|Think of December as a continuation of your lawn care duties from the previous month. Continue mowing your lawn on a regular basis if it needs it. If you have a mulching mower use it clean up any buildup of leaves that your trees have - you'll be able to use the leaf shreddings as organic compost for your lawn. Before you mow your lawn next time, raise the deck height of your mower to a height of at least three inches. The rule is: two inches for warm season grasses and about three to four inches for cool-season grasses. If rainfall equals less than an inch a week, water your lawn. Hold off on fertilizers until spring growth begins. Start by overseeding the bare areas, then wait until you've mowed the lawn 2-3 times to allow the new grass to develop a healthy root system. After you've mowed 2-3 times you can feed and apply a weed killer. Use a product such as Scotts Turfbuilder Plus Halts. It will feed your lawn plus in contains a pre-emergent herbicide which will help keep weed seeds from sprouting. Hope this answers all your questions. Best wishes with your lawn.
