Most people assume that caring for a specialty turf variety means buying the most expensive bag on the shelf and hoping for the best.
Actually, maintaining a thick lawn requires matching the exact nutrient ratios to your soil's specific demands.
And finding the Best Fertilizers for Floratam Grass comes down to balancing nitrogen release with effective weed control.
Let us compare the top options so you can pick the right formulation for your yard.
Key Takeaways
- Prioritize fertilizers that contain controlled-release nitrogen to feed your grass evenly over several weeks without causing sudden, excessive top growth.
- Check the NPK ratio carefully because St. Augustine varieties thrive on specific proportions of nitrogen, phosphorus, and potassium.
- Select combination weed and feed products only when active broadleaf weeds or dollarweed are actively invading your lawn.
- Remember that newly laid sod or seeded patches require a higher phosphorus content to stimulate strong root development before greening up.
- Measure your total lawn square footage accurately to calculate the correct number of bags needed for proper coverage.

LESCO St Augustine Weed and Feed
Managing a Floratam lawn requires a careful balance of nutrient delivery and weed suppression, making this formulation the top choice for established properties. You get a targeted herbicide called penoxsulam that handles stubborn broadleaf weeds while simultaneously feeding the turfgrass. And the heavy-duty 50-pound bag provides enough coverage for large commercial or residential lots.
The main drawback is that you need to be cautious with application timing, because applying weed and feed products incorrectly can stress your grass. But when used according to the label instructions, the results speak for themselves through vibrant green color and aggressive weed control.

The bag is quite small at only three pounds, meaning you will need multiple bags for anything larger than a patch repair. But for new lawns, giving roots that initial jumpstart prevents costly replacement down the road.
