXCERPT: Modern day variety trials—side-by-side comparisons of primarily annuals (along with some perennials, vegetables and even woodies)—take place across an array of institutions in North America.

This episode is a bit different—because it’s a live recording from a panel moderated by host Bill Calkins at the Darwin Perennials Day event in The Gardens at Ball on June 18, 2025. The audio quality is not as good as you’re used to hearing from this podcast, because it’s pulling from microphones in a tent with lunch being served and hundreds of growers in the background chatting about the plants they saw that morning and meetings with more than 30 leading perennial suppliers in the Ball Seed network. That said, the panelists were excellent, and the content is fantastic. The topic was error correction—common challenges in perennial production that can be easily fixed to avoid running into the same issues year after year. The panel included Chris Fifo from Darwin and PanAmerican Perennials, Drew Koschmann from Walters Gardens and Nathan Jahnke from Ball Seed Technical Services. Some of the frequent pitfalls discussed included best practices for overwintering and bulking perennials, why input selection is critical, evaluating perennial plug and liner quality, managing tough environmental conditions and new research into no-pinch production strategies. We also solicited questions from the crowd and covered about 10 of them before closing. If you missed this year’s event, that’s OK. Darwin hosts it every year! Mark Wednesday June 17, 2026, on your calendar and come check out the Gardens at Ball with thousands of perennial plants in bloom.

This episode includes critical information for both nursery and greenhouse producers! You may or may not know exactly how much time, labor and ultimately money you spend each year managing weeds in outdoor and indoor production, but chances are it’s a lot. If you don’t have protocols and strategies in place for weed control, that can lead to even bigger issues. To discuss this topic, host Bill Calkins is joined by two guests from Envu—Dr. Janna Beckerman and Steve Larson—to talk through best management practices related to weed control and specifically the use of Marengo, a preemergence herbicide that not only controls more than 90 weeds (including broadleaf weeds, grasses and sedge) but also clocks in with residual activity for up to 8 months. It’s labeled for use inside greenhouses and can be a key player in your greenhouse sanitation lineup. Envu’s Janna and Steve have decades of experience in our industry and bring a lot to the table when it comes to the science behind greenhouse and nursery production, as well as the real-world application of products and strategies. When it comes to weed control in production settings, Janna said it best—the greatest cost is the cost of neglect. In this episode, the conversation starts with an overview of Envu’s history and innovative product range before quickly moving into weed control in nursery and greenhouse production. From regionality and seasonality of weeds and their impact to application strategies for preemergence herbicides and keys to safe use, there’s a lot to discuss. And with its residual staying power, wide range of weeds controlled and labeled indoor applications, Marengo (granular and liquid) is a product with benefits for just about every type of greenhouse and nursery operation. You’ll want to listen all the way to the end of this episode to hear all the tips, tricks, research and anecdotal success stories the Envu team had to share!

This Tech On Demand podcast episode is all about fall control, integrated pest management and implementing biocontrol strategies that work. Host Bill Calkins is joined by Phil Gerry, a Technical Sales Consultant for the Northeast Region covering six states for Koppert. Koppert is a global market leader specializing in biological crop protection and team members have joined the podcast before covering biological IPM for spring crops and strategies for hybrid and truly integrated strategies. Phil was lead grower for large nurseries and greenhouses in the Northeast and Northwest before joining Koppert in 2021 and brings an incredible amount of practical knowledge and creative strategies to the topic of managing key pests in garden mum and poinsettia production. In this episode Bill and Phil discuss the spring production season before jumping into the main topic—IPM for crops produced in summer for fall and holiday sales. Phil explains the importance of understanding the compatibility of biological controls and traditional chemistries, as well as why it’s critical to define what success looks like for your greenhouse or nursery before integrating biocontrols. As he reiterated, when making a move to bio-based approaches, it’s best to start slowly—choose one crop or one pest and hone skills before moving on to a more comprehensive plan. When it comes to biological controls for garden mums, indoor versus outdoor production must be considered and beginning applications in propagation is the best approach for various reasons Phill addressed. Key pests discussed include aphids, thrips, fungus gnats, whiteflies and spider mites. Moving on to poinsettias, of course the main pests (whiteflies and spider mites) require diligence, scouting and early preventative controls and Phil explained some of his go-to tactics. Be sure to listen all the way to the end of this discussion because these notes barely scratch the surface!

