Zoysiagrass is a warm-season grass that spreads by rhizomes and stolons to produce a very dense, wear-resistant turf. It is best adapted to the Piedmont and Coastal Plain regions of North Carolina, but some of the more cold tolerant cultivars can be grown in the western part of the state as well. There are three major species of zoysiagrass suitable for turf including Japanese lawngrass (Z. japonica), mascarenegrass (Z. tenuifolia), and manilagrass (Z. matrella). Zoysiagrass can often be confused with bermudagrass. However, zoysiagrass has hairs standing upright on the leaf blade whereas bermudagrass does not. Zoysiagrass is also stiff to the touch and offers more resistance than bermudagrass.
lawn Maintenance for June - August
Apply ½ pound of nitrogen per thousand square feet in late June or early July and repeat in mid-August using March-May fertilizer guidelines.
Follow the March-May insect control guidelines. August is the best time to control grubs because they are small and close to the soil surface.
Follow the March-May irrigation guidelines.
Follow the March-May mowing guidelines.
Vertically mow in June using the March-May thatch removal guidelines.
Apply postemergence herbicides as needed to control summer annual and perennial broadleaf weeds such as knotweed, spurge, and lespedeza. Do not apply postemergence herbicides unless weeds are present, grass is actively growing, and the lawn is not suffering from drought stress. Crabgrass, goosegrass, dallisgrass, nutsedge, annual sedges, and sandbur can be controlled with postemergence grass control herbicides. Two or three applications 7 to 10 days apart are required for effective control. Zoysiagrasses are sensitive to these compounds so select the application carefully.
