St. Augustine grass thrives in well-drained soil and imparts an appealing blue-green tone to lawns. Although it prefers sunny areas, it tolerates a bit of shade. While this vining-type grass spreads rapidly, it can grow a bit spindly if the soil doesn’t have adequate nutrients, which is the case with a lot of sandy soils in the coastal states.

N-P-K Ratio

Lawn and turf fertilizers are labeled with the amounts, by weight, of three specific nutrients they contain: Nitrogen (N) brings out the color in the grass and speeds growth, phosphorus (P) encourages bud and seed formation, and potassium (K) encourages healthy plant growth. While all three are required for St. Augustine grass to grow well, the nutrient that soils lack most is nitrogen.

St. Augustine grass usually contains more nitrogen than phosphorus and potassium. A typical turf fertilizer formulation, for example, has an NPK ratio of 15-1-5. As you browse lawn fertilizers, you’ll notice how many different NPK combinations they offer, but nearly all of them are highest in nitrogen.

Liquid vs. Granular vs. Water-Soluble

Lawn fertilizers are made in three main formulations: liquid, granular, and water-soluble. There’s no “right” option here—the form of fertilizer that’s best for your lawn is mostly a matter of personal preference.

  • Liquid: For a quick boost of growth, many growers and groundskeepers opt to apply liquid lawn fertilizer because it’s quickly absorbed through the blades of grass and immediately goes to work, encouraging new growth. Results can be seen in as little as 3 or 4 days after applying liquid fertilizer to St. Augustine grass. The product can be purchased either full strength or in a liquid concentrate for diluting and applying via a pump-type garden sprayer. The caveat with liquid fertilizers is that they quickly pass through and out of the lawn, so they may need to be applied more frequently than granular types.
  • Granular: Resembling tiny grains, granular fertilizers contain many of the same nutrients that liquid fertilizers contain. They differ slightly in that granular fertilizers are often released more slowly, which means the grass’s roots can access the nutrients over an extended period. Granules won’t give you the same rapid greening-up that liquid fertilizers will, but they typically require less frequent application. Granular fertilizers are applied to the lawn using a spreader.
  • Water-Soluble: Though this fertilizer comes in a granular form, it’s not meant to be applied with a spreader. Instead, water-soluble fertilizers are made to be applied using a hose-end dispenser that connects to a garden hose. The water flows through the dispenser, dissolving and diluting the granules and dispersing the fertilizer via a hand-held sprayer. Like liquid fertilizer, water-soluble fertilizer can green up the lawn fairly quickly.

Organic vs. Synthetic

Most lawn fertilizers contain chemical and synthetic ingredients, but a few are made from all natural components.

Organic: Natural organic fertilizers contain the same nutrients as synthetic fertilizers, but they come from natural sources, such as earthworm castings and composted manure. They’re usually more expensive than synthetic formulations because it takes more work to gather the ingredients and process them into fertilizer. The upside is that organic fertilizers are eco-friendly and unlikely to pollute waterways or harm aquatic life.

Synthetic: Chemicals made in a laboratory to mimic the nutrients found in nature are the main components of synthetic fertilizers. Depending on the product, synthetic fertilizers may also be enriched with essential minerals found in healthy soil, such as calcium, magnesium, or boron. While lawns will react to both types of fertilizers favorably, the high nitrogen content in some synthetic fertilizers can harm aquatic life if it runs off in waterways.

Application

Knowing when to fertilize is just as important as using the right fertilizer. St. Augustine grass should be fertilized for the first time in spring only after turning fully green. Fertilizing it before that time may damage the grass. Apply an all-purpose lawn fertilizer that’s high in nitrogen at the rate recommended on the package. After that, St. Augustine grass should be fertilized every 6 to 8 weeks, depending on the product’s recommendations.

St. Augustine grass doesn’t grow well from seed, so it’s usually propagated through sod or plugs. When starting a new lawn of St. Augustine, apply a lawn starter fertilizer that offers a balanced ratio of nutrients, such as 10-10-10, to the ground beneath the sod. As the roots grow downward, the fertilizer will be absorbed and boost plant health.

A high-nitrogen fertilizer can be applied a month later, followed by periodic applications during the growing season. Stop fertilizing in the fall approximately 1 month before outdoor temperatures drop to around 55 degrees Fahrenheit. At this temperature, St. Augustine grass goes dormant, and won’t need any fertilizer until spring.

Our Top Picks

St. Augustine grass looks its best when it gets all the nutrients it needs, which is why periodically applying a general lawn fertilizer will increase the lawn’s lushness—and the chances that you’ll have a uniformly green lawn. Choosing between liquid, granular, and water-soluble is mostly a matter of personal preference. These lawn fertilizers are all suitable for boosting nutrients in a St. Augustine lawn and keeping it looking lush.
