Q: I had my fescue lawn aerated last fall and put fescue seed out at the same time. The fescue is growing great but there are lots of weeds.
A: The aeration probably brought up some dormant weed seed, which is what you’re seeing now. Several species of weeds have seeds that can sleep in the soil for several years. If the weeds have oval or ragged leaves you can use and broadleaf weed killer at ½ strength now and again in three weeks.
