Prepare the site by grading so that the soil slopes away from foundations and buildings, thus avoiding drainage problems.
If renovating an existing lawn, destroy the current vegetation.
Using native soil only: Till to a depth of 4 to 6 inches, smooth the soil, remove rocks, roots, clods, and vegetation.
Using Soil3 humus compost: 1/2 to 2" of Soil3 should be mixed with the top layer of existing soil. Just raking the Soil3 into the existing top soil is usually sufficient. Smooth the soil, remove rocks, roots, clods, and vegetation.
If use a 1/2" layer of Soil3, 1 cubic yard will cover 2,000 sq. ft.
If use 1" layer of Soil3, 1 cubic yard will cover 1,000 sq. ft.
If use 2" layer of Soil3, 2 cubic yards will cover 1,000 sq. ft.
Water heavily to see if water puddles in any low spots, and if it does, add soil and/or regrade to eliminate low spots. Keep soil surface 1/2" below walks and drives. Tilled soil will settle some.
Our experience shows that no preplanting fertilizer is necessary when using Soil3. Apply and rake in dolomitic lime based on soil test results and/or according to the formulas below.
Centipede per 1,000 ft2: No lime necessary
All other turfgrass per 1,000 ft2: 50 lbs. dolomitic lime
