Hi-Yield Crabgrass Weed Control is a pre emegent herbcide that should be applied prior to weed germination for best results. This product will have no control on actively growing weeds. For pre emergent control of summer weeds, pre emergents should be applied in early spring when soil temps are around 55 degrees however timing can vary from region to region. For specific timing recommendations, contact your local cooperative extension office to enquire when the appropriate application time would be in your area. We also have our Cool Season Lawn Care Schedule and Spring Pre Emergent Guide for more information.
