Does it matter when you put out pre emergents. Can i put them out now or do i need to wait until april or may?
Also what is the best pre and post emergent for the money.
Thanks:blob3:

It goes done before the subject weeds emerge. I treat fall for winter weeds, early spring for spring weeds. I use post emergent /spot spraying after that.

Soil temps in Mid-Tenn. are rising fast. Put out pre-emergent asap. Soil temps are the critical factor. If it reaches about 52 degrees for a week or so crab will germinate.
