Zoysia Emerald
Zoysia japonica × Zoysia matrella
grassZoysia Emerald is a hybrid warm-season turfgrass known for its dense, fine-textured emerald-green color and excellent wear tolerance. It combines the hardiness of Japanese zoysia with the finer texture of Manila grass, creating a premium lawn grass suitable for high-traffic areas. This cultivar is drought-tolerant once established and requires less maintenance than traditional cool-season grasses.

Establishment
2-3 weeksNewly laid sod or plugged areas with visible seams or gaps; roots establishing contact with soil
Keep soil consistently moist but not waterlogged. Light, frequent watering (daily or every other day) for 2-3 weeks. Avoid foot traffic. Mow after 2-3 weeks once grass reaches 1-1.5 inches.
Active Growth
4-8 weeksDense green shoots filling in, runners spreading across soil surface, grass developing deeper root system
Mow at 1-1.5 inches height every 7-10 days during growing season. Reduce watering frequency as roots deepen. Apply light nitrogen fertilizer every 6-8 weeks.
Peak Summer Performance
4-6 months (June-September)Fully established deep emerald-green lawn with dense, fine-textured turf and vigorous horizontal shoot growth
Maintain mowing schedule at 1-1.5 inches. Water deeply 1-2 times weekly during hot, dry periods. Avoid excessive fertilizing. Monitor for heat/drought stress in extreme conditions.
Dormancy Transition
2-3 months (October-November)Gradual color change from emerald-green to tan/brown as temperatures cool in fall and winter; below-ground root and rhizome activity continues
Reduce watering frequency as growth slows. Do final fertilizer application in early fall. Mow as needed until grass stops growing. Remove leaves and debris to prevent disease.
Winter Dormancy
3-4 months (December-March, depending on zone)Brown or tan-colored dormant grass; minimal above-ground activity; underground root system remains alive
No watering needed unless experiencing severe drought. Minimal mowing. Avoid heavy foot traffic and equipment on dormant turf. Do not apply fertilizers.

Common Pests
-
Monitor for wilting in hot weather; use resistant cultivars; apply insecticidal soap or neem oil at early sign of infestation; ensure adequate watering to reduce stress
-
Apply beneficial nematodes in fall; use grub control products in late spring or early fall; maintain lawn health to tolerate minor damage
-
Maintain proper mowing height; apply Bacillus thuringiensis (Bt) or other biological insecticides; chemical controls available if severe
-
Improve drainage and air circulation; avoid overwatering; apply fungicide if severe; maintain proper nitrogen levels
-
Avoid evening watering; ensure good air circulation; reduce thatch; apply fungicide in humid conditions if necessary
Uses
Premium lawn and landscape turf

Water conservation and drought tolerance
HouseholdOnce established, Zoysia Emerald requires significantly less water than cool-season grasses, making it an environmentally responsible choice for water-conscious regions. [source]
Wildlife habitat and ground cover
WildlifeDense turf provides habitat for ground-dwelling insects, earthworms, and beneficial soil organisms that support local ecosystems. [source]
Low-maintenance landscape alternative
HouseholdReduces need for pesticides and fertilizers compared to traditional turfgrass varieties, and requires less frequent mowing than cool-season grasses. [source]
Harvest Tips
Zoysia Emerald is a turf grass not harvested in the traditional sense. Maintain consistent mowing at 1-1.5 inches height throughout the growing season. Best appearance achieved with regular weekly mowing during active growth months (April-September). Avoid scalping or cutting below 1 inch to maintain density and health.
Fun Facts
- 🌱 Zoysia Emerald is patented and represents one of the finest-textured zoysias available, combining traits from two different zoysia species to create a superior hybrid.
- 🌱 Zoysia grass was originally introduced to the United States from Japan in the early 1900s and is named after the Zoysia genus, which includes several Asian grass species.
- 🌱 This grass creates its own pest deterrent: its dense growth and vigorous lateral spread naturally crowd out many weeds, reducing the need for herbicides.
