hey guys, Got a question: Our temperature here was about 55 today. Tommorrow and Friday it is supposed to be about 65. I have read somewher else that when the soil temperature is about 55 degrees is a good time to put down your crabgrass preventer(?) Now after friday we are supposed to get a huge drop in temps and even go below freezing for a couple of nights. OK, here is the question: should I put down crabgrass preventer on friday ahead of this cold snap, or should I wait till after the cold spell and do it when it warms up again. I guess I just don't know if the crabgrass has germinated yet and if so, does it hurt to put the preventer down and then get real cold temps. I don't want the stuff to germinate, because I know then it is too late for the preventer to do any good. Any help would be greatly appreciated. Thanks!
