Fertilizing A slow-release fertilizer is the best choice for lawns. Use a slow-release inorganic or an organic fertilizer such as Milorganite. Here's how many pounds of Milorganite to use per 1,000 square feet. If you choose another fertilizer, the amount to use is most likely listed on the bag's label. If not, adjust the amount in proportion to the percentage of nitrogen, the first number listed in the product analysis.
Seed Buy only top-quality seed.
It will cost a bit more, but is a small part of your investment in your lawn. The highest-quality seed is free of weed and other undesirable crop seed. If your lawn is Bermuda-grass or zoysiagrass, you might want to sow seed now for an attractive winter lawn while the permanent lawn is dormant. The best time is before the summer grass is fully dormant, usually mid-October. Use the fast-germinating perennial ryegrasses.
