OK, I sprayed a yard 2 1/2 weeks ago with MSMA to take care of this guys crabgrass (about 35-40% of his yard). About 6500 sq. ft. total is his property. Before I did it, I put down 29-3-4 fertilizer with iron. This was on Tuesday an it was supposed to rain on Thursday for 2 days. It didn't and hasn't rained for 3 weeks now. He has a lot of turf burn. I sprayed as directed on the label. My question to you guys is, is there anything I can do to reverse this? I have my license and this is my first year spraying. I did tell him to wait till spring and he wanted it done. Any advice is very much appreciated.
