Everything grows in the rain and with the amount of rain we got last year, it came back as weeds; or clovers in my yard. Weed Man was very responsive to my needs! When I noticed these weeds popping up in between applications and after rain storms, Weed Man came right back out and re-treated absolutely free. What else can you ask for? It's an amazing company who really cares about their customers. Thumbs up to Weed Man!
