Zoysia is a low-growing grass that should be kept mowed at about 1 to 3 inches depending on the type of yard space and the sun exposure. Those with a lot of sun exposure will want to trim their grass to a maximum of 1.5 inches, while those with partial shade will want to consider a 2- to 3-inch mowing height. This is also convenient for those who don’t want to do a lot of maintenance since zoysia grass tends to grow slowly.
