Hi all, I had a company put down a pre-emergent on all of my lawn and I was wondering how long to wait before I walk on it? I know that sounds silly but it's the first time I've had a professional company put it down and I didn't talk to the guy who did it (he was gone before I realized it). I didn't catch the name of the company as they contract with my local garden center. I wanted to do my work in my woodland area in the back of my property but the only way to get to it it walk across the grass. The pre emergent was put down yesterday (Monday, 3/16). Thanks! Gayle
