Can I use the crabgrass preventer in the onion bed/tomato patch to prevent weeds
Unfortunately pre-emergents and selective herbicides are not labeled to be used around edible gardens. They stay in the soil too long. Your only option is a round up type product, like our Round UP Quik Pro, and you can spot treat the weeds. Since Round UP does not stay in the soil very long, it can be used in these areas.
