Take good care of your lawn in the fall, and it will look great in winter, spring and summer. Here are the basics on fertilizing, watering, mowing, aerating and over-seeding.
STEP 1: Fertilize cool-season lawns such as bluegrass, fescue and ryegrass with a complete fertilizer (containing nitrogen, phosphorous and potassium). STEP 2: Water less as the weather cools or rains increase, but don't let the lawn go completely dry. If necessary, adjust automatic timers to water less often. STEP 3: Mow the lawn when it's one-third higher than the recommended mowing height for that type of grass (see the Related eHows). STEP 4: Leave the clippings on the lawn. They'll add nutrients as they break down. STEP 5: Aerate cool-season lawns to improve water penetration and reduce thatch. STEP 6: Encourage dormancy of warm-season lawns like Bermuda grass, zoysia grass and St. Augustine grass by cutting back on water and not fertilizing. Mow as necessary. STEP 7: Renovate cool-season lawns that have been doing poorly (see the Related eHow). STEP 8: Over-seed warm-season lawns with ryegrass or tall fescue to keep them green in areas where winter is mild (see the Related eHows). STEP 9: Rake up fallen leaves so they don't smother the grass.
