Zoysia grass care
Zoysia spp. occupies an unusual niche in the warm-season world: it's slower-growing than bermuda grass, more shade-tolerant than most warm-season grasses, and cold-hardy enough to persist in zone 6. That combination makes it attractive for transition zone lawns that don't want to deal with long.
Zoysia spp. occupies an unusual niche in the warm-season world: it's slower-growing than bermuda grass, more shade-tolerant than most warm-season grasses, and cold-hardy enough to persist in zone 6. That combination makes it attractive for transition zone lawns that don't want to deal with long dormancy periods. The trade-off is slow establishment and aggressive thatch buildup.
I don't grow zoysia on Long Island — not worth the 5-month dormancy at zone 7a — but I'd consider it at zone 7b or warmer, particularly in lawns with some tree shade.
Species overview
Three main Zoysia species are used in lawns:
| Species | Texture | Cold hardiness | Best use |
|---|---|---|---|
| Z. japonica (Japanese zoysia) | Coarser | Zones 5—9 | Transition zone, high wear |
| Z. matrella (Manilagrass) | Fine | Zones 8—10 | Warm-season lawns, fine texture |
| Z. tenuifolia (Mascarenegrass) | Very fine | Zone 9—11 | No-mow or ornamental |
Per NC State TurfFiles, most zoysia sold for home lawns is Z. japonica or a hybrid between Z. japonica and Z. matrella. The hybrid varieties — Zeon, Zorro, Emerald — offer finer texture while retaining moderate cold hardiness.
