Q: I was getting ready to reseed my fescue lawn and my lawn care company put out Princep pre-emergent while I was not home. How long do I have to wait before I can reseed?
A: Simazine (Princep, etc) is a common pre-emergent used by professionals. It is very effective at controlling weeds but the label states that you have to wait six months before reseeding. Fortunately, March is the second-best time to plant fescue seed; you’ll have to wait until then.
