I have read your write up for lawn care which has provoked me to post a reply. It is July here in PA and I have unusual dead spots. Thatch, grubs, burnt? Take a look what do you think? I think I will need to aerate and dethatch in the fall/late summer. This is the second summer I've owned this house. Fertilized and lined this past spring, grass came really green and now it looks a little dry.. Thanks
