When Should I Fertilize My Lawn?

When to fertilize your lawn depends on a few things, but the biggest rule is to fertilize only when your lawn is actively growing.

In South Florida, turfgrass grows year-round, while in North and Central Florida, it grows from roughly March or April through September, October, or November.

The maintenance plan you choose also influences when to fertilize. If you choose a higher maintenance plan, you’ll fertilize more times during the growing season, while a basic plan will require fewer applications.

Look for a fertilizer with at least some slow-release nitrogen, which releases the nitrogen to the grass over an extended period of time.

And finally, be aware of state and local regulations that cover lawn fertilization, and be sure to adhere to them.
