Our lawn is St. Augustine and it looks dead, accept for the weeds. Do we give it a little longer time or should we dig up and put in a new lawn. We have fertilized it but there is so few new grass we're not sure.

St. Augustine greens up according to air and soil temperatures. There's nothing you can do to make them green up faster in the spring but feeding in the fall months will help it endure the winter weather and green up as soon as the weather warms in the spring. It may be that your lawn needs dethatching. All turf grasses develop thatch, which is a layer of dead stems and stolons. If thatch gets too thick it can keep water and fertilizer from penetrating. Dig up a 6" square of turf and measure the thatch at the soil surface. If it's more than 3/4 of an inch, dethatching will remove the dead stuff and make room for new stems and leaf blades. A power rake or dethatcher will make quick work of the job. Then regular feeding, watering and mowing will help your lawn thicken up enough to crowd out most weeds. Spring is the best time to dethatch.
