When Should I Fertilize My Lawn in Florida

Timing Is Everything
Maintaining a lush, green lawn in Jacksonville takes more than just regular mowing and watering. One of the most common questions we get at Happy Lawns is: "When should I fertilize my lawn in Florida?"
In North Florida's subtropical climate, the ideal fertilization schedule is timed to your lawn's growing season. For warm-season grasses like St. Augustine, Bermuda, and Zoysia, fertilization should begin in early spring once the lawn starts to green up—typically around March.
Recommended Fertilization Schedule:
- Spring (March - April): Apply a slow-release nitrogen fertilizer to encourage healthy growth.
- Early Summer (May - June): Apply a second round to maintain vigor through the heat.
- Late Summer (August): Light feeding to sustain color and density.
- Fall (October): A balanced fertilizer with lower nitrogen to prepare the lawn for winter.
Why Professional Fertilization Works Best
DIY fertilizer products can cause more harm than good if misapplied. Our licensed technicians use the right blend at the right time to maximize turf health and minimize environmental impact.
