It does not tolerate traffic, compaction, high-phosphorus soils, low-potassium soils, high pH, excessive thatch, drought, or heavy shade. Proper watering helps prevent or reduce problems later in the summer. Thatch Removal Power rake (vertical mow) to remove thatch ( the layer of undecomposed grass) in late May if it is thicker than ½ inch. Yellow appearance may indicate an iron deficiency. It is better to apply an insecticide as a preventative as opposed to having to resolve an infestation once damage has already occurred—it’s probably less expensive too.
