    Growing Your Best Begonias ft. Syngenta’s Brian Krug & Jamie Gibson

    Syngenta Flowers’ Dr. Brian Krug and Dr. Jamie Gibson join Tech On Demand host Bill Calkins to discuss the exciting world of begonias, focusing on both vegetative and seed varieties. They explore the latest introductions, production best practices and the importance of lighting and PGRs in growing high-quality begonias. The discussion highlights the growing popularity of begonias in gardening and their versatility in various applications. One of the top new introductions at California Spring Trials in 2025 was iCandy, a vegetative series of hybrid begonias for quarts and up—with double flowers and dark foliage—and Brian spends time detailing production best practices before moving on to other vegetative series including Adora (perfect for baskets), Birthday Bash (more traditional, waxy foliage and double flowers) and Florencio (a boliviensis hybrid). Then Jamie goes through tips and tricks for producing a few newer seed-raised series from Syngenta including Bossa Nova (boliviensis types), Bionic (large, interspecific landscape type) Tophat (early-to-flower interspecifics with huge flowers) and Limitless (tuberous). For each series, Brian and Jamie discuss production recommendations from propagation through finish—including lighting protocols, PGR regimes, temperature requirements and much more. Strategies to reduce the risk of blind cuttings are also shared. WATCH THE VIDEO!

    Perfecting Pentas Production ft. Syngenta’s Dr. Jamie Gibson

    Syngenta Flowers’ Dr. Jamie Gibson joins Tech On Demand host Bill Calkins to discuss best practices for growing high quality pentas—both seed and vegetative varieties. As Jamie said multiple times, one of the biggest keys to getting the most out of pentas is keeping them warm. But there’s a lot more to maximizing production and there are nuances to understand with vegetative types, like Syngenta’s Starcluster and Starcluster Cascades, as well as the seed range, which includes Beehive, BeeBright and HoneyCluster. Jamie and Bill kick off the discussion with vegetative pentas in the Syngenta range—Starcluster and Starcluster Cascade. Jamie calls out some key attributes like huge umbels, thick foliage and major pollinator attraction before digging into propagation from URCs or callused cuttings. If you’re concerned about propagating pentas from cuttings, a good idea might be to bring in liners and just finish them in about 8 weeks or even start from enhanced, larger liners to cut off a few more weeks in production. Another tip is for growers in Northern climates to bring in cuttings after week 6 to reduce the risk of cold-chain damage. Remember, it’s a heat loving crop and receiving vegetative pentas after week 6 still gives plenty of time to finish the crop for Mother’s Day. Jamie follows production through finish and even teaches Bill a new term, “Xanthophyll,” the yellow pigmentation that sometimes makes pentas roots look like they’re struggling even though they’re completely healthy. Then Jamie and Bill turn the page and start on the seed-raised types. Jamie suggests buying in plugs from experienced pentas propagators because nailing pentas plug production can be quite tricky. Transplanted plugs still need to be grown warm (66-75F), and it’s recommended to consistently test pH and make sure it stays above 6.2 and also consider adding calcium nitrate to keep the pH up and tone the crop. In terms of positioning the seed-raised series from Syngenta, Jamie suggests BeeBright for packs and smaller pots, HoneyCluster for quarts and Beehive for baskets.

    Biosolutions for Ornamental Propagation ft. Koppert’s Kristen Fowler

    This Tech On Demand podcast episode is all about propagation, biosolutions and starting your crops strong from the earliest stages. Host Bill Calkins is joined by Kristen Fowler, a technical sales consultant with Koppert who not only works with propagators but spent many years in leading propagation greenhouses as a grower—so she’s no stranger to the importance of optimizing plants at the most critical times during production.   In this episode Bill and Kristen discuss the importance of cleanliness before and after young plants are received, tips for assessing cuttings when they arrive at your greenhouse (you don’t want to push poor product onto your benches), consistent scouting and working with suppliers to understand what’s been applied to young plants before they come through your door. They also dig deep into what biological products can be used during each propagation stage (some products work well under mist, and some do not) and a roadmap to follow for protection when roots emerge, mitigating insect and mite pest pressure early on and biosolutions to apply at the time of transplant. With such a strong understanding of the propagation environment, Kristen is keenly aware that the best way to introduce many biological strategies and hybrid approaches is to work within existing propagation processes and not change too many protocols—think tank mixes, boom applications and different options for different systems.   RESOURCES: Koppert U.S. Koppert Consultants & Locations Koppert Contact Koppert Crop Protection Products Koppert’s Side Effects Guide App 2025 GrowerTalks Biosolutions Guide 2026 GrowerTalks Insecticide, Miticide & Fungicide Guide (English) 2026 GrowerTalks Insecticide, Miticide & Fungicide Guide (Spanish)

    Grow Your Sustainable Future with Proven Winners

    Sustainability and environmental responsibility are high on the priority list for the Proven Winners team and their partners. Their new Eco+ plastic-free and industrial compostable pots are a key part of this plant powered package. Host Bill Calkins caught up with Proven Winners’ director of sales, Dave Konsoer and Danny Mishek, president of VistaTek—the award-winning manufacturing company behind the new pots and other plant-based, compostable products making their way into many industries. Danny, Dave and Bill discussed all aspects of the new packaging from manufacturing and trialing to ensure integrity in greenhouse environments to seamless integration into crop production systems and the strong, branded retail presence for which Proven Winners is known. Dave clearly explains the reasons Proven Winners invested in the move to sustainable packaging and Danny articulated why a zero-plastic approach is not only responsible but becoming necessary due to new regulations being implemented in many states very soon. Of course, the pots went through many iterations in development and functionality in greenhouse production and retail settings was non-negotiable and Dave stated there are no changes to how crops are grown in Eco+ pots and the brand messaging remains crisp and clear on the plastic-free material. Danny explained regulatory changes coming quickly in many states and why bio-based materials and plastic-free pots like Proven Winners’ Eco+ will help growers stay ahead of “extended producer responsibility” laws. Plus, as Dave explained, consumers clearly want responsible packaging and look to Proven Winners as a leader in the gardening space. The company’s social media pages for gardeners are filled with positive comments about the new plastic-free packaging. There’s so much fantastic information in this podcast and excellent discussion around the topic of sustainability. It’s steeped in real-world horticultural knowledge of supply chains, price sensitivity, production situations, tolerance for change and future plans. You really have to listen all the way to the end because the ideas and info just keep coming.
