Remove existing grass and weeds, loosen topsoil to a depth of 4-6 inches with a spade or rototiller. If topsoil is brought in, use a minimum of 3 inches and incorporate into existing soil. Level using a rake. If necessary, add dolomite or agriculture grade limestone at the rate of 50 lbs. per 1000 square feet. Rake and level simultaneously, roll the area lightly for a smooth surface. Prior to Turf installation apply starter fertilizer 16-16-16, following the directions on bag.
Do Not use weed and feed type fertilizer when installing. Rake area lightly and roll with lawn roller 1/3 full of water. This will firm the soil surface and reveal low areas which need to be filled in. Keep the grade 1/2 inch below sidewalks and driveways. Water the area to settle the soil and provide a moist base for the turf.
