Compost should be uniformly applied over the entire area at an average depth of 1-2 inches and then incorporated to a depth of 6-8 inches using a rotary tiller or similar equipment. Higher application rates of compost may be used if the compost is incorporated into a greater depth. Rake the soil surface smooth prior to seeding or planting. The soil surface should be free of large clods, roots, stones, and other materials that will interfere with planting. The amended area should be watered thoroughly after planting.
Maintenance: Annual topdressing with a finer grade compost is a good maintenance practice on both cool and warm season lawns. This can be done before or after core aeration to reduce compaction and improve moisture holding capacity. Drag or rake compost into the aeration holes. Cool season lawns can be topdressed in the early spring or fall. Its best to apply compost to warm season lawns in the spring just prior to the active growing season. The area should be watered thoroughly after and seeding.
