Tips for Fertilizing Empire Zoysia

Fertilizing

• Empire Turf recommends fertilizing Empire Zoysia three times per year, in spring, summer and fall. In spring and summer, use a 16-4-8 time-release fertilizer. In fall and/or winter, use a balanced 10-10-10 time-release formula. In any season, using a product that contains iron will improve the deep green color of your Empire Zoysia.

Fertilization and Turf Health

• Keep your grass growing at a slow, steady rate by using reduced-nitrogen fertilizers and iron-rich products in the spring and summer. Overly fast leaf growth instigated by improper fertilization stresses grass's resources, making it more susceptible to weeds and pests.

Mowing and Fertilization

• Mowing is particularly important to zoysia grasses, and mowing practices should always be considered in discussions of zoysia turf fertilization. Cutting too much of the blade at once can damage zoysia. A deeply cut blade of grass will struggle to provide itself with nutrients and the outward signs -- browning, wilting -- will lead owners to the conclusion that the turf needs fertilizing. Fertilization can lead to quick, leggy growth and a further expenditure of reserves, leaving the turf open to infestation by pests or disease.

Recommended Mowing Heights

• Empire Turf recommends keeping zoysia grass at a height of 1 to 2 inches. One inch is optimal; heights above 3 inches will reduce the quality of your Empire Zoysia. If using a reel mower, Empire Zoysia can be mowed to heights as low as 1/2 inch. Only cut 1/3 of the grass blades or less at a single mowing because cutting any more deeply can lead to damage and a vicious cycle between fertilization, fast unhealthy growth and mowing that only leads to further damage.
