What is the Best Fertilizer for St. Augustine Grass

If you live in the South, chances are good you have St. Augustine grass (Stenotaphrum secundatum). This common turfgrass is known for its thick, coarse blades and dark green color. It’s a tough grass that can withstand high traffic and heat, making it a popular choice for home lawns.

When it comes to fertilizing St. Augustine grass, there are a few things to keep in mind. First, this grass is a heavy feeder, so it needs plenty of nutrients to stay healthy and look its best. A good fertilizer will contain nitrogen, phosphorus, and potassium – the three main nutrients that all plants need for growth.

Second, because St. Augustine grass is prone to developing thatch (a layer of dead organic matter that accumulates on the soil surface), it’s important to use a fertilizer that contains slow-release or controlled-release ingredients. This type of fertilizer will release nutrients slowly over time, preventing them from being quickly used up or leached out by rainfall or irrigation before they can be taken up by the roots. Third, because this turfgrass grows best in warm weather, it’s important to choose a fertilizer with an “ Summerguard ” formulation designed specifically for use during the summer months .

This type of fertilizer will help your St. Augustine grass resist stress from heat and drought while promoting strong growth during the active growing season .

First, make sure to mow your lawn regularly so that the weeds don’t have a chance to flower and produce seeds. Second, use an appropriate herbicide for the type of weed you’re trying to control.
