Data Story
About Lawn Care in Ellis County, Texas
Ellis County Leads in Ease
With a lawn difficulty score of 46.0, Ellis County offers some of the best growing conditions in Texas. It approaches the national average of 50.0, providing a much friendlier environment than the typical Texas county.
Generous Rainfall for Texas Lawns
The county receives an impressive 40.5 inches of annual rain, placing it squarely in the ideal 30-50 inch range. While there are 102 days of extreme heat, the consistent precipitation helps maintain growth through the 6,301 growing degree days.
Heavy Clay Retention Power
The soil contains 37.2% clay, which is excellent for holding moisture and nutrients but can become compacted. The slightly alkaline pH of 7.42 may require occasional acidification to help the grass fully absorb iron and nitrogen.
Resilient Against Recent Dryness
Ellis County only faced 13 weeks of drought over the past year, the lowest in this group. While 100% of the county is currently abnormally dry, the high clay content helps the soil act as a reservoir during short rainless stretches.
Thriving in Zone 8b
Both Zoysia and Bermuda grasses perform exceptionally well here thanks to the ample rainfall and long season. The spring planting window opens wide after the last frost on March 12, allowing for early establishment.