HOW MUCH DOES A GREENHOUSE PROJECT REALLY COST? FROM THE APRIL 2025 ISSUE OF GROWERTALKS MAGAZINE WRITTEN BY CHRIS BEYTES NARRATED BY BILL CALKINS EXCERPT: Anyone who’s completed a greenhouse project knows that a lot more goes into it than you might think. But how much, exactly, as a percentage of the total cost? We asked three experts—Paul Golden with Prospiant, Matt Stuppy with Stuppy Greenhouses and Jeff Warschauer with Rovero North America—to help us with the math. It was a challenge because every site and every project is unique, and their usual answer is, “It depends,” but we forced them to break it down into key components and what percent of the project each might be. The figures below are minimums you’ll need for each category; in some cases (like site work), it could be much higher.

Forcing perennials out of winter dormancy and into bloom for spring and summer sales isn’t a new concept for most growers, but growth in the perennial market has inspired a lot of folks to add perennials to their mix and there’s been plenty of research done to update protocols for breaking dormancy. Because of this, Tech On Demand host Bill Calkins wanted to have a quick discussion with perennial plant guru Chris Fifo (from Darwin Perennials) to make sure everyone is on the same page when it comes to waking perennials up this spring. In this concise tech tip-style conversation Bill and Chris discuss the “traditional method” of forcing perennials and the “new-school way,” which results in better uniformity and reduced losses. Then Chris explains tactics any grower can use to force long-day perennials using an extension cord and a string of lightbulbs, as well as offering suggestions for reducing the risk of disease when perennials are being forced to wake up in early spring. The bottom line: It’s not as difficult as it sounds—warming them up and basic night interruption will work wonders on your perennial crop this spring.

For this installment, Lorentina McKoy, the North American sales and product rep for Suntory Flowers, joins host Bill Calkins to talk about Princettia—the unique poinsettia assortment from Suntory that looks different than traditional holiday poinsettias because it’s bred to be different. This opens up some unique uses and retail specs and also requires some production nuances. Because breeding on Princettia is quite active, a whole new range of colors and patterns has come to market in the past couple years, as well as a new sub-series with a more vigorous habit. In this episode, Lorentina offers tips and trick to produce Princettias to their full potential, some ways she’s seen them marketed and sold around the world, why the fact they’re a true “family” of genetics is important and much more. Although this episode is focused on one crop, Lorentina and Bill actually get into many different topics—from an early-Spring outlook and consumer trends to retail garden center tips and strategies to sell premium products. You’ll want to listen all the way to the end because this episode closes with some other top picks in the Suntory range of new varieties for 2026.

One of the greenhouse pests growers have been dealing with more and more recently is broad mite. This specific mite pest is extremely challenging to diagnose and treat and can wreak havoc on a very wide range of crops across multiple seasons. Host Bill Calkins is joined by well-respected professor and extension specialist in horticultural entomology at Kansas State University, Dr. Raymond Cloyd, to discuss this pest—from susceptible crops and theories why broad mites are on the rise to symptoms and identification. Dr. Cloyd then shared a bit about the pest itself and strategies to minimize the risk of losing crops due to broad mites and methods for control. Once broad mites were covered, Bill asked Dr. Cloyd about Lewis mites (based on challenges with this pest on poinsettia crops in 2024), and the episode closed with the importance of sanitation, diligent scouting and IPM protocols during spring production. You’ll want to listen all the way to the end of this episode and share it with your entire production staff.
