Zoysiagrass is a common grass species used in backyards across North America. The grass species is prized for its fast growth, very low-water needs and density that deters weeds and can withstand relatively heavy foot traffic. Though zoysiagrass can be maintained used standard lawn care practices, some issues---the plant's low water needs, for example---require attention that's specific to the zoysiagrass species.
Increase the sunlight on your zoysiagrass by trimming back trees and overhanging shrubs. Though the species can grow in the shade, it responds well to a minimum of 6 hours of direct sunlight and will grow thicker than its shadier counterparts.
Fertilize your zoysiagrass. Though it's not as nutrient hungry as other grass species, fertilizing can boost the lawn's health and ward off various diseases and maladies caused by nutritional deficiencies. Use a standard lawn fertilizer, applied according to the label's guidelines because potency varies by product, every 4 to 6 weeks from the months of May through August when zoysiagrass grows most vigorously.
Water your zoysiagrass. This is a drought-tolerant species that requires water only on an as-needed basis. Water only when there is no natural rainfall, and even then only once every two to three weeks. When you water, apply water until the soil is wet to a depth of 5 inches. This encourages deep root growth as opposed to shallow watering.
Mow the zoysiagrass. Mowing is about more than just maintaining your lawn's appearance, but also helps keep the zoysiagrass healthy. Cut to a height of 1 to 2 inches during the spring and summer, then raised by an inch in the fall to help prepare the zoysiagrass for winter.
