Answer: Fall is an excellent time to do some renovation. The soil under your lawn can become compacted from foot traffic, and compacted soil excludes air (which roots need). You can fix compacted lawns by aerating every 2-3 years in either the spring or the fall. If you rent a power aerator, it will dislodge plugs of soil. Leave the plugs on the lawn (they'll decompose and break down in the rain). After aerating, spread a thin layer of sand or organic mulch over the top of the lawn and then water deeply. You can overseed your lawn as late as October, or you can wait until April to broadcast fresh seeds over the entire lawn area. In the warm spring weather the grass seeds should sprout in 7-10 days. By early summer you'll have a thick, lush lawn.
