Corn speedwell is a pervasive problem in lawns in central NJ. Would an early fall application of a lawn fertilizer with pre-emergent herbicide be a recommended way to control this winter weed? It is listed on a Vigoro fertilizer with preemergent crabgrass control if applied in the fall. Does anyone have experience with this approach? Thanks.
