How to install
sod, well.

Remove the existing lawn before preparing the soil. For persistent grass, the original A-G guide recommends treating active growth with a non-selective herbicide, waiting about two weeks, and checking for regrowth before removing dead material with a sod cutter.

If using herbicide, follow the product label and local requirements. Apply only in calm conditions and observe the label's irrigation, protective equipment, and re-entry instructions. Mechanical removal is another option.

Install or repair the irrigation system before laying sod. Aim for complete, head-to-head coverage so each sprinkler reaches the neighboring head. Check for leaks, blocked heads, and dry corners.

After soil preparation, clear debris from the heads and test the entire system again. Your irrigation should be ready to run as soon as installation begins.

Remove rocks and debris, then till the soil 6 to 8 inches deep. The original guide recommends organic amendments at 3 to 5 cubic yards per 1,000 square feet. Match amendments to your soil conditions and seek local advice if needed.

Grade for drainage, smooth the surface, and firm the soil. Keep the finished soil about 1 inch below walks and other hardscape to allow for the thickness of the sod.

Install immediately upon delivery. Start along a straight edge, fit the edges tightly without stretching or overlapping, and stagger the joints like brickwork. Use a sharp knife to trim around beds and obstacles.

Begin watering completed areas within 30 minutes rather than waiting for the whole lawn to be laid. Keep the sod from drying out, ensure good contact with the soil, and water thoroughly beneath the rolls.

Brown spots do not always mean the lawn needs more water. Check sprinkler coverage and use a screwdriver to inspect soil moisture 1 to 2 inches below the surface. Compare a dry or brown area with a healthy area before changing your schedule.

If the soil is moist but the grass is declining, disease or another issue may be involved. Avoid evening watering in hot summer weather and contact your nearest farm for help identifying the cause.
