Overview

Growing grass in Florida is much different than in the northern United States. Warm-season grass is predominant in Florida because of the warm, humid weather. Warm-season grasses require different fertilizing methods than cool-season grasses. By implementing proper fertilization techniques, you will be able to enjoy a lush, thick and green lawn in Florida.

Step 1

Apply fertilizer high in nitrogen, low in phosphorus and high in potassium. A good fertilizer mix would be 15-0-15, or 15-2-15. Florida soils already are high in phosphorus, so they don't need much.

Step 2

Fertilize at a rate of 1/2 lb. to 1 lb. of nitrogen per 1,000 square feet when your lawn starts growing in the spring. Slow-release fertilizer should utilize 1 lb. and water-soluble fertilizer should utilize 1/2 lb. Always read fertilizer instructions before applying.

Step 3

Reapply the fertilizer two to six times throughout the growing season. Grass in full sun would benefit from the higher number of applications, while shady locations should receive fewer applications.

Step 4

Stop fertilizing six weeks before the first frost to prevent the grass from being damaged by the frost. Damaged grass will resume growth much slower the following spring.

Step 5

Perform a soil test on your lawn annually. Contact your local cooperative extension service to receive instructions and supplies for taking soil samples. The soil sample will show you which components your lawn is lacking and which are abundant. This will enable you to apply the correct amount of nutrients.
