Time to Think About Controlling Yard Weeds

If you are thinking about putting down a preemergence herbicide, to keep the weeds out of your lawn, you want to wait until the soil temperature is 50 degrees or warmer, according to Meteorologist and gardener Tony Schumacher. Then, he says, you want to lay down the application seven to 10 days before the weeds start to sprout, and you want to wait until after any rain in the forecast.
Schumacher says we could get an inch of rain or so this weekend, so you will want to wait until after that.
