Many homeowners prefer a lawn close to the house that may provide a recreational or play area for children or pets, a relaxing place for lawn chairs and family gatherings and to create a cooling effect. Lawns can be functional and their root mass provides erosion control and helps to filter, capture and break down pollutants. In fact, a practical sized lawn can be part of a Xeriscape, as long as it’s used sparingly and properly maintained.
To keep your lawn healthy this summer, follow the guidelines below.
- Water lawns only when they need it. If you leave footprints when walking across the grass, it may be time to water. Bermuda seldom needs water more than twice a week in summer.
- Water deeply. The water should soak down to at least 6 inches. Water lawns with pop up sprays once for 10 – 15 minutes, or break it into 2 or 3 short sessions spaced 30 minutes apart.
- Use a screwdriver to see how far the water is traveling. You can only easily push where soil is moist. If it’s hard to probe at 3 inches, run your sprinklers a few minutes longer.
- Check your irrigation system for leaks when it’s running and replace broken spray heads or risers.
- Let your grass grow slightly longer in summer. This protects the roots from heat stress by encouraging them to grow a little deeper and reduces water loss to evaporation by shading the soil.
- Instead of using a nitrogen based fertilizer, which increases growth, try water soluble (chelated) iron to green up the blades.
- If you have water pressure problems that don’t allow for good coverage or if you have compacted soil or a slope so that water runs off every time you water.
