Zoysia
Zoysia is a warm-season grass celebrated for its exceptionally dense, cushiony texture and outstanding wear tolerance. Once established, it crowds out weeds naturally and is among the most durable lawn grasses available. The tradeoff is slow establishment and a long dormant period.
Tolerance & Maintenance
How to Identify Zoysia
- ✓Stiff, wiry blades that feel somewhat coarse underfoot
- ✓Medium blade width (2–5 mm) depending on variety; zoysiagrass japonica is coarser, matrella is finer
- ✓Spreads by both rhizomes and stolons, forming an extremely dense mat
- ✓Medium green to dark green color; lighter green than Bermuda
- ✓Holds a neat, manicured appearance at low mowing heights
Mowing
Zoysia's dense growth means it doesn't need frequent mowing, but its tough blades wear out mower blades quickly. Keep blades sharp. Avoid letting it get too tall before cutting.
Watering
One of the most drought-tolerant warm-season grasses. Goes dormant during dry spells but recovers well. Overwatering promotes thatch and disease.
Fertilization
Zoysia requires less fertilizer than Bermuda. Over-fertilizing promotes thatch and disease. Use a slow-release nitrogen source.
Common Problems
Slow Establishment
Takes 2–3 seasons to fully fill in from plugs or sod. Germination from seed is extremely slow. Weeds can be a problem while the lawn establishes.
Thatch Buildup
Dense growth creates thatch rapidly. Dethatch every 1–2 years in late spring or early summer. Excessive thatch causes poor water penetration and harbors pests.
Long Dormancy
One of the first grasses to go dormant in fall and last to green up in spring. Dormant period can be 4–6 months in Zone 6–7.
Brown Patch
Circular tan patches in summer during humid conditions. More common when over-fertilized or overwatered. Reduce nitrogen and improve drainage.
