There are several grasses that grow well in Florida. St. Augustine, Bermuda and Centipede grasses all do well in warm climates, while tall fescue and rye grass are better for the cooler areas of the state. Installing or growing these grasses doesn't vary too much, but there are some differences.
Choose a type of grass that is best suited to your area. Bermuda likes the heat found in the southern part of the state, but doesn't do well in shade. Centipede likes the heat as well and is better in shade, but does not handle it as well as St. Augustine, which also likes the heat. Fescue is better in the northern area of the state than in the southern part. It burns easily and prefers some shade. If you are near the coastal areas, you might try seashore paspalum, which does well in areas where salt is prevalent.
Aerate lawn to create holes for new grass and break up old, or use a rototiller to turn the soil.
Spread the grass seed over the lawn with a spreader or by hand. Use a coated seed, if possible, to keep birds at bay.
Lightly cover seeded area with straw. Not too much or you may have a problem with it breaking down or removing it.
Water the lawn daily if it isn't raining. Fifteen minutes in each area is enough. Water in early morning so the water will be able to soak in the ground before the heat of the day. Watering at night is not good, since it can promote mold growth.
