Emerald Zoysia is a cultivar of Zoysia grass with a thin bladed leaf that forms a very lush lawn. It shares the drought and shade resistance of the other varieties of Zoysia grasses.
This grass has as fine, soft texture and can be left unmowed as it only grows to a height of 6–12 inches (15–30 cm). When left unmowed, it forms a humpy convoluted surface which is sometimes used in oriental landscapes.
Emerald Zoysia is a very slow growing lawn grass. Zoysia grasses are generally slower growing than Bermuda and St. Augustine, with Emerald Zoysia being one of the slowest growing Zoysia grasses. The grass exhibits a dense
creeping growth, rather than an aggressive upward, or sprawling growth. The blade density is much higher than other grasses, giving a very dense, carpet-like, or "hedgehog" appearance.
Due to the density of the grass, excess thatch can accumulate and should be removed every several weeks. Mowing can be performed every 7-10 days, with no more than 1/3 of the blade cut at one time.
Recommended mowing height of this grass is between .75 and 2 inches (1.9 and 5.1 cm). Mowing the grass shorter than this height can produce a weaker less attractive product, whereas mowing the grass
higher than this height will promote a less-dense, wispy appearance. The use of reel mowers is suggested since common rotary lawn mowers will tear the fine-blade grass and leave a grey/white tip instead of a clean cut.
Emerald Zoysia has an adverse reaction to excessive fertilization, requiring no more than two light distributions per year. 8-8-8 or 13-13-13 fertilizer is recommended. If over fertilized, it will turn yellow and could die.
Since regrowth of this grass is slow, it's best to err on the light side of fertilization than to over fertilize.
