Till your topsoil using compost or fertilizer to turn the dirt at least 1 to 2 inches deep. Plant your monkey grass seeds in the soil in the early spring or early fall for the best results.
Place dividers into the soil around the area where you plant to grow the monkey grass. Make sure your dividers are at least 12 inches deep to prevent the monkey grass from spreading into areas where it is unwanted.
Plant the seeds by spreading half of them as you walk in one direction and the other half as you walk in a perpendicular direction. You may do this by hand or with a seed spreader.
Rake the seeds gently and cover the area lightly with a mixture of topsoil and compost. Scatter more monkey grass seeds on top of the area.
Water the area liberally after you plant the seeds. Water the seeds at most twice per week after they have been planted.
