Till the garden area to break up the first 4 to 6 inches of top soil. Dig up any weeds that are growing in the area.
Apply a starter fertilizer high in phosphorous to contribute nutrients to your grass seedlings for quick root development and growth. Use a starter fertilizer with a NPK 5-10-5. Distribute at a rate of 20 lbs. per 1,000 square feet of soil space. Work into the first 4 to 6 inches of top soil.
Water the soil until moist. Pour grass seed into a seed spreader. Push the seed spreader back and forth across the lawn to achieve an even application.
Spread 1/8 of an inch of compost over the seeded area and water. The compost keeps the seeds moist and contributes extra nutrients for their growth.
Water the lawn to moisten the soil. Keep the soil moist until seedlings have emerged or for the next week by applying water several times a day.
