Weeds are a considerable economic pest for woody ornamental plant growers. Pre-emergent herbicides and hand weeding are typically used to control weed seed germination and minimize impacts from weeds for environmental horticulture container growers. A regional hands-on workshop was developed to assist growers to manage container weeds more efficiently and economically. Class subjects covered weed identification, nursery weed best management practices, and a weed management success story. A hands-on, herbicide calibration education section was held outdoors to teach proper granular herbicide application. Growers viewed demonstration plots that were created to screen 19 pre-emergent herbicides and organic mulch combinations for efficacy against fall/winter weeds commonly seen in woody plant production. Growers were able to assess herbicides and weeds combinations that would work for their situations. Class time was allowed for a shared discussion of plot observations. Participants reported 87% change in herbicide/weed knowledge, and 100% reported that their practices would change from the workshop. 96% believed that the workshop would save them money and estimated savings of $3,700 per year.
