UMaine Extension offers webinar on managing weeds in greenhouse ornamentals
University of Maine Cooperative Extension will host a webinar focused on identifying and managing weeds in greenhouse ornamental production, Monday, Feb. 2, 2026, from 6 to 7:15 p.m.
“Effective Weed Management in Greenhouse Ornamentals” will be led by Manjot Sidhu, assistant Extension professor of horticulture and ornamental horticulture specialist at UMaine.
Weeds compete with ornamental crops for space, light and nutrients, ultimately reducing plant quality and overall productivity, according to the Extension, in a news release. In this webinar, participants will learn practical strategies for addressing these challenges, including how to recognize common greenhouse weeds, understand their biology, and apply a range of control methods. Topics will cover cultural and mechanical practices, as well as key considerations for effective chemical control.
This session will offer growers actionable guidance to support healthier crops, more efficient production and long-term weed management success in greenhouse systems. Eligible for 1 Maine pesticide recertification credit.
The webinar is part of UMaine Extension’s Commercial Horticulture Webinar Series, held on the first Monday of each month.
Registration is required; sliding scale fee options are available. Register on the event webpage to attend live or receive the recording link. For more information or to request a reasonable accommodation, contact Rebecca Gray at 207.356.1348 or extension.gardening@maine.edu.
