But how exactly do you maintain St. Augustine grass to achieve this picture-perfect lawn? Here’s your guide to thriving St. Augustine Grass its care and maintenance.
Why St. Augustine Grass?
St. Augustine grass is uniquely suited to Houston’s climate. Known for its:
- Superior shade tolerance: Thrives even in partially shaded lawns.
- Heat resilience: Perfectly adapts to hot, humid Texas summers.
- Rapid establishment: Quickly creates a dense turf that crowds out weeds.
Essential Care Tips for St. Augustine Grass
1. Proper Mowing Practices
- Ideal Height: Ideally, you want to mow keep your St. Augustine grass at a height of 3–4 inches for optimal health. Cutting it too short can stress the lawn, encourage weeds, and make it more susceptible to disease. If your lawn grows a bit too tall, it can handle occasional heavy mowing where more than one-third of the blade is removed, but avoid making this a habit as it weakens the turf over time.
- Sharp Blades: Dull mower blades tear grass rather than cutting cleanly, leaving your lawn susceptible to browning and disease. Doing this frequently increases the risk. Sharpen blades regularly for a healthy cut.
2. Smart Watering Habits
- Deep and Infrequent: Aim for deep watering once or twice a week. This approach incentivizes the root zone to dig deep, creating a resilient lawn that withstands drought.
- Early Morning Watering: Watering between 5–9 AM reduces evaporation and allows grass blades to dry, significantly lowering the risk of fungal diseases. St. Augustine grass has earned the humorous nickname “St. Fungustine” due to its tendency to develop fungal issues when overwatered, especially at night. Keeping a proper watering schedule is key to preventing these problems and maintaining a healthy lawn
3. Fertilizing for Maximum Health
- Balanced Nutrients: For optimal lawn health, choose a slow-release fertilizer formulated for southern grasses, ensuring the right balance of nitrogen, phosphorus, and potassium. A well-rounded, balanced fertilizer is a safe bet, delivering steady nutrients over time. Be mindful of cheap synthetic fertilizers, as they often contain high levels of salts, which can build up in the soil over time and negatively impact its health. For best results, feed your lawn every 6 to 10 weeks throughout the growing season.
- Timing is Key: Fertilize in early spring, early summer, and early fall to maintain consistent, healthy growth throughout the season. For even better color and resilience, consider spoon-feeding—applying smaller, more frequent doses of fertilizer rather than larger, infrequent applications. This method ensures a steady nutrient supply, reducing stress on the grass and promoting a lusher, more even lawn. It’s a technique used by turf professionals and lawn care enthusiasts who want the best possible results. Stay tuned—we’ll be diving deeper into the benefits and best practices of spoon-feeding in an upcoming post!
4. Effective Weed Control
- Preventive Measures: Applying pre-emergent herbicides in early spring and late fall is one of the most effective ways to prevent weeds before they take root. These treatments create a barrier that stops weed seeds from germinating, drastically reducing weed invasions throughout the season. Consistent applications at the right times of year will keep your lawn healthier and minimize the need for excessive weeding.
- Natural Density: We’re all about promoting natural and organic lawn care whenever possible. The best defense against weeds starts with a healthy, well-fed lawn. By maintaining a proper feeding schedule and encouraging thick, lush growth, your grass will naturally outcompete weeds by blocking sunlight and limiting access to nutrients. A dense lawn acts as a living barrier, reducing the need for chemical weed control while keeping your yard looking its best.
5. Managing Common Pests and Diseases
- Monitor Regularly: Regularly inspect your lawn for common threats like chinch bugs, grub worms, and fungal infections, especially during the warmer months when they thrive. Chinch bugs and Take-All Root Rot are notorious for damaging St. Augustine grass, often leading to widespread die-off if left unchecked. The best defense is a proactive approach—spotting early signs and taking swift action can save your lawn from costly damage. Stay ahead of the game with routine monitoring and preventative treatments.
- Act Promptly: Opt for environmentally friendly treatments to manage pests and diseases while keeping your lawn and soil healthy. If an infestation becomes severe, consider seeking professional lawn care assistance to ensure the issue is properly diagnosed and treated before it causes significant damage.
