When Should You Fertilize Your Florida Lawn?

Applying lawn fertilizer

The best time to fertilize your lawn is when the grass is actively growing. In North and Central Florida, this growing season is from early spring, starting in April, until mid to late fall, and ending in November. Turf grass grows year-round in South Florida, so any time of the year is technically a growing season.

It is not recommended to fertilize your lawn during dormant months or before heavy rain or storm

How To Know If Your Lawn Needs To Be Fertilized

There are several telltale signs that your lawn needs to be fertilized as a result of a nitrogen deficiency, which include:

  • Yellow or yellow-green blades of grass
  • Slow growth
  • Thin patches
  • Low grass density
  • Grass patches in the shape of rings, with dead or light-colored grass in the middle
  • Rust-colored marks on your grass
  • And more!

If you see any of these signs, your lawn will benefit from a fertilization treatment. Aside from these visual cues, pH soil testing is the ideal way to tell if your lawn needs to be fertilized. Testing will determine how much nitrogen is present in your soil and how much fertilizer needs to be added for optimum health and a greener Florida lawn. 

How Often Should You Fertilize Your Lawn?

A slow-release nitrogen granular fertilizer should be applied 2-3 times a year. Florida lawns can be fertilized every 6-8 weeks during the growing season, varying depending on where you live. 

What Time of Day is Best to Fertilize Your Lawn?

The time of day is an important consideration in your fertilization plan. It is recommended to fertilize in the morning before the day becomes too hot.

Should You Fertilize Your Lawn Before or After Mowing?

Fertilize right after mowing your lawn so that the fertilizer has the most time to break down into the soil before you cut again. You should consider leaving the mulched grass clippings to break down into the soil and further improve the soil’s structure and resiliency.

Should You Water Your Lawn Before Adding Fertilizer?
