The #1 rule: fertilize only when grass is actively growing
Fertilizing during dormancy (or when growth is slow) wastes product and can increase runoff risk. In much of Central and North Florida, the strongest growth is typically spring through early fall.
A simple schedule most homeowners can follow
- Spring: first application after green‑up.
- Summer: 1–2 applications depending on turf health.
- Early fall: last “growth season” application.
South Florida lawns often grow more consistently—use lighter applications and watch for disease pressure in humid months.
How much to apply (homeowner-friendly)
- Measure your lawn (square footage matters).
- Read the label (Nitrogen is the first number in N‑P‑K).
- Go reasonable (over‑nitrogen can increase disease and insect pressure).
Green without forcing growth: In peak summer heat, iron products can darken color without pushing extra growth.
Choosing the right fertilizer
- Slow‑release nitrogen is usually steadier and safer.
- Low/no phosphorus is often appropriate unless a soil test says otherwise.
- Match the turf (St. Augustine, Zoysia, Bahia, etc. have different needs).
Application best practices
- Don’t fertilize right before heavy rain.
- Keep granules off sidewalks/driveways—sweep, don’t rinse.
- Water lightly after application (enough to move product into soil).
- New sod: wait until roots start establishing before pushing fertilizer.
