Floratam grass can suffer from too much fertilizer just as readily as too little. Its fast, hungry growth may tempt you to add extra nitrogen, but excess feeding can invite weak growth and turf stress.
That makes the Best Fertilizers for Floratam Grass less about the biggest N-P-K number and more about matching timing and coverage. The ten options below offer different approaches, so keep reading to compare their intended uses.
Key Takeaways
- Choose an N-P-K ratio that supports steady leaf growth without applying excessive nitrogen to Floratam.
- Check the listed coverage area and match it to your lawn size to avoid under- or over-application.
- Pick liquid fertilizer for quick, flexible feeding, or granular fertilizer for slower, more measured distribution.
- Look for added iron if deeper green color is a priority, but follow label rates carefully.
- Select starter, weed-control, or insect-control formulas only when that specific lawn need is present.

Frequently Asked Questions
What N-P-K ratio is best for Floratam grass?
There is no single best ratio for every lawn. A fertilizer with higher nitrogen and modest phosphorus often suits actively growing Floratam, but a soil test gives you the most reliable target. Look for a product that also supplies potassium when your soil is deficient. Potassium supports stress tolerance, but adding it without a soil need usually provides little benefit.
How often should you fertilize Floratam?
During active growth, many lawns need feeding about every 6 to 10 weeks, depending on the product's release rate, soil fertility, rainfall, and local guidance. Always follow the label's annual application limit. Reduce or stop applications during dormancy, drought, or extreme heat. Fertilizing stressed grass can cause injury instead of greener growth.
Can you use weed-and-feed on Floratam?
You can use one only if the label specifically lists St. Augustine or Floratam and gives clear application directions. Floratam may react poorly to certain herbicides, especially during hot or dry conditions. A separate fertilizer and targeted weed treatment often gives you better control and lower risk. Never exceed the label rate or apply herbicide to drought-stressed turf.
Is liquid or granular fertilizer better for Floratam?
Both can work well. Granules usually offer longer feeding and easier lawn-scale coverage, while liquid products provide quick, even distribution when mixed and applied correctly. Choose granular for routine maintenance across a large yard. Liquid is convenient for smaller areas, but you must measure the concentrate carefully to avoid overapplication and leaf burn.
Should you water Floratam after fertilizing?
Follow the product instructions. Granular fertilizer commonly needs light watering to move nutrients into the soil and off the leaf blades, while some liquid products are designed to remain on the foliage for a specified period. Do not apply before heavy rain, and avoid creating runoff toward drains, ponds, or sidewalks. Sweep stray granules from hard surfaces and water only as directed.
