Clay soils needs quite a bit of water to soak down 12 inches deep. While many lawns look great even when watered only once every three to four days, really sand soils may need daily irrigation. Repeat cycles are best for this soil type and allow for deeper root watering and less runoff. Aeration A regular aerating schedule is important to the health of your lawn. Try to aerate 2-3 a year, especially in the spring and fall.
Clay soil has a tendency to become compacted, which prevents water from sinking into the ground.
Aeration breaks up the soil and allows water to penetrate. Don't forget to add some compost when you aerate. In particular dry areas, you can use a screwdriver to poke holes into the soil to help the water get into the ground. Mowing Height Set the blade height on your mower so that you keep the grass at a height of 3 inches. This shades the soil and prevents both excess drying and evaporation.
