Spring is here, and it’s the perfect time to give your St. Augustine lawn the tender loving care it needs to thrive during the warm months ahead. In Central Texas, where the climate brings both a burst of energy and its share of challenges, knowing how to properly care for your lawn can make all the difference. In this blog, we’ll walk you through essential steps—from cleaning up winter remnants to fine-tuning your watering and fertilization routine—to ensure your lawn is healthy, vibrant, and ready for the season.

​

1. Clean-Up and Preparation

Start Fresh:
After a cooler winter, your lawn may be littered with fallen leaves, twigs, and other debris. Start by raking the area thoroughly to remove any buildup. This not only enhances the look of your lawn but also prevents mold growth and improves air circulation.

Dethatching:
St. Augustine grass can sometimes develop a thick layer of thatch—a mix of dead grass, roots, and organic material—that inhibits water and nutrient absorption. If your lawn has more than ½ inch of thatch, consider dethatching. Use a dethatching rake or machine designed for your lawn type, being careful not to damage the healthy grass.

 

2. Mowing for Health and Aesthetics

Proper Mowing Height:
St. Augustine grass thrives when maintained at a height of 3 to 4 inches. Mowing at this height encourages a deep root system, which is crucial for drought resistance and overall lawn health. Adjust your mower blade to ensure an even cut and always use a sharp blade to reduce stress on the grass.

Regular Mowing Routine:
As the grass begins to grow more vigorously in spring, establish a regular mowing schedule. Avoid cutting more than one-third of the grass height in a single mowing session to prevent shock and maintain a lush, green appearance.

 

3. Watering Wisely in a Texas Climate

Optimal Watering Times:
Central Texas can be unforgiving when it comes to heat, so watering your lawn correctly is key. Water early in the morning to minimize evaporation and fungal growth. Aim to provide about 1 inch of water per week, adjusting based on rainfall and specific soil conditions.

Deep and Infrequent:
Rather than daily shallow watering, opt for deeper, less frequent sessions. This approach encourages deep root growth and helps your lawn better withstand the inevitable Texas heat waves.

 

4. Fertilization: Feeding Your Lawn

When to Fertilize:
Spring is a critical time for fertilizing your St. Augustine lawn. Once the grass shows signs of active growth (typically when daytime temperatures reach around 65°F), it’s time to feed your lawn.

Choosing the Right Fertilizer:
A balanced, slow-release fertilizer with a higher nitrogen content works best for St. Augustine grass. Nitrogen promotes vigorous leaf growth, which is essential for a dense, green lawn. Follow the manufacturer’s recommendations on application rates, and consider performing a soil test to determine if your lawn needs any additional nutrients.

Application Tips:

• Apply fertilizer evenly using a spreader to avoid over-fertilizing in patches.

• Water your lawn after fertilizing to help the nutrients penetrate the soil, but avoid overwatering which can wash the fertilizer away.

 

5. Pest and Weed Management

Monitoring for Pests:
St. Augustine grass is prone to chinch bugs and other pests that can damage the turf if left unchecked. Regularly inspect your lawn for signs of infestation—such as brown patches or thinning grass—and treat promptly with appropriate insecticides if needed. Natural and organic treatments are available if you prefer an eco-friendly approach.

Weed Control:
Spring is also a time when weeds begin to emerge. Consider applying a pre-emergent herbicide early in the season to prevent weeds from taking hold. If weeds have already appeared, spot-treat with a post-emergent herbicide that’s safe for St. Augustine grass, ensuring you follow label instructions to avoid damaging your lawn.

 

6. Ongoing Maintenance and Tips

Aeration:
If your soil is compacted—a common issue in Texas—consider aerating your lawn in the spring. Aeration helps water, nutrients, and oxygen reach the roots, promoting a healthier lawn.

Plugging:
In areas where your St. Augustine lawn appears thin or patchy, you might opt for plug planting. Unlike overseeding, which is not available with St. Augustine due to its growth habits, plugging helps fill in bare spots quickly.

Stay Consistent:
Regular maintenance is key. Create a seasonal care calendar and stick to it. Consistent mowing, watering, fertilizing, and pest control will ensure your lawn remains resilient against the challenges of Central Texas weather.

 

Final Thoughts

Caring for a St. Augustine lawn in Central Texas during the spring is all about preparation and consistency. By taking the time to clean, nourish, and monitor your lawn, you set the stage for a vibrant and healthy turf that can handle the heat and occasional drought of the region. Enjoy the process of nurturing your outdoor space, and watch as your lawn transforms into a beautiful, welcoming haven for family, friends, and the great Texas outdoors.

Happy Spring and happy lawn care!
