Quick Answer: Spring lawn care in Texas begins in late February with pre-emergent herbicide application, followed by first mowing in March as warm-season grasses like Bermudagrass and St. Augustinegrass emerge from dormancy. The key is timing your fertilization for April when soil temperatures consistently reach 65°F across zones 6b-9a.
Key Takeaways
- Apply pre-emergent herbicide in late February to early March before soil temperatures reach 55°F
- Begin mowing in March when grass starts actively growing
- Start fertilizing in April when soil temperatures consistently stay above 65°F
- Focus on warm-season grasses: Bermudagrass, St. Augustinegrass, Zoysiagrass, and Buffalograss
- Monitor for early spring pests like chinch bugs and prevent crabgrass emergence
Spring marks the transition from dormancy to active growth for Texas's warm-season grasses. With the state's diverse climate spanning from humid East Texas to arid West Texas across USDA zones 6b-9a, timing your spring lawn care correctly sets the foundation for a healthy, resilient lawn through the challenging summer months ahead.

When Should I Apply Pre-Emergent Herbicide in Texas?
Pre-emergent herbicide application is your first critical spring task in Texas. Apply pre-emergent herbicide between late February and early March, before soil temperatures consistently reach 55°F[1]. This timing prevents crabgrass, dallisgrass, and other summer weeds from germinating as temperatures warm.
Monitor soil temperature using a soil thermometer at 2-inch depth for three consecutive days. In North Texas (zones 6b-7a), aim for late February application, while South Texas (zones 8b-9a) should apply in mid-February[2]. Don't wait too long – once weeds germinate, pre-emergent becomes ineffective.
Choose a pre-emergent containing pendimethalin or prodiamine for best results against Texas weeds. Water lightly after application to activate the herbicide barrier, but avoid heavy irrigation that can wash away the treatment.
How Do I Care for Different Texas Grass Types in Spring?
Texas homeowners primarily maintain four warm-season grass types, each requiring specific spring care approaches.
Bermudagrass Care
Bermudagrass dominates Texas lawns due to its heat and drought tolerance. Begin mowing when new growth appears in March, cutting at 1-2 inches height[3]. Bermudagrass responds excellently to spring fertilization starting in April with a nitrogen-rich fertilizer.
Watch for Bermuda mites, which cause yellowing and stunted growth as grass emerges from dormancy. Apply appropriate miticide if damage appears.
St. Augustinegrass Maintenance
St. Augustinegrass thrives in East Texas's humid conditions but requires careful spring management. Mow at 3-4 inches to maintain density and shade out weeds[1]. This grass type is susceptible to brown patch disease in spring's cool, wet conditions.
Avoid over-fertilizing St. Augustine in early spring, as excess nitrogen promotes disease development. Wait until April for fertilization and ensure proper drainage to prevent fungal issues.
Zoysiagrass and Buffalograss
Zoysiagrass emerges later than other warm-season grasses, often not until late March or April. Be patient and avoid overwatering dormant Zoysia, which can promote disease. Buffalograss, native to Texas, requires minimal spring intervention but benefits from light fertilization in late April[4].
What Spring Fertilization Schedule Should Texas Homeowners Follow?
Proper fertilization timing separates successful Texas lawns from struggling ones. The Texas A&M AgriLife Extension recommends beginning fertilization in April when soil temperatures consistently exceed 65°F[1].
Apply 1 pound of nitrogen per 1,000 square feet for your first spring feeding. Use a slow-release fertilizer to provide consistent nutrition without promoting excessive growth that attracts pests. Avoid fertilizing dormant grass, as nutrients wash away without plant uptake.
For North Texas, schedule fertilization in mid-April, while South Texas can begin in early April. Monitor weather patterns – avoid fertilizing before heavy rain events that can cause nutrient runoff.
Consider soil testing every 2-3 years to determine specific nutrient needs. Texas soils often lack adequate phosphorus and may have pH imbalances affecting nutrient availability[5].
How Do I Prevent Common Texas Spring Lawn Problems?
Texas lawns face unique spring challenges requiring proactive management strategies.
Pest Prevention
Chinch bugs emerge as temperatures warm, particularly in St. Augustinegrass. Monitor for yellowing patches and apply appropriate insecticide if populations exceed treatment thresholds. White grubs, overwintering in soil, can damage grass roots as they become active[6].
Fire ants remain active year-round in Texas but increase activity in spring. Apply targeted treatments to mounds rather than broadcast applications for environmental responsibility.
Disease Management
Brown patch fungus thrives in Texas's spring conditions with cool nights and warm, humid days. Improve air circulation by pruning nearby shrubs and avoid evening watering that leaves grass wet overnight. Take-all root rot, common in alkaline Texas soils, requires proper pH management and adequate drainage[1].
Weed Control
Beyond pre-emergent application, monitor for winter weeds like henbit that germinate in fall but become visible in spring. Hand-pull small populations or use selective post-emergent herbicides for larger infestations.
Nutsedge, a persistent Texas weed, requires specific herbicides containing halosulfuron or sulfentrazone. Don't confuse nutsedge with grass – it has triangular stems and grows faster than surrounding turf.
Spring lawn care in Texas sets the stage for year-round lawn health. Start with proper pre-emergent timing, follow appropriate fertilization schedules for your grass type, and monitor for region-specific pests and diseases. Remember that Texas's diverse climate means adjusting timing based on your specific zone. Focus on building strong root systems in spring to help your lawn survive the intense summer heat ahead.
Take action now by checking soil temperature for pre-emergent application timing and preparing your mower for the upcoming growing season. Your lawn will reward proper spring care with robust growth and better stress tolerance throughout the year.
