Zoysia grass can survive severe winters, summers and irregular waterings. Zoysia is desirable because it can tolerate as much shade as St. Augustine and as much drought as Bermuda grass. Zoysia grass is disease resistant and traffic tolerant. It's slow growth means sod is preferred method of installation, however plugs can also be used if more time to develop a thick lawn is possible. Zoysia grass in general is slow growing and performs best with weekly mowing.
Emerald zoysia is a fine-textured hybrid zoysia that is possibly the most attractive of the zoysia grasses. It is well-suited for quality lawns where regular maintenance and care is provided. Emerald zoysia is less hardy but more shade tolerant than Meyer Zoysia.
Emerald zoysia is dark green with fine leaf texture, high shoot density and a low growth habit. If over fertilized Emerald zoysia will quickly develop excess thatch. Emerald zoysia is also subject to winter injury.
First introduced in 1955 by the United States Department of Agriculture and the Georgia Agricultural Experiment Station, Emerald zoysiagrass is a hybrid between Zoysia japonica and Zoysia tenuifolia. Emerald combines the fine texture of Zoysia tenuifolia with the cold tolerance with a faster rate of spread of Zoysia japonica. Emerald is similar to Zoysia matrella in appearance and habit.
Emerald zoysiagrass is highly recommended for top quality lawns where time and money allow for adequate maintenance. Emerald zoysia grass produces an excessive thatch layer and is susceptible to dollar and leaf spot. Brown patch disease also can occur.
