Winterizing Your Lawn

As temperatures begin to cool in the fall, you might be tempted to apply one last round of fertilizer to your lawn. But timing is important.

The last recommended time to fertilize your lawn in North Florida is in September. In Central Florida, October's the latest. A high-potassium fertilizer would be best for this time of year. Fertilizing too late could cause the grass to be growing when cold weather comes, making it more cold-sensitive.

If you missed your fall application, there's no need to worry. As growth begins in the spring, just apply an appropriate fertilizer for your lawn type, and your turf will respond with fresh growth and vigor. In some parts of South Florida, it's warm enough that your grass may grow—and need fertilizer—year-round.
