About Lawn Care in Jim Wells County, Texas
Intense heat lowers Jim Wells lawn scores
A lawn difficulty score of 23.1 makes this one of the tougher Texas counties for turf management. It sits well below the state average of 31.7, primarily due to the 144 days of extreme heat in zone 9b.
High thermal demand for southern turf
The county records 8,377 growing degree days, indicating a very long and fast-growing season for grass. With just 27.9 inches of annual rain, you must supplement nearly 22 inches of water to reach the ideal lawn requirement.
Sandy, alkaline soil challenges nutrient levels
The soil is comprised of 57.0% sand and has a pH of 7.15, which is slightly above the ideal 7.0 limit. This alkalinity can sometimes lock out iron, so look for fertilizers specifically designed for southern, sandy soils.
A full year of severe drought conditions
Every acre of the county is currently in severe drought, and this has lasted for 53 consecutive weeks. Strict water conservation, such as using smart irrigation controllers, is necessary to keep lawns alive without wasting resources.
Start your season in late January
With the last frost occurring around January 31, Jim Wells County has an exceptionally long growing window. Warm-season grasses like Bermuda or Zoysia are the most resilient choices for this zone 9b climate.
