I am in the process of cutting my lawn down from 4 to 2. The grass is Jamur Zoysia. I am in zone 9a. At 4 the lawn is a very lush green color, as I reduce the height, 0.5 at a time the grass leaves/stems are pale brown, if I allow the grass to grow taller, (i.e. skip a cutting) the grass tips green up, I do not believe it is thatch as I can see the grass down to the soil. How do I transition to the lower setting, and get the grass blades adjusted to the lower settings to produce the green blades? The lawn receives about 1 of water/week unless mother nature kicks in.
