Texas covers a wide range of growing for being in a limited range of growing zones. Most of the state can grow a variety of grass seeds if done in irrigated areas; otherwise, grass seeds for the non-irrigated areas are limited to the eastern portion and the Gulf of Mexico.
Bermuda grass is a drought-resistant grass that needs full sun. This makes it a good grass seed for the desert areas of Texas. Caution should be used as this is an invasive and quick spreading grass once established. Purchase Bermuda grass as seeds or as sod on a pallet. It can handle cold and foot traffic but not shade. Watering is needed weekly to maintain the green color. Find use of this grass seed in zone 3 along eastern Texas and in irrigated areas of the remaining portions of the state.
Buffalo grass is another drought-resistant grass. This is the only grass seed native to Texas. Prairie grass is the original form of this type. Get Buffalo grass seed for the native variety only; any hybridized varieties are purchased as sod on pallets. The grass seed is much easier to find than the sod. Plant the seed in moist soil in the spring or early fall and summer. Little fertilization is needed for this grass type although it does require occasional watering. Find Buffalo grass seed useful in unirrigated areas of zones 2A and 3A along western Texas.
Find use of this grass seed in zone 3 along eastern Texas, zone 4 in the Gulf of Mexico and in irrigated areas of zone 3A in the western portion of the state. Centipede grass seed can be overseeded with cool-season grasses to maintain a green lawn over winter; combine this grass seed with rye grass for a good result. It can handle cold temperature but not below 15 degrees Fahrenheit. Use this grass seed in locations where St. Augustine grass has been adapted.
St. Augustine is one of the most used grass seeds and is often overused; this is likely because it can grow in both shade and sun. Heavy watering is required because of the hot summers in Texas. Watch for areas of standing water in low-lying areas where the grass can drown. Some of the other more common problems include white grubs, brown patch and chinch bugs. This grass is most often found in plugs or as sod on a pallet. Grow this grass in zone 4 along the Gulf of Mexico.
Plant this grass seed in lightly shaded areas with most recent hybrids staying green year-round. This is a drought-resistant grass but will need to be overseeded to provide full coverage to an area. Use this grass seed in zone 2A in well-irrigated areas up along the northernmost areas of Texas.
Zoysia grass seed wasn't available until 2001, but was found in sod pallets and plugs before that time. Because of the need to precisely follow seeding instructions, this is one of the more difficult grasses to grow from seed. Zoysia is a drought-resistant, full, sun-loving grass but does take long to grow and is not good for heavy foot traffic. This grass seed can be used in any location of zones 3 and 4 along the eastern side of Texas; use of this grass for the remaining portions is restricted to irrigated areas.
