Factors to Consider When Choosing Best Fertilizers For Floratam Grass

NPK Ratio Balance

Floratam is a specific variety of St. Augustine grass that thrives when it receives a balanced nutrient intake. You should look for a fertilizer with an NPK ratio where the nitrogen content is slightly higher than the phosphorus and potassium. A 3-1-2 ratio is often the gold standard for promoting lush, green growth without forcing the grass to grow too quickly.

Nitrogen Release Speed

You need to decide between quick release and slow release formulations. Quick release nitrogen gives your lawn a sudden jolt of color, but it can easily burn the delicate blades of Floratam if you are not careful with your application rates. I suggest prioritizing slow release nitrogen because it feeds the roots steadily over six to eight weeks, which keeps your lawn healthy without the risk of an accidental chemical burn.

Iron Content

Floratam often struggles with iron deficiencies, which show up as pale or yellowing grass blades. Many premium fertilizers include chelated iron to help the grass maintain a deep, dark green color even when the soil pH is slightly off. Check the label for this specific additive, as it acts like a vitamin supplement for your lawn.

Soil pH Compatibility

St. Augustine grass prefers soil that is slightly acidic, generally within the 6.0 to 7.5 range. If your soil is too alkaline, your grass cannot absorb the nutrients you provide, no matter how much fertilizer you apply. Always check your soil pH first, as you might need a sulfur-based product to lower the pH before the fertilizer can do its job.

Application Method

Think about whether you prefer granular or liquid fertilizer. Granular options are easier to apply with a standard spreader and tend to last longer in the soil. Liquid fertilizers work faster but require more frequent applications, making them a better choice if you have a small lawn or need a quick recovery after a dry spell.

Frequently Asked Questions

How often should I fertilize my Floratam lawn?

You should aim to feed your lawn during the active growing season, which usually falls between late spring and early autumn. Applying fertilizer every six to eight weeks provides enough nutrients to keep the grass thick and resilient. Stop the process once the temperatures consistently drop, as the grass enters dormancy and does not need the extra fuel.

Can I use a weed and feed product on Floratam?

Be very careful here, as many common weed killers are toxic to St. Augustine varieties. Always read the label to ensure the product is specifically labeled for Floratam or St. Augustine grass. If you use a broad-spectrum herbicide, you might end up with more brown patches than weeds.

Does Floratam need more water after I fertilize?

Yes, you should always water your lawn thoroughly immediately after applying granular fertilizer. This helps wash the granules off the blades and into the soil, which prevents them from scorching the grass. Aim for about one quarter-inch of water to ensure the nutrients reach the root zone.

Why is my Floratam turning yellow despite regular fertilizing?

Yellowing is often a sign of an iron deficiency or soil that is too alkaline. If you have been fertilizing regularly and the color does not improve, consider a soil test to check the pH levels. Adding a liquid iron supplement often resolves the color issue within a few days.

Is it possible to over fertilize Floratam?

Absolutely, and doing so can lead to a buildup of salts that damage the root system. Stick to the manufacturer recommended application rate on the bag, as more is rarely better. If you see the edges of the grass blades turning brown or crunchy, you have likely provided too much nitrogen and need to flush the area with water.
