Unfortunately, the variable weather makes identification of problems more difficult unless you know exactly when they first made their appearance. Here are a few highlights from the past week. Most samples are from poorly drained, compacted areas.
Most samples are also of the much more problematic basal or crown rot stage.
The long term solution is to really fix the turf growing conditions- better aeration and drainage. When you can see massive root growth in the aeration holes, you get an idea of how restricted plants away from those holes are. It makes numerous chocolate brown spots that can progress into melting-out and crown rot. Cool, wet conditions and high nitrogen fertility favor the disease. We'll be watching for that later.
