§ Reduce thatch and compaction.
§ Reduce or eliminate nitrogen fertilizer and increase potassium fertilizer.
§ Water the lawn late at night or early in the morning.
§ Water infrequently and deeply.
§ Sharpen your mower blade two or three times per season.
§ Mow often so you never remove more than the top third of grass blades.
§ Leave clippings on the lawn.
§ Avoid using herbicides and pesticides.
§ Spread bird netting under your trees with falling foliage. After the leaves have dropped, gather up the corners of the net and drag away the leaf pile.
When watering lawns, wet the soil to a depth of about 8–10 inches. Watering less will encourage shallow rooting and result in a lawn that needs more frequent watering. Water applied deeper than 10 inches is beyond the reach of most grass roots, especially in sandy soils.
Check water penetration by probing the soil with a stiff wire or long screwdriver. The probe will pass easily through wet soil and become more difficult to push when it reaches dry soil.
Many sprinklers apply water faster than the soil can absorb it, and the runoff is wasted in street gutters. If this happens, water in short intervals, turning off sprinklers for 10 to 15 minutes in between so the water can soak in. You can also ask an irrigation specialist about low-precipitation sprinklers, which apply water at a slower rate.
