Texas Bermuda Grass Seasonal Care & Planting Calendar

Understanding Texas Climate Zones for Bermuda Grass

Texas spans multiple USDA hardiness zones (7a through 9b), meaning a Texas A&M Turfgrass maintenance schedule that works in the Panhandle will fail on the Gulf Coast. Bermuda grass (Cynodon dactylon) is a warm-season perennial that thrives in heat but requires precise seasonal timing to survive Texas winters and outcompete weeds. The fundamental rule of Bermuda care is to base your calendar on soil temperature, not the calendar date. Soil temperatures at a 2-inch depth dictate pre-emergent timing, green-up, and winter dormancy.

Regional Dormancy Windows:
• Panhandle/High Plains (Zones 7a-7b): 150-180 active growing days. Dormancy typically lasts from late October through early April.
• North/Central Texas (Zones 8a-8b): 200-220 active growing days. Dormancy runs from November to mid-March.
• South Texas/Gulf Coast (Zones 9a-9b): 250-280 active growing days. Brief or intermittent dormancy from December to February.

Spring Awakening: Green-Up and Establishment

Spring in Texas is defined by the transition from dormancy to active growth. The most common mistake homeowners make is applying nitrogen fertilizer too early, which feeds winter weeds and forces premature, vulnerable growth.

Pre-Emergent and Weed Control

Apply a pre-emergent herbicide like Prodiamine 65 WDG at a rate of 1.15 oz per 1,000 sq ft when soil temperatures hit 53°F to 55°F for three consecutive mornings. In Central Texas, this usually occurs in late February; in the Panhandle, expect this in mid-March. Avoid 'weed and feed' combination products during green-up, as the nitrogen will disrupt the Bermuda's natural root-building phase.

Planting and Establishment

If you are establishing a new lawn or repairing bare spots, timing is critical. Bermuda seed requires warm soil to germinate, while sod needs warmth to knit roots before summer stress.

Once the lawn is 50% green, apply a starter fertilizer high in phosphorus (such as a 10-18-10 blend) at 1 lb of nitrogen per 1,000 sq ft to support rhizome expansion. Mow hybrid Bermuda down to 1 inch and common Bermuda to 1.5 inches to encourage lateral spread rather than vertical growth.

Summer Peak: Heat, Drought, and Heavy Traffic

From June through August, Texas Bermuda grass enters its peak metabolic phase. The goal shifts from establishment to stress management, specifically mitigating drought and soil compaction.

Precision Irrigation and Evapotranspiration

The standard advice of 'water an inch a week' is flawed because it ignores Evapotranspiration (ET) rates. In July, Dallas-Fort Worth experiences ET rates of up to 0.25 inches per day, requiring 1.5 to 1.75 inches of water weekly. Conversely, Houston's higher humidity lowers ET rates, meaning 1 inch per week is sufficient. Water deeply and infrequently—apply 0.5 inches twice a week rather than light daily sprinklings. This forces roots to grow 6 to 8 inches deep, accessing cooler soil moisture.

Summer Fertilization and Iron Chlorosis

Apply a slow-release nitrogen fertilizer (like a 15-5-10 or 16-4-8 blend) every 6 to 8 weeks. As of 2026, premium 50lb bags of professional-grade turf fertilizer average $55 to $75. Central and West Texas soils are notoriously alkaline (pH 7.5+), which locks up iron and causes Bermuda grass to turn yellow (chlorosis) despite adequate nitrogen. If you see yellowing between leaf veins, apply a liquid chelated iron product (Fe-EDDHA) at 3 oz per 1,000 sq ft. Avoid granular iron sulfate in alkaline soils, as it will quickly oxidize and become unavailable to the plant.

Fall Transition: Preparing for Winter Dormancy

Fall care in Texas dictates how well your Bermuda grass survives the winter and how quickly it greens up the following spring. The primary objective is to halt top growth and fortify the root system.

The Potassium Shift

By August 15th in the Panhandle and September 1st in Central/South Texas, you must stop applying high-nitrogen fertilizers. Late-season nitrogen forces tender, succulent growth that will be destroyed by the first freeze, leading to severe winterkill. Instead, apply a winterizer fertilizer high in potassium, such as Sulfate of Potash (0-0-50) at a rate of 1 to 1.5 lbs per 1,000 sq ft. Potassium acts as an antifreeze within the plant cells, lowering the freezing point of the cellular fluid and increasing cold tolerance.

Overseeding Decisions

Many Texans overseed their dormant Bermuda with ryegrass for winter color. However, Texas A&M AgriLife Extension turfgrass specialists strongly advise against overseeding with Perennial Ryegrass in the Panhandle and North Texas. Perennial ryegrass survives into late spring and aggressively competes with Bermuda during its critical green-up phase, often causing permanent thinning. If winter color is mandatory, use Annual Ryegrass at 10-15 lbs per 1,000 sq ft in October, as it naturally dies off when summer heat returns.

Winter Rest: Dormancy and Weed Control

During December through February, the Bermuda grass is completely dormant, but winter annual weeds like Poa annua (annual bluegrass) and henbit are actively growing.

• Post-Emergent Herbicides: Apply a three-way herbicide containing 2,4-D, Dicamba, and Mecoprop (MCPP) on days when air temperatures are above 50°F and no rain is expected for 48 hours. This will kill broadleaf weeds without harming the dormant Bermuda rhizomes.
• Traffic Control: Dormant Bermuda grass crowns are highly susceptible to physical damage. Limit heavy foot traffic and avoid parking vehicles on the dormant turf, as crushed crowns will result in dead, muddy patches that persist well into May.
• Disease Mapping: Walk the lawn in late winter to identify circular, sunken areas. These are likely Spring Dead Spot (SDS), a devastating fungal disease. Map these coordinates to apply targeted preventative fungicides (like Velista or Headway) exactly when soil temperatures reach 50°F the following fall.

Frequently Asked Questions

Can I plant Texas Bermuda grass from seed in the Panhandle?

Yes, but the window is narrow. You must wait until the soil temperature consistently exceeds 65°F, which usually doesn't happen until late May or early June in the Panhandle. This leaves only about 100 days for the seedlings to establish deep rhizomes before the first fall frost. For higher success rates in Zone 7, opt for cold-tolerant hybrid sod varieties like 'MidIron' or 'TifTuf' instead of seed.

Why is my Bermuda grass turning purple in the fall?

Purpling is a natural physiological response to cold stress and the cessation of chlorophyll production as the plant prepares for dormancy. It is not a disease or a nutrient deficiency. However, if the purpling is accompanied by stunted growth and occurs in the middle of summer, it indicates a severe phosphorus deficiency or soil compaction preventing root uptake.

How do I level a bumpy Bermuda lawn in Texas?

The best time to top-dress and level a Bermuda lawn is during peak summer growth (June or July). Apply a mix of 70% washed river sand and 30% compost at a depth of no more than 0.25 inches per application. The aggressive summer growth rate of Bermuda grass will push through the sand layer within 7 to 10 days, allowing you to repeat the process every three weeks until the lawn is perfectly graded.
