Q: I cannot find pre-emergence for centipedegrass at the local garden stores. What ingredient do I search for to use on my lawn?
A: I think most, if not all, pre-emergent herbicides are labeled for use on centipedegrass. The window of opportunity to prevent winter weeds is almost closed for this season but you can attempt partial control by using a pre-emergent now. If you have emerged broadleaf weeds like chickweed or henbit, either pull them or use a herbicide. You may be aware of the problems that occur from overusing weed killers on centipedegrass. Choose a herbicide specifically labeled for use on centipedegrass or St. Augustine grass and use it sparingly.
