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.
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 with Lawnifi, the recommended liquid fertilizer.
