About Lawn Care in Newton County, Texas

Navigating High-Water Lawn Care

Newton County has a lawn difficulty score of 26.1, which is significantly more challenging than both state and national averages. Homeowners in this Zone 9a region deal with intense moisture and heat.

Excessive Rain and Rapid Growth

With 56.2 inches of annual rainfall, Newton is one of the wettest counties in Texas. This abundance, combined with 93 heat days and 6,290 growing degree days, leads to explosive grass growth and potential drainage issues.

Managing Soils in High-Rain Areas

Specific soil data is limited for Newton County, but high rainfall typically leads to nutrient leaching. Frequent soil testing is recommended to monitor nutrient levels and ensure your lawn isn't becoming too acidic.

Sudden Drought in a Wet Climate

Despite the 56.2 inches of annual rain, 73.8% of the county is currently in severe drought. After 20 weeks of drought this past year, even these wet-climate lawns need a backup irrigation plan for dry spells.

Resilient Options for Southeast Texas

St. Augustine grass is the standard for Zone 9a, as it handles the heat and heavy rainfall well. Wait until after March 9 to plant, ensuring the soil is warm enough for new roots to take hold.

Seasonal Lawn Care Checklist

Spring

  • Apply pre-emergent herbicide when soil reaches 55F
  • 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

Fall

  • Overseed warm-season lawns if thinning
  • Apply fall fertilizer (highest N application for cool-season)
  • Continue mowing until growth stops
  • Rake or mulch leaves to prevent smothering

Winter

  • Apply pre-emergent for winter weeds
  • Service mower and sharpen blades
  • Plan spring soil amendments based on fall test
  • Overseed with ryegrass for winter color
