Q: My wife and I are having a discussion about our Meyer zoysia. I have always mowed it one inch high. My wife believes that I should mow it at two to three inches high.

A: Mowing at one inch high is a bit low unless you are using a reel mower. I think you can mow your zoysia at two inches high in spring and fall but raise the cut to two and one-half inches in the heat of the summer. Zoysia MUST be cut with a sharp mower blade. Otherwise grass tips are shredded, causing a yellow appearance. Also, make sure you are not waiting too long between mowings. Removing more than a third of the blade at one time will also cause a yellow appearance.
