Hi! I have a problem, I think my contractor has applied too much pre-emergent to my lawn and I am afraid it is going to burn it all! It was 100 lbs of TurfGro professional 0-0-7 over about 13000 of lawn. It is Bermuda grass, well established, and currently dormant. The bag said no more than 6,6lb/1000 sq feet per application and the recommended rate for our region is 5/1000 sq feet. By my calculations, the applied rate was about 8.3 lb/1000 sq feet.
I guess my question is - how bad is it? Is it gonna damage existing grass?
Do I need to do anything about it or it is not that bad really?
It just happened yesterday, should I be watering it like crazy to leech some of it out? Is it bad enough that I should buy some activated charcoal (I would rather avoid that, cause that can get expensive).
My primary concern is that my beautiful lawn dies. Please help me!
