Mid-May through late June is the best time to plant warm-weather grasses. According to Kansas State University, warm-weather grass seed such as Buffalograss, Bermudagrass and Zoysiagrass will become established in the lawn when planted and irrigated during the summer months. The overall goal is to fully establish the grass prior to winter's arrival. Preparation of the new lawn seedbed must begin a few weeks before the grass seed planting dates.
Conduct a soil test of the summer grass planting area. Take several soil samples from a few locations. Mix the soil together. Allow the soil to fully dry. Deliver the soil sample to your local agricultural extension service. Tell the extension service agent the type of warm-weather grass seed to be planted in the new seedbed. The final analysis may take up to three weeks to complete.
Apply the recommended lawn fertilizer and agricultural lime to the grass planting area. Work the soil amendments into the ground to a final depth of 6 inches using a rototiller.
Rake the freshly tilled soil with the garden rake. Remove all rocks and foreign debris from the soil. Grade the ground as level as possible using the rake.
Broadcast the warm-weather species grass seed onto the prepared seedbed. Rates of seed will depend on the analysis from the soil test. Generally the seed will be spread between 1.5 lbs. to 3 lbs. per 1,000 square feet of area.
Run the tines of the garden rake over the freshly spread seed. The action of the tines will cover most of the seed with soil.
Irrigate the seedbed with the garden hose and sprinkler attachment. Soak the seedbed to a depth of at least 5 inches. Keep the new seed moist, but not overly wet where the soil begins to puddle water. The grass seed will begin to germinate in five to 15 days, depending on the grass species.
