If not done in September, fertilize lawns with a slow-release, organic fertilizer with a 4-1-2 or 3-1-2 ratio. The final application of high-nitrogen fertilizer should be applied in November. This late treatment will help the grass to green up faster in spring.

Continue to mow lawns at 2½ to 3 inches. Grass clippings may be added directly to compost heap. Avoid adding soaking wet clippings to compost.
