I have been contacted by 4 people so far whom use Scott's Turf Builder products themselves, Lawn Doctor Treatments, and TruGreen - everyone of there yards has giant brown spots and just looks terrible. They all tell me normally the lawn looks great but this year everything went down hill. I will get some photo's of them and post, but I wanted to ask; has anyone else come across this and what are you doing to fix? My first step was to get a soil test from each of the properties. I told them to mow it at 3 1/2" (blue grass) and dropping down to 2 1/4" approximately in the later fall. Thinking about a dethatch this fall for them but not sure with the dramatic changes in weather (82 two days ago, 62 high today). My guess is they over did it with chemicals and the test will show one or more of the levels are off, but I was wondering if anyone else had feed back / similar situation.
