Zoysia Dilemma

There are bare spots all over our zoysia grass lawn. How can I repair the damage? —Texelda Lockard, Greenbrier, Arkansas

Dead spots can be the result of insect or disease problems. Knowing the culprit is necessary to select the best treatment.

Sprays work only if the right product is used at the right time. Avoid problems and reduce the need for chemicals with proper care. Avoid excessive fertilization that can lead to disease. Fertilize the lawn when it is about 50 percent green. If desired, you can fertilize 7 weeks later.

Use a low-nitrogen, slow-release fertilizer to reduce the risk of burn and disease that often attacks lush, succulent growth. Keep your lawn at least 1-1/2 inches high, and remove no more than one-third of its total height with each mowing. Taller grass forms deeper roots and is more pest and drought-resistant.

With proper care, the healthy grass may fill in the dead areas. Otherwise, try seeding or planting sprigs in these bare spots. Consult your local extension service or lawn care professional for proper diagnosis if the problem persists.
