Emerald Zoysia Growth Rate

Description

• Emerald zoysia has a fine texture, grows well in full sun, and is tolerant of cold weather and shade. Its dark green color may turn brown during its wintertime dormant phase but it will green up again once seasons change. Recommended regions for planting zoysia are U.S. Department of Agriculture hardiness zones 6 through 9. Although it is resistant to wear and tear, it may not be the best turf for high-traffic areas because it is so slow to grow and can take a long time to fill holes. Also, zoysia grass tends to accumulate thatch, so occasional aeration and dethatching is necessary. It is best to grow Emerald zoysia only if an adequate maintenance program will be adhered to.

Rate of Spread and Growth

• Emerald zoysia and other zoysia grasses are slow to spread, extending itself as little as 2 to 5 inches per year if conditions are not perfect. Although Emerald is somewhat quicker growing than other zoysia, it can still take a year or more to establish a lawn. Sprigs or plugs planted 6 inches apart can take 12 months to two years to completely fill in but may spread faster if well cared for. Emerald zoysia will reach only 6 to 12 inches in height but is best mowed down to about 1 inch. If you're eager to quickly fill your lawn with grass, zoysia may not be the best choice for you unless you fill the entire lawn with sod. Seeds are usually not available and may not grow the first year.

Planting Method

• Prior to planting, remove weeds and rake the seedbed until it is smooth, breaking up all clumps of soil. Transplant sections of sod, plugs or sprigs to establish the grass. Sodding provides an instantaneous lawn that just needs water and time to root into the ground. Plugs are usually planted 6 inches apart and fill in completely after one or two years. Sprigging is a more laborious method of establishment. Plant sprigs no more than 6 inches apart in rows 6 inches apart.

Maintenance

• To speed up growth rate, continuous and appropriate maintenance is necessary. Apply 1 to 1 1/2 inches of water per week, although zoysia is drought-tolerant and will survive with less than 1 inch of water per week. To maintain dense, fast-growing turf, apply a nitrogen fertilizer a minimum of three times a year, in April, June and August. Mow regularly every 10 to 14 days for most lawns or more frequently for golf courses and sports fields.
