Time for Greenhouse Weed Control

David Owens, Extension Entomologist, owensd@udel.edu

Now is the time to wipe out all weeds growing in and immediately around greenhouses. Weeds in the greenhouse and winter annuals such as chickweed, henbit, dead nettle, and speedwell serve as spider mite hosts and provide shelter for spider mites to overwinter. Going into winter with a clean greenhouses and foundation edge will reduce the possibility of having early season mite activity on transplants. A couple of ounces of caution in the form of herbicide can prevent pounds of active ingredient ‘cure’ in the form of miticides to fields that have been planted with infested transplants.
