Unleashing the Power of Ethephon: A Game-Changer for Container Plant Growth
Taming the Wild Growth of Perennials
Imagine a world where you can control the height of your beloved perennials without harming their overall health. Well, a groundbreaking study has revealed the secret weapon: ethephon substrate drenches. This innovative approach allows growers to regulate stem elongation, resulting in uniform and healthy plants ready for the retail market.
Managing the Growth of Annual Bedding Plants
But here's where it gets controversial... What about annual bedding plants? Another study delved into the effects of ethephon drenches on these plants. The findings? Controlled applications can limit excessive growth, creating more compact and visually appealing plants. This is a game-changer for growers seeking efficient and cost-effective growth management strategies.
The Impact on the Industry
Effective height and growth control are not just about aesthetics; they are crucial for operational efficiency in ornamental horticulture. This research provides growers with the tools to enhance plant uniformity, reduce labor-intensive pruning, and boost crop marketability. It's a win-win situation, promoting sustainable and profitable practices.
Behind the Scenes
Led by W. Tyler Rich, a research associate, this study was part of his Master of Science journey at The Ohio State University's Department of Horticulture and Crop Science. The work focused on expanding the label for Collate® 2L (ethephon), which, as of May 2025, is the only ethephon product approved by the EPA for substrate drench use and foliar sprays. These findings are a game-changer for growers, offering guidance on adoption, application timing, and responsible use in floriculture production.
