Zoysia grass is sometimes called a "super grass" because of its durability; however,
the popular perennial grass is also slow-growing and invasive. That may be good for your yard, but not your neighbor's. Its invasive characteristic is also bad news for weeds but good news for homeowners in terms of maintenance. Zoysia is commonly grown in the South and southern regions of California.
Mow zoysia grasses to a height of 1 to 2 inches. Be sure to keep your mower's blade especially sharp when cutting zoysia, which develops stiff grass blades. For a newly seeded lawn, don't mow until the grass reaches a height of 2 ½ to 3 inches.
It's best to fertilize zoysia during the summer. While it may be tempting to apply a subsequent fertilizer in a few weeks or months, don't. Zoysia grass requires much less fertilizer than most other common grasses, and over-fertilizing will cause problems with the lawn's health and development.
Varieties of zoysia grasses are subject to several common diseases; among them are leaf spot, brown patch, dollar spot and rust. Before any treatment is applied, be sure the disease is correctly identified to proceed with the best course of treatment. Local county extension services and garden centers are great sources to help diagnose these diseases and to recommend a proper course of action.
When grown in the South, zoysia grass tends to be plagued with crickets, moles and nematodes. Billbugs and grubs present a threat to zoysia grown in areas outside the South. Adding organic matter to soil helps to control nematodes. Billbugs should treated in the early spring, as soon as activity is noted. A number of commercial options are available to treat the pests.
Newly seeded zoysia lawns require frequent watering to help them get established. Watering frequency and amount should be reduced once the lawn has grown in. For best results, water during the early morning.
