How to Maintain Zoysia Grass
- 1). Water newly planted Zoysia grass every other day until the roots are established. Allow established grass about 1 ½ to 2 inches of water every week, as recommended by Pike Nurseries. During droughts, observe the color of the grass; if it begins to appear discolored and straw-like, it needs more water.
- 2). Apply a nitrogen fertilizer to the grass in the early spring when it is starting to turn green. According to the Texas Cooperative Extension, allow for 1 lb. of nitrogen for every 1,000 square feet of lawn. Pike Nurseries recommends allowing the grass a second application of fertilizer about two months later.
- 3). Apply a winterization feeding to the Zoysia grass in the fall, just before it enters dormancy, usually in October. Winterizers help the root system continue to grow into the fall. It also provides key nutrients such as potassium and phosphorus. This helps your grass resist diseases and survive weather extremes, such as droughts.
- 4). Mow Zoysia grass during the growing season when it is about 1 to 2 inches tall. Zoysia grass tends to grow more slowly than other varieties, so expect to mow only about once per week.
- 5). Prevent weeds by applying a crabgrass preventer in October and again in February, according to Pike Nurseries. If your lawn does show signs of weeds, use a lawn weed killer that specifies it is safe for Zoysia grass. Apply the product in the cooler part of the summer, when temperatures are less than 85 degrees F.
