Maintaining a lush green lawn is a task that every homeowner cherishes. St Augustine grass is a popular choice for southern regions due to its resistance to warm temperatures, but keeping it healthy can be quite challenging. That’s where fertilization comes in. In this ultimate guide to St Augustine fertilizer, we’ll help you choose the best fertilizer and give you tips on how to use it properly.

Why fertilizer is a must for vibrant, healthy St Augustine grass

Fertilizing provides necessary nutrients to the soil, which leads to abundant growth and improved plant health. St Augustine grass needs certain nutrients such as nitrogen, phosphorus, and potassium to thrive. Without these nutrients, the grass may become weak, thin, and susceptible to pests and diseases.

How different types of fertilizers work to improve the soil's nutrient content

St Augustine fertilizers come in various forms, including granular and liquid. Each type has its unique advantages and disadvantages. Granular fertilizers usually release their nutrients slowly over time and are easy to apply, whereas liquid fertilizers provide quick results and better absorption into the grass blades.

What you need to know before selecting a St Augustine fertilizer

Before choosing a fertilizer, you should determine your soil pH level and nutrient deficiencies. A soil test kit can help identify these factors. Additionally, consider the condition of your lawn, the climate, and your budget. It’s essential to purchase a high-quality fertilizer that suits your lawn and the frequency at which you’re willing to use it.

Types of St Augustine Fertilizer

Granular Fertilizers

Granular fertilizers consist of small pellets that are sprinkled over the lawn. They're easy to apply and can be distributed evenly. These fertilizers usually last longer and require fewer applications compared to liquid fertilizers. They’re a popular choice for homeowners who want to save time and effort.

Liquid Fertilizers

Liquid fertilizers are mixed with water and sprayed directly on the grass blades. They provide quick absorption of nutrients, but they might take some practice to apply properly. Liquid fertilizers are perfect for those who want immediate results or want to target specific areas with nutrients.

When to Fertilize St Augustine Grass

Spring Season

Spring is the best time to fertilize your St Augustine grass. It’s when the grass starts growing rapidly and needs high levels of nitrogen to produce healthy green foliage. If you missed the spring season, you can also fertilize during early summer.

Summer Season

During summer, the weather is hot and dry, making it difficult for St Augustine grass to retain essential moisture. Fertilizing in early summer can help replenish the soil's moisture content and provide necessary nutrients to help the grass thrive.

Fall Season

Fertilizing during fall helps prepare the lawn for the winter dormant phase, which starts in late November. During this period, St Augustine grass slows down its growth, and excess fertilizer could encourage fungal growth leading to further turf issues. So a moderate amount is ideal to strengthen roots during winter.

How Often to Apply St Augustine Fertilizer

Frequent Feeding with Small Amounts

Frequent feeding is the safest way to keep your lawn healthy. Instead of applying large amounts at once, it’s better to apply small amounts every six to eight weeks, depending on the fertilizer's brand and specifications.

Infrequent Feeding with Large Amounts

If you have a busy schedule or want to reduce costs, you can opt for infrequent feeding with larger amounts of fertilizer. However, this method increases the risk of overfertilizing your lawn and causing turf issues.
