Low Maintenance, Drought-Resistant Lawns

According to a NASA study on lawns, approximately 50,000 square miles of grass covers the U.S, which the Environment Protection Agency (EPA) estimates accounts for one third of Americans' water usage. In addition, 95 percent of the 50,000 square miles of greenscape consists entirely of thirsty bluegrass. Although there are numerous environmentally-conscious alternatives to grass lawns like xeriscaping or rock gardens, there are also many types of low-maintenance, drought-resistant grasses available for those who insist on having a green lawn. Here are just a few to choose from:

Bahia grass: This is an ideal choice for infertile soil. It grows very coarse and thick and needs a lot of sunlight. It grows best in warm humid regions, specifically Florida.

Bermuda grass: Bermuda soaks up the sun and responds well to watering. It responds well to traffic, but needs to be mowed frequently. This grass is adapted to tropical and subtropical climates.

Buffalo grass: This midwest prairie native needs full sun exposure. It does not do well with heavy traffic, but can tolerate cold weather well. Most varieties are drought resistant.

Fescues: These are cool season grasses that do well in northern climates. It is shade tolerant and absorbs water well after drought.

St. Augustine grass: This robust grass is adapted to moist, coastal areas with high summer temperatures and mild winter temperatures. It tolerates moderate shade along with a wide range of soil types.

Zoysia grass: Zoysia is very flexible and durable, while having the ability to tolerate traffic. It grows slowly, but does well in the sun or shade. It adapts particularly well along the Atlantic and Gulf Coasts.

Before making the switch, research how these grasses would survive in the climate you live in. Also, wait until fall or spring to make any big changes to your yard.

Limiting the use of residential lawn sprinklers is another environmentally-friendly tactic you can easily adapt to. See how water restrictions have proven effective in Los Angeles, CA.
