Warm Weather Landscape Tips

Set your mower at the proper height.

Here are tips to manage your water bill and keep your yard healthy while still complying with watering restrictions during the hot months.

Take a Day Off

One way to keep your water bill down during peak temperatures is to cut one watering day per week out of your daily sprinkler schedule. Taking just one day off can reduce your water use by as much as 10 to 15 percent.

Time of Day Watering Restrictions

Water in early-morning hours before sunrise to lessen water lost to evaporation and daytime winds. Mid-day watering is prohibited from 11 a.m. to 7 p.m. from May 1 until Oct. 1.

Plant Selection

Choose plants that are native to the arid climate of Southern Nevada and require less water and time. There are a variety of low maintenance plants which will add both color and vibrance to your landscape. bermuda and other warm-season grasses require about one-third less water than tall fescue grass.

Upgrade Your Irrigation Clock

Replace your irrigation system with a "smart clock" and save water and money. The Southern Nevada Water Authority offers an instant rebate coupon for smart irrigation controllers and rain sensors that automatically shut off your irrigation when it rains.

Mow

Each time you mow the lawn, change directions. Set your mower to the proper height to promote a healthy lawn and to reduce water use. Recommended mowing heights are 2 1/2" to 3" for tall fescue and 3/4" to 1 1/2" for bermuda.

Hand Water Brown Spots

Hand water brown spots and check your irrigation system. Lawns usually develop brown spots because of faults in the sprinkler system, such as mixed types of sprinkler heads, blocked spray patterns and improper spacing between sprinklers.

Check that your sprinkler heads are level to grade, perpendicular to the slope of the lawn and not watering sidewalks, walls or patios. If grass blocks the spray, trim around the sprinkler head or install a taller 3- or 4-inch pop-up.

Lawn sprinkler heads should provide "head-to-head" coverage. That means the spray of one sprinkler should reach the head of the adjacent sprinkler. If your lawn looks great except for stressed areas in front of the sprinkler heads, the heads are too far apart. A device called an undercut nozzle can help. Talk to an irrigation specialist if you decide to change out the nozzle.

Watering system pressure also can cause brown spots. Misting and excessive drift are signs of high pressure. Low pressure displays itself with weak, short spray patterns and reduced coverage.

Combat Compacted Soils

Compacted soils also can stress your lawn. Sometimes simply aerating a stressed area and giving it a good soaking solves the problem. Purchase a hand-operated coring aerator at a nursery, or hire a professional to do the job. Aeration should be done at least twice a year.

An extremely dry lawn becomes hydrophobic, or water-repelling. Add a tablespoon of liquid soap to a gallon of water and drench the dried area. This breaks down the surface tension of the grass, making it hydrophilic, or water-loving. Then give it a good soaking.

Leaf Scorching and Burning

Leaves usually are stressed for one of two reasons: improper watering or improper fertilization. Since both overwatering and under watering can damage plant leaves, the best solution is to water deeply and infrequently. This allows oxygen in the soil, washes salts away and encourages deep rooting.

For most trees and shrubs older than three years, water deeply once every seven to 10 days. Newer plants may need water twice as often until established. Add a layer of surface mulch 2- to 4-inches thick to conserve water between waterings and cool and enrich the soil.

Make sure you have the right fertilizer both for your specific plants and for the time of year. Some fertilizers release much faster in hot weather, increasing the potential for damage. Follow package directions exactly and err on the conservative side. Then, irrigate well to move nutrients to the soil.
