Prepare for next year's lawn
-- Reseed. As long as you're in a region of the Midwest that still has a few weeks before the first heavy frost, it's a great time to reseed problem patches or lay new sod (left). Just keep your sod well-watered.
-- Fertilize. Feed your lawn to encourage good root growth. Even if you fertilized your cool-season grasses (such as Kentucky bluegrass, ryes and fescues) in September, it's a good idea to do it again in October to encourage faster greening in the spring. Now's also the time to fertilize warm-season grasses, such as bermudagrass, creeping bentgrass or zoysiagrass.
