ZOYSIA LAWN WILL START TO GREEN UP. In many areas zoysiagrass lawns are still dormant (bronze yellow color). However, with the arrival of warmer weather, zoysiagrass lawns will begin to green up. Mowing should start after the lawn turns green but prior to the turf growing above 1½ to 2 inches. The normal mowing height is ¾ to 1 inch with a reel mower, and usually set as low as possible with a rotary mower without causing scalping.
Zoysiagrass does not need a lot of nitrogen, usually in the 3 to 5 pounds per 1000 square feet per year. A spring application of nitrogen is usually applied 3 to 4 weeks after the zoysia greens up. The normal rate is ½ pound of nitrogen per 1000 square feet. If annual weeds like crabgrass, goosegrass, and foxtail are a concern a preemergent herbicide should be made during the spring prior to germination. Germination will usually take place once soil temperatures are consistently above 50 to 55 F.
