About Lawn Care in Polk County, Texas
Abundant water but high heat stress
Polk County holds a difficulty score of 24.8, placing it below the Texas state average of 31.7. While rainfall is plentiful in this Zone 9a region, the extreme heat and humidity create their own set of maintenance hurdles. Success here depends on managing moisture as much as providing it.
Heavy rainfall fuels rapid growth
Annual precipitation averages a generous 53.9 inches, which is significantly higher than the state average of 31.9. This moisture, combined with 7,096 growing degree days, means the mowing season is long and intensive. The first frost doesn't typically arrive until November 24, allowing for an extended growing period.
Managing local soil variations
Specific soil data is limited for this area, but regional trends suggest acidic conditions common in East Texas piney woods. Without local soil metrics, homeowners should conduct a private test to check for drainage and pH balance. Ensuring good drainage is vital to prevent root rot during the heavy rainy season.
Severe drought despite high rainfall
Despite high annual averages, 100% of the county is currently facing severe drought conditions. The county has recorded 23 weeks of drought in the past year, highlighting the feast-or-famine nature of local weather. Rain barrels and smart irrigation controllers help manage these unpredictable dry spells.
Thriving in the humid heat
St. Augustinegrass and Zoysia are top performers in Zone 9a, as they handle both the moisture and the heat well. Planting should occur in early March to allow roots to establish before the 103 days of extreme heat begin. Your lawn will grow aggressively, so prepare for a busy summer maintenance schedule.

- Begin mowing when grass reaches 3 inches
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Raise mowing height to reduce heat stress
- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
