Fescue – Spray Before Mowing?

Q: Is it best to spray weed control on a fescue lawn before or after the lawn is cut?

A: Great question! You’ll get best results spraying weed killer a couple of days after the lawn has been mowed, when the weeds are actively growing and recovering from damage. Spray, then wait a few days before mowing again, to give the chemical time to be thoroughly absorbed by weed leaves.
