As the Texas spring unfurls warmer temperatures, homeowners across the Lone Star State face the annual task of preparing their lawns for the coming heat. Texas's climate, with its stark regional variations from the humid Gulf Coast to the arid West Texas plains, demands a thoughtful approach to spring lawn care.
We’ve developed this guide to offer you essential tips tailored to Texas's unique soil types, prevalent pests and typical weather patterns. It will ensure that your lawn not only survives but thrives in this diverse environment.
Spring Lawn Care Tips for Texas Homeowners
Texas Soil Testing & Adjustment
Soil types in Texas lawns vary widely, with sandy soils prevalent along the coast and dense clay soils common in other regions. In the spring, homeowners are advised to conduct a soil test to assess pH levels and nutrient content. Conducting a soil test is crucial for maintaining a healthy lawn, as an unbalanced pH level can prevent the lawn from absorbing essential nutrients.
Texas soils are frequently found to be lacking in nitrogen and phosphorus. However, some areas in the state don’t need phosphorus at all. Based on the results of your soil test, consider making adjustments by incorporating organic compost to enhance the soil's structure and nutrient profile, particularly in areas with heavy clay.
Fertilizing Texas Lawns
Begin fertilizing your lawn once the grass starts actively growing, typically when soil temperatures consistently stay around 65°F, usually in late spring in Texas. It's best to wait until the lawn has been mowed twice before applying fertilizer to ensure the grass is actively growing.
Applying fertilizer too early might cause setbacks if unexpected frost occurs. Frost dates in Texas vary by location:
- Dallas: typically around March 1–10
- Deer Park: typically around February 1–10
- Del Rio: typically around February 21–29
- Denison: typically around March 21–31
- Fort Worth: typically around March 12
- San Antonio: typically around February 23
Select a high-quality, slow-release fertilizer that suits the specific needs highlighted by your soil test results.
In Texas, warm season grasses like bermuda, St. Augustine, and zoysia especially benefit from fertilization in early spring as they emerge from dormancy. Spread the fertilizer evenly over your lawn, adhering to recommended rates to prevent over-fertilization, which can cause nutrient runoff and environmental pollution.
We suggest the Lawnifi Spring Fertilizer Box as the best lawn fertilizer for spring lawn care, which provides tailored nutrition to help your grass recover from winter and thrive in spring. Each application covers 5,000 sq. ft. and is designed for easy use with a hose-end sprayer.
Weed Control Strategies for Texas Lawns
Preventive Care:
Apply a pre-emergent herbicide for spring lawn care when soil temperatures consistently reach about 55 degrees Fahrenheit—usually between February and March in Texas—to stop weed seeds from germinating. Learn more here.
Active Management:
Use post-emergent herbicides to tackle visible weeds like dandelions and crabgrass. Ensure selective herbicide use, as non-selectives will kill any and all vegetation it comes into contact with
Apply post-emergent weed control throughout the spring as needed to control summer annual and perennial broadleaf weeds like:
- Crabgrass
- Goosegrass
- Sandspur
- Dallisgrass
- Dandelion
- Chickweed
- White Clover
- Knotweed
- Spurge
- Dollarweed
- Doveweed
- Lespedeza
Post-emergent products containing multiple broadleaf active ingredients, like SpeedZone Broadleaf Herbicide for Turf, are the best spring lawn treatments because they’re more effective in controlling broadleaf weeds.
If you start to notice grassy weeds such as crabgrass or goosegrass, Recognition is great for St. Augustine and zoysia lawns. MSMA post-emergents are best for bermuda grass lawns. Be sure to follow product labels for any control product appropriately during application.
If you notice weeds and aren’t sure which type they are, check out our Identifying Common Lawn Weeds blog.
Note: St. Augustine and centipede lawns are sensitive to active ingredients like 2,4-D, MSMA, or Mecroprop. To control weeds, apply an Atrazine-based weed control product like Hi-Yield Atrazine. Atrazine products serve as both pre- and post-emergent herbicides.
