Huge Poa Annua problem
I live in Massachusetts, zone 7. My lawn is getting invaded with Poa Annua. I've done some research and it seems the only way to fight this thing is using a preemergent like Scott's TB with Halts.
Guys, when do I put it down? Ive read in the late summer when the temps drop below 70F, but the temps right now are below 70F already ???????
Please help! Thanks.
