Hi there, New to the forum, zone 7, Charlotte, NC. I renovated the lawn last fall, had many pines removed, ground the stumps, tilled the entire lawn and raked as much of the grindings out. I didn't add topsoil but I fertilized and planted Lesco Trigold. It came up beautifully and is still mostly green. We've had lots of sun and rain and it drains well. I've kept the mower on maximum height and spread a weed and feed two months ago, then an insecticide a few weeks ago. There have been some inconsistent patches of growth due to, I thought, high concentrations of stump grindings. I'm now seeing brown circles all over the lawn even in the healthy areas. Do you think I have "brown patch"? How can I correctly diagnose and cure this problem? Thanks, Scot in Charlotte.