Pest Management in Texas Lawns
Certain pests often start to become active in spring. Properly identifying these pests is crucial for determining the most effective treatment method.
In Texas lawns, common nuisances include grub worms and chinch bugs, both of which can significantly damage grass.
For active grub worm infestations, products like Dylox 6.2 are effective, while Imidacloprid-based products like Imidacloprid 0.5 G can prevent early-season outbreaks. Bifen L/P is suitable for treating chinch bug issues.
For more detailed information, refer to our Insect Identification blog and always follow label instructions carefully.
Managing Spring Lawn Diseases in Texas
Texas lawns are susceptible to fungal diseases like brown patch and large patch, particularly during the cool, moist conditions of spring.
To combat these diseases, it's essential to maintain balanced moisture levels through proper watering and aeration during spring lawn care. Fungicides should be used as a last resort and applied strictly according to the manufacturer's guidelines.
As your warm season grass emerges from winter dormancy, watch for signs such as circular brown or yellow patches, which could signal spring dead spot, large patch, or gray leaf spot diseases.
For proactive disease management, consider using a systemic disease control product like Prostar for treating diseases in zoysia and St. Augustine grasses, and Heritage G or Propiconazole for issues in bermuda grass, especially as a preventative measure if you've encountered similar problems in past seasons. Rotate these fungicides to manage disease resistance effectively.
Apply fungicide treatments before starting spring fertilization, since the nitrogen in fertilizers can encourage fungal growth. Delay fertilization for a few weeks after applying the disease control product to help prevent disease spread.
Always read and follow product labels carefully.
Spring Lawn Care Watering Practices for Texas Lawns
As spring arrives, it’s best to conduct an irrigation audit to make sure water is being delivered in appropriate amounts to different areas of your lawn.
Maintaining sprinklers is key. Lawns typically need 1 inch of water per week unless adjusted for weather conditions. Overwatering can lead to shallow roots and lawn problems, while deep, infrequent watering promotes healthier, resilient roots.
Efficient watering, particularly early in the morning, reduces evaporation and minimizes disease risks.
Mowing and Maintenance Specific to Texas
Before your first mow of the season, make sure your mower blades are cleaned, sharpened, and maintained.
- Bermuda: Start the season with a "buzz-cut" to remove dormant grass leaves and promote new growth. Lower your mower setting, use a rotary mower with a sharpened blade, and bag all clippings to prevent clumping or disease. After this initial mowing, maintain Bermuda grass at a height of 0.5–1.5 inches.
- St. Augustine: Maintain your lawn at a height of 2–4 inches using a rotary mower with a sharpened blade. To ensure grass health and vitality, never remove more than one-third of the leaf blade during a single mowing session.
- Zoysia: For mature, established lawns, give your Zoysia a "buzz-cut" at the start of spring to encourage vigorous growth. Use a sharpened blade on your rotary mower and bag all clippings. After the initial mowing, adjust the height setting based on your grass type: fine-bladed Zoysia should be kept between 0.5–1.5 inches, while coarse-bladed Zoysia is best maintained at 1–2 inches. After the "buzz-cut," you can resume spreading clippings on the lawn as mulch.
Sharp blades are vital for making clean cuts, which reduce stress on the grass and decrease the risk of disease. Additionally, to maintain grass health, adhere to the one-third rule, avoiding removing more than one-third of the grass blade in a single mowing.
Aeration
Aeration is key to alleviating soil compaction and boosting water and nutrient uptake, making early spring an optimal time for this practice in Texas as the grass begins its active growth.
Why Aerate?
Aeration enhances root breathing and nutrient absorption by breaking up compacted soil.
Best Practices:
The timing of aeration should align with your lawn’s peak growth period. Warm season grasses, typical in Texas, benefit most from aeration in late spring.
Filling in Bare Spots
Spring is an ideal time to address bare spots or thin areas in your lawn by overseeing or using grass plugs. For best integration, select a grass seed variety that matches your existing turf.
