Yes I know, I am just a pion scrub with only 3 clients, but I would still love some help. Of the three, one of them is convinced I have burned her lawn. Here's the story: In mid-March I put down customer supplied fert&crabgrass preventer per her request. Exactly a month later I put down Lesco 5-10-20 Pre-M which is what the guys at Lesco recommended to get full coverage on the crabgrass. Well now about 80% of the grass is crispy, crunchy and brown. I know we are in quite a drought in the Carolinas but her grass is really bad. Question is: Is it possible that I did burn her grass? Lesco rep. says it is impossble with the 5-10-20 even if I put down 6 times the recommended amount. Was a month too soon to put down a second application? She "claims" she is watering like crazy which I do believe, maybe it's just not enough. I know this was long winded, but any help would be great.
