The soil prior to installing zoysia sod should be leveled out, with any large debris or rocks removed. The top few inches should be relatively loose and fine to accommodate quick establishment of the sod's roots. The area should be well moistened prior to installation.
Zoysia sod should be laid out just as you would lay bricks, so that the ends of adjacent pieces are staggered and do not meet. They should be fitted firmly together and lightly tamped into place after laying them. If installing on a slope, the pieces should be staked into place to avoid movement.
After installation of the zoysia sod, 1/4 of an inch of water should be applied daily until the roots are established. Afterward, 1/2 to 1 inch of water per week should suffice. Zoysia lawns do better when mowed with mowers that have a vertical or rotary cutting action, such as a reel mower. They should be maintained at a height of between 1 1/2 inches to 2 1/2 inches. Annual applications of fertilizer of 2 to 3 pounds of nitrogen per 1,000 square feet of lawn area are recommended.
