Seasonal Maintenance Guides for Your Zoysia

null

MOWING

When mowing during the summer, never remove more than 1/3 of the leaf blade at a time. If you remove more than that, you will stress the grass and it may go brown for a short time. Taller blades provide more shade for your root system to stay cool and retain moisture during the hot summer days. 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.

null

WATERING

Do not over water the grass. Zoysiagrass 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.

null

FERTILIZATION

For optimal results, feed your lawn monthly during the summer season by applying the Lawnifi Summer Box liquid fertilizer program.

null

WEED CONTROL

Apply post-emergent herbicides as needed to control summer annual and perennial broadleaf weeds. Crabgrass species, goosegrass, dallisgrass, purple and yellow nutsedge, annual sedge and sandbur can be controlled with post-emergent herbicides. If crabgrass and goosegrass are present, make a note to apply a pre-emergent herbicide next spring. Do not apply herbicides during a drought, when grass and weeds are not actively growing or when temperatures exceed 90 degrees. Consider spot treating weeds to avoid burning the grass during hot summer months.

null

INSECT CONTROL

Check for and control any white grubs. Treat with an insecticide if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption. August is the best time to control grubs because they are small and feeding near the soil surface.

null

FUNGUS CONTROL

Treat with a fungicide if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption.

MOWING

During the fall, mowing will occur less often—keeping your zoysia slightly higher will encourage deeper root growth for winter.
null

WATERING

Water less as temperatures drop—too much water will lead to disease.

FERTILIZATION

For optimal results, feed your lawn monthly during the fall season by applying the Lawnifi Fall Box liquid fertilizer program.
null

WEED CONTROL

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.
null

FUNGUS/INSECT

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.

MOWING

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 coarse bladed zoysiagrass mowed between one and two inches.

null

WATERING

Don’t overwater. Zoysia needs about one inch of water a week considering rainfall.

For optimal results, feed your lawn monthly during the spring season by applying the Lawnifi Spring Box liquid fertilizer program.

WEED CONTROL

Apply pre-emergent herbicide. This will cut down on summer weeds.

FUNGUS/INSECT

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.

  • A thick, luch lawn is the best deterrent to weeds.

null

DISEASE CONTROL

  • Overly wet grass + shade = fungus problems.

  • Use multiple fungicide applications to treat affected areas.

null

INSECT CONTROL

  • Use a broad spectrum insecticide that controls chinch bugs.
  • For a once-a-year treatment, July & August are good months.
  • If using a granular insecticide, water in after application.
  • Look for insect damage on grass blades and/or roots.

A WORD OF CAUTION FOR NEWLY SODDED LAWNS

A pre-emergent contains a chemical that prevents a weed from putting down roots. Because it is a root inhibitor, it can also negatively affect your new lawn, which is trying to establish itself by putting down roots.

If you successfully killed and removed your old lawn, including all the weeds in it, your newly sodded lawn should have relatively few weeds. It is suggested that you hand pick weeds out of your newly sodded lawn for the first season.
