Liquid Fertilizer vs Granular Fertilizer: Florida Comparison

Lawn Care · Features, terms and questions for your Florida project

What to Compare

Florida lawn fertilization is regulated (summer phosphorus and nitrogen bans in 20+ counties) and the right product depends on the season. Most FL lawn-care pros use BOTH: granular as the base, liquid as a tactical boost.

Head-to-Head Breakdown

Liquid Fertilizer

Features and considerations

  • Even coverage when sprayed
  • Easy to combine with iron, micros, or fungicide in one tank

Limits and questions

  • Requires sprayer + understanding of dilution ratios
  • Risk of burn if applied in hot midday sun
  • Most FL counties ban high-N liquid June–Sept
Granular Fertilizer

Features and considerations

  • Easier DIY — spread with rotary spreader, water in
  • Less burn risk when watered in immediately

Limits and questions

  • Uneven application risk (spreader stripes)
  • Requires watering-in or rain to activate
  • Can wash out in heavy summer storms
  • Some formulas burn if applied to wet grass

Frequently Asked Questions

Can I do both?
Compare Liquid Fertilizer and Granular Fertilizer on cost per season, results timeline, feeding duration per app, using the actual models or local proposals. Ask for supporting documentation and a written explanation of how the proposed option meets your needs.
What about during the FL summer fertilizer ban?
Many FL counties (Charlotte, Lee, Manatee, Sarasota, Pinellas, Hillsborough, Orange, etc.) restrict phosphorus and high-nitrogen fertilizer applications June 1 – September 30. Slow-release granular at 0-0-X (potassium-only) is generally allowed; liquid high-N is banned.
Is St. Augustine grass picky about which type?
St. Augustine responds well to both — it's a heavy nitrogen feeder. Bahia and Zoysia tolerate leaner programs.
Which is better for a brand-new sod install?
Granular starter fertilizer (high phosphorus, like 18-24-12) at install time, then granular maintenance feeds for the first year. Liquid feeds can be too aggressive for newly rooting sod. After year 1, switch to your normal program.
