Actually, using too much can hurt. The tops die, but the plant recovers.
The trick is to mix the correct ratio and give it time to work. Too fast and you get to do it all over again.
Yes exactly right thats just what I learned from a landscaper and he was right you will think you haven't done anything and a couple weeks later its all dead for good. :thumbsup:
I use generic 41% glyophosate with surfactant rather than roundup but I still call it roundup.
