Pre-emergent crabgrass killer
Does anyone know of a good pre-emergent crabgrass killer that is not mixed
with a fertilizer? Seems only the mixtures are in the stores. I want to be
able to apply the pre-emergent when the forsythia bloom and then later
around the end of May apply fertilizer. Unfortunately, these aren't at the
same times. I read that corn gluten is a good pre-emergent for crabgrass but
can't seem to find that anywhere. Any advice is welcome.
