Zoysia Grass Care & Maintenance


Zoysia grass is a hardy, quick-growing grass. Zoysia is extremely cold and heat tolerant; it flourishes in the brutal heat of the south and is able to survive weather as cold as 30 degrees below zero. The grass grows thick, and is prized for its ability to choke out existing weeds and prevent new weeds from establishing themselves. Zoysia will provide years of full, green growth if it is cared for properly.


Keep both zoysia seed and newly-laid sod moist for two weeks. Established zoysia tolerates droughts, but the seed and newly-laid sod is fragile. If allowed to dry out, zoysia seeds and new sod turns yellow and dies. To keep the soil moist, water thoroughly every morning before 10 a.m. Keeping the soil moist for two weeks enables the root system to establish itself.


Cut zoysia when the blades of grass are approximately 3 inches tall. If zoysia is allowed to grow taller, it will bend over onto itself. Set the lawn mower to a height of 1 1/2 inches tall for yards that are in full sun, and 2 - 2 1/2 inches for yards that are in the shade.


Zoysia grass tolerates dry conditions. The grass will grow and flourish with rainfall. No additional watering is needed unless several weeks pass between rains. In the deep South, additional water is needed if the blades of grass appear curled or yellowed.


Zoysia grows well without the use of fertilizers. If you feel the need to fertilize your zoysia, use a 16-4-8 fertilizer during spring and summer, and a 5-10-15 fertilizer during the fall. Zoysia goes dormant in winter; fertilizer applied during the winter will burn and kill the grass.


White grubs are the primary pest that affects zoysia grass. To keep infestations in check, it's important to monitor the soil during the summer and fall months. If the grub count reaches four to five grubs per square foot of soil, treat the zoysia grass with an insecticide that targets white grub worms.
