Zoysiagrass Removal

Overview

Zoysiagrass is a warm-season grass with a deep root system that looks lovely and green when temperatures are above 70 degrees Fahrenheit. As soon as temperatures drop below 50 degrees Fahrenheit, however, zoysiagrass turns brown and remains that way until the weather warms up again. Rather than live with dead-looking landscaping for months, many homeowners decide to rip out the zoysiagrass and replant with another, more cold-tolerant variety. Zoysiagrass needs to be healthy in order to absorb herbicide. If you are planning on planting a new lawn, removal of zoysiagrass should be done five to six weeks prior.

Step 1

Continue to water the lawn as you normally do and mow it to 2 inches, regularly. Do not allow the zoysiagrass to become stressed for water.

Step 2

Fertilize the zoysiagrass with 1 pound of nitrogen for every 1,000 square feet of lawn.

Step 3

Perform the first herbicide spray when the zoysiagrass is green and healthy. Spray the zoysiagrass, mid-morning, with a glyphosate non-selective herbicide, according to label instructions. Allow the herbicide to dry. Do not water after application.

Step 4

Water the zoysiagrass normally the following day. Continue your normal watering pattern for 10 days.

Step 5

Apply one-fourth pound of nitrogen for each 1,000 square feet of zoysiagrass. Wait for new zoysiagrass growth.

Step 6

Spray any remaining or new, green zoysiagrass with the herbicide. Again, allow the product to dry and do not water until the following day, then do not water it again. The zoysiagrass should be killed within one week.

Step 7

Rake up the dead zoysiagrass. If there are any remaining live patches of grass, repeat the procedure from the beginning.

Tips and Warnings

  • Herbicides may contain dangerous chemicals. Read all package instructions and warnings and wear protective clothing during application. Do not apply the herbicide on a windy day as the product can drift to desirable landscape plants. Zoysiagrass has a very deep root system, so you have to quite diligent in following the removal steps.
