Join us on this journey as we unlock the secrets to a flourishing St. Augustine lawn.

A Brief Overview

St. Augustine grass, scientifically known as Stenotaphrum secundatum, is a warm-season grass variety widely cultivated for lawns, pastures, and landscapes in regions with a tropical or subtropical climate. It is named after St. Augustine, Florida, where it was first introduced in the United States. St. Augustine grass is known for its lush green appearance and excellent heat tolerance, making it a popular choice for lawns in the southern United States.

Key characteristics of St. Augustine grass include:

  1. Appearance: St. Augustine grass features broad, flat blades that are dark green in color. It forms a dense, carpet-like turf when properly cared for.

  2. Growth Habit: This grass variety has a prostrate growth habit, spreading through above-ground stolons, which are horizontal stems that root at nodes and create new grass plants.

  3. Heat Tolerance: St. Augustine grass is highly heat-tolerant, making it well-suited for regions with hot summers.

  4. Shade Tolerance: While it prefers full sun, St. Augustine grass exhibits moderate shade tolerance, making it suitable for partially shaded areas.

  5. Salt Tolerance: It can tolerate salt spray and is often used in coastal areas where saltwater exposure is common.

  6. Moderate Cold Tolerance: St. Augustine grass is less cold-tolerant than some other grass varieties, which limits its growth in colder climates.

  7. Water Requirements: It has moderate water requirements and can withstand occasional drought conditions, but it thrives with regular watering.

  8. Maintenance: St. Augustine grass lawns require regular maintenance, including mowing, fertilizing, and weed control.

Overall, St. Augustine grass is valued for its ability to create a lush and visually appealing lawn in warm and humid climates. Its maintenance needs and specific environmental requirements make it essential for homeowners and landscapers to understand its characteristics and proper care to ensure a healthy and attractive lawn.

Importance of Weed and Feed Products

A beautiful lawn is a source of pride for homeowners, but achieving and maintaining that picturesque expanse of green requires more than just mowing and watering. St. Augustine grass, known for its lush appearance and tolerance to heat, can be a stunning addition to any landscape. However, it is not immune to common lawn issues, and that's where the importance of weed and feed products becomes evident.

Weed Killer For St. Augustine Grass

Weeds, with their unsightly appearance, can quickly diminish the visual appeal of your lawn. They compete with your St. Augustine grass for vital resources such as sunlight, water, and nutrients.  The best weed and feed for St. Augustine grass is applying weed control separately.  Combination products that contain weed and feed are not as effective as you may think.  By applying fertilizer and weed killer separately, much better weed control is achieved. We suggest using Celsius WG as your main weed killer product on St. Augustine grass.  Celsius WG covers a broad spectrum of weeds in your lawn.

Preventing Weeds

Effective weed control is not only about eradicating existing weeds but also preventing their seeds from spreading and taking root. Pre-emergent fertilizers tackle this with ease.  We highly recommend applying pre-emergent two times a year on St. Augustine grass.  

Pre-emergent fertilizer

Fertilizer for St. Augustine Grass

  • Weed and feed products are not just about weed control; they are equally focused on providing essential nutrients to your grass. This balanced nutrition promotes healthy growth, resulting in a thicker and more vibrant lawn.  The best fertilizer for St. Augustine grass consists of slow-release nitrogen, potassium, and minor nutrients such as manganese, iron, sulfur, etc.
  • Iron is the best fertilizer for yellow grass.  By adding small amounts of iron to your lawn with fertilizer, it will deepen the dark green color of your lawn.  
  • St. Augustine grass fertilizer should contain both nitrogen and potassium. Depending on state restrictions, phosphorous can only be applied if a soil test suggests it is needed.  Our 20-0-10 and 10-0-20 lawn fertilizer analysis are key blends for St. Augustine grass.  Both fertilizers contain iron which will prevent St. Augustine grass from yellowing.

    Conclusion

    It's important to choose the right weed and feed product for your specific lawn type, grass species, and regional climate conditions to maximize its effectiveness and achieve the desired results. Proper application, timing, and follow-up care are also essential for maintaining a healthy and weed-free lawn.
