Zoysiagrass is a warm-season grass variety that is native to areas in Southeast China and Japan. The grass is popular because of its ability to spread quickly when planted in plug form. A plug consists of one-inch square sections of sod that are planted directly into the soil. The benefit of planting plugs is that the roots are established rhizomes that spread faster than applying seed to the lawn.
Mow the existing grass to a height of no more than 1 inch. Collect the cut grass after mowing using a mower with a bagging attachment or a rake.
De-thatch the lawn area to remove matted and dead grass build up at the soil level. Water the lawn enough after the de-thatching to soften the ground.
Dig holes slightly larger than the root system of the plug to plant the Zoysia plugs.
Add a 1/2- to 1-inch layer of organic compost to the bottom of the hole and place the plug into the hole. Gently fill the remaining space around the plug with soil. Pack the soil around the plug to hold it in place.
Continue to plant Zoysia plugs in a checkerboard pattern across the lawn. Space the plugs 12 inches apart.
Water the new plugs on a daily basis with 1 inch of water for the first two weeks or until the roots become established. Place a small open can in the middle of the lawn to measure the watering depth.
Fertilize newly planted plugs with a 1-2-1 grass fertilizer after planting, following the manufacturer's label for dosage. Continue to fertilize the lawn each month during the first growing season to stimulate the growth and spread of the grass.
