Air, Electricity, and Insects: A New Recipe for Plant Nutrition?

By Pamela Andrade, University of California, Davis Greenhouse and nursery producers operate under constant pressure to deliver uniform, high-quality plants on predictable production schedules. Whether producing bedding plants, ornamentals, or vegetable transplants, growers depend on reliable inputs, especially growing media and nitrogen fertilizers, to maintain crop performance. However, in recent years, both of these foundational inputs have come under increasing scrutiny due to environmental concerns, rising costs, and supply chain vulnerability. Nitrogen remains the primary driver of plant productivity across horticultural systems. Adequate nitrogen supports vegetative growth, canopy development, and overall plant quality. Yet the global nitrogen fertilizer system is both energy-intensive and vulnerable to disruption. Most synthetic nitrogen fertilizers are produced through the Haber–Bosch process, which converts atmospheric nitrogen…

Growing Knowledge: YPC Members Share Their UF Greenhouse Training Experience

What happens when young professionals in floriculture get the chance to deepen their technical knowledge and immediately apply it in their work? For three members of our Young Professionals Council (YPC), that opportunity came through the University of Florida’s Greenhouse Training Online courses. Through AFE’s educational grant program, we sponsor these 4-week, award-winning certificate courses from UF/IFAS Extension. As a special opportunity provided to the YPC, Maleah Wellmann of Bell Nursery, Mike Wijesinghe of Bell Nursery, and Danielle DelConte of Ball FloraPlant each completed a course designed to strengthen greenhouse production knowledge. From plant disease diagnostics to irrigation management and climate control, the lessons they learned are already helping them think differently about challenges in the greenhouse and bring new…

Advancing Powdery Mildew Resistance in Gerbera Through CRISPR Gene Editing

Powdery mildew is one of the most persistent and economically damaging diseases affecting gerbera production. While some cultivars show partial resistance, most commercial varieties rely heavily on fungicide applications to maintain quality and marketability. Traditional breeding for resistance is time-intensive and difficult to apply to established cultivars, and transgenic approaches can face significant regulatory hurdles. A recent project, led by Dr. Dayton Wilde and his team at the University of Georgia and supported by AFE, explored a promising alternative: using CRISPR gene editing to develop powdery mildew-resistant gerbera more efficiently. Building a Gene Editing Platform for Gerbera Before targeting disease resistance, researchers first needed to establish reliable tissue culture and transformation systems for gerbera. Optimized protocols were successfully developed for…

Global Collaboration in Bloom at Proflora 2025

Staff and representatives from AFE and Ceniflores stopped for a photo among some of the entries from the Outstanding Varieties Competition. This month, I had the privilege of representing AFE at Proflora 2025 in Bogotá, Colombia—a leading international floral trade show hosted by Asocolflores. Alongside AFE Past Chairman Ken Young, and AFE-funded researchers Dr. Rose Buitenhuis (Vineland Research and Innovation Centre) and Dr. John Dole (NC State University), we joined thousands of growers, breeders, suppliers, and floral professionals from across the globe. I arrived ahead of the show to serve as a judge for the Outstanding Varieties Competition, an honor that connected me with industry leaders from Colombia, the United States, and the Netherlands. We were tasked with evaluating more…

Sustainable Disease Management for Specialty Cut Flowers: Results from New Research

The specialty cut flower industry continues to grow rapidly across the U.S., with demand for locally grown flowers climbing each year. However, growers still face persistent production challenges, and one of the most critical is disease management. Soilborne diseases in particular can devastate crops, leading to 50–75% losses when flowers are grown in field soil. Traditionally, chemical fumigants like methyl bromide were used to suppress these pathogens, but those options are now phased out or heavily restricted due to environmental and health concerns. This shift has left growers searching for sustainable alternatives that protect their crops while meeting consumer expectations for eco-friendly practices. Recent research conducted by Dr. Francesca Hand and her team at The Ohio State University, supported by…

Celebrating One Year of “From the Field”

Hello friends, From the Field is celebrating its one-year anniversary this month! I’ve enjoyed the opportunity to write this column over the past year, and I’ve been fortunate to connect with so many of you since then, which has truly shaped the direction of this newsletter. Speaking with you and hearing your stories continues to be one of the most rewarding parts of my work.  As we begin another year of From the Field, I’d like to encourage you to keep reaching out and sharing what’s on your mind. Your input helps us understand where resources are needed most, and it ensures that every AFE research dollar is directed toward solving the real-world issues you’re facing. We invite you to…

Reducing Peat Use in Container Production, Layer by Layer

The floriculture industry is constantly looking for ways to improve sustainability, and one hot topic is reducing the use of peat moss. Thanks to recent American Floral Endowment funded research from Dr. Jeb Fields and his team at the University of Florida, growers will soon have an easier, more affordable way to reduce peat use without compromising plant quality: substrate stratification, particularly with the use of wood fiber. What Is Substrate Stratification? With stratification, you can think of the pot as a layer cake. Stratification means using different potting media in layers, typically with different media on the top and on the bottom. In this research, the top layer remains peat-based, retaining its excellent growing properties, but the bottom layer…

A New Era for Giving: Why Industry Support Matters More Than Ever

New Tax Rules & Industry Needs Make Giving More Important Than Ever As the floral industry continues to face rising research costs, persistent labor shortages, and increasing competition for young talent, one thing is clear: we can no longer rely on uncertain federal funding or outdated support systems to fuel growth and innovation. Now more than ever, the industry must take responsibility for investing in its future, and that begins with supporting nonprofit charitable organizations like the American Floral Endowment (AFE). For over 60 years, AFE has been the floral industry’s trusted source for funding groundbreaking research, offering scholarships and internships to develop the next generation, and supporting industry-wide education. These programs don’t just happen – they depend on contributions…

From the Field: Let’s Catch Up!

Happy Summer, everyone!  Are you starting to feel it in the air...? That familiar feeling of excitement and anticipation?  Yep, that buzzing feeling can only mean one thing: summer trade shows and conferences! Summer is my favorite season, and these shows are a big reason why. Whether it’s Cultivate (join us there!), AIFD, Ball Customer Days, Far West, ASHS, or the SAF Annual Convention, these events always feel a bit like a school reunion to me: seeing familiar faces, catching up on everything that's happened since last year's show, and enjoying a shared energy that reminds us why we love this industry. A recent tour that AFE Executive Director, Debi Chedester, and I went on at Smithers Oasis, in Kent,…

Managing Thrips Parvispinus: New Research on Cultural and Biological Control

Over the past few years, Thrips parvispinus has emerged as a serious threat to ornamental greenhouse crops across North America. First reported in Florida in 2020 on Hoya and Anthurium, this invasive thrips has now been detected in greenhouse ornamentals, peppers, and landscape plants in the southeastern U.S., and more recently in Ontario. While it can’t survive winters outdoors in Canada and parts of the northern U.S., its wide host range—including Mandevilla, Dipladenia, Schefflera, Ficus, and peppers—means it has the potential to cause significant damage wherever susceptible crops are grown. Thrips parvispinus male (left) and female (right) Growers have reported stunted growth, leaf streaking, and floral damage that reduce crop quality and marketability. Complicating matters, T. parvispinus is suspected of…
