QuestionI installed Bermuda sod four years ago, after second year I started having dead spots, 12 inch dia. +. The first two years I used the Scotts Program four times a year,since then I have used weed & feed, plus Scotts & Bayer Crab grass, weed killers. Last year I overseeded with perennial. rye. I live in South west Missouri.
Answer If you are seeking a remedy for the dead spots, we first have to isolate the cause. Eliminate (or not) irrigation. Run the system to ensure that it is covering all areas adequately and completely. Next, eliminate insects by soap-flushing the problem areas. If both water and insects are eliminated, then it is likely a fungus, probably brown patch. Confirm this with your County Extension agent who can also advise on control.
