Zoysia

Homeowner Maintenance Guide

Spring

  • If you have a mature, established zoysiagrass lawn, drop your mower a notch and give your lawn a “buzz-cut” in the early spring. Bag up all the material.
  • After your initial “buzz-cut,” begin mowing your zoysiagrass at the desired height. Keep fine bladed zoysias mowed between .5 and 2 inches. Keep course bladed zoysiagrass mowed between one and two inches.
  • Apply pre-emergent herbicide. This will cut down on summer weeds.
  • Don’t overwater. Zoysia needs about one inch of water a week considering rainfall.
  • Apply fungicide if needed. If you have had a fungus or disease in your zoysia in the past or have quite a bit of shade in the yard, apply a systemic fungicide to prevent future outbreaks.
Fertilize your lawn:

Summer

  • When mowing never remove more than 1/3 of the leaf blade. If you remove more than that, you will stress the grass and it may go brown for a short time. If you are returning from vacation, you may have to mow multiple times to get the grass back to the desired height. Wait about three to five days between each mowing.
  • Do not over water the grass. Zoysia only needs about one inch of water weekly. Water for longer periods of time, less frequently, and in the early morning hours. Take rainfall into consideration.
Fertilize your lawn:

Fall

  • Apply fungicide. This will help the grass enter colder months in healthier condition. If you have had a fungus before, you may need multiple applications in affected areas.
  • Treat with broad-spectrum insecticide if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption. Make sure it offers control for billbugs.
  • During the fall, mowing will occur less often—keeping your zoysia slightly higher will encourage deeper root growth for winter.
  • Water less as temperatures drop—too much water will lead to disease.
  • If you haven’t had past problems with winter weeds, you can forgo herbicide in the fall. If you do get winter weeds, apply a pre-emergent herbicide for prevention.
