Data Story
About Lawn Care in Goliad County, Texas
Warm and Sandy Coastal Plains
Goliad County earns a lawn difficulty score of 32.8, placing it slightly above the Texas state average of 31.7. This Zone 9a region offers a long growing season but requires significant heat management.
Intense Heat with Decent Rain
Residents navigate 122 extreme heat days, which is much higher than the state average of 105. While 35.2 inches of annual rain helps, the 7,577 growing degree days mean grass grows fast and needs frequent mowing.
Neutral Soils for Easy Growth
A soil pH of 7.06 is near-neutral, making it easy to manage without heavy lime or sulfur treatments. The soil is 59.1% sand, which offers good drainage but means you must monitor moisture levels closely during the summer.
Severe Drought Persistence
The entire county is currently experiencing severe drought, having dealt with these conditions for 41 weeks of the past year. Focus on soil health by avoiding heavy nitrogen fertilizers during these dry periods to reduce grass stress.
Warm-Season Turf Success
St. Augustine and Bermuda are excellent for these sandy soils and hot summers. With the last frost usually passing by February 25, you can get a head start on your lawn before the triple-digit temperatures arrive.
