5 Best Fertilizers for Floratam Grass in 2026 (Buyer’s Guide)

Many property owners treat Floratam the same way they treat common Bermuda, applying heavy nitrogen doses that trigger disease or invite chinch bugs.

Choosing the right Best Fertilizers for Floratam Grass requires understanding this specific St. Augustine cultivar's intolerance for harsh chemicals and iron imbalances.

Let us break down the top formulas so you can feed your turf correctly this season.

Key Takeaways

  • Prioritize fertilizers containing controlled-release nitrogen to prevent sudden, weak growth spurts that attract pests.
  • Check the phosphorus ratio carefully, because established Floratam usually requires very little of it compared to potassium.
  • Select formulations with built-in herbicides only if you have an active weed infestation that requires simultaneous treatment.
  • Verify that the iron content is safe for summer applications to avoid burning your delicate green blades.
  • Match the application method, such as liquid hose-end sprayers or granular spreaders, to your lawn size and comfort level.
