Data Story
About Lawn Care in Bent County, Colorado
Managing Turf in the Bent Basin
Bent County has a lawn difficulty score of 39.9, which is slightly above the state average but more difficult than the national median. Homeowners in this Zone 6a region must contend with some of the most extreme summer heat in Colorado.
Eighty-Three Days of Extreme Heat
Lawns face a massive 83 extreme heat days annually, coupled with a high 3,912 growing degree days. The low 13.4 inches of precipitation means that survival depends almost entirely on supplemental watering during the peak growing months.
Tackling Heavier Alkaline Soils
The soil pH is 7.68, meaning it is more alkaline than the ideal range and may lock out certain nutrients. The texture contains 23.3% clay, the highest in this group, which can lead to compaction if not aerated regularly.
Favorable Recent Drought Trends
While the county only saw 14 weeks of drought last year and is currently 98% drought-free, the high heat still demands water efficiency. Using smart controllers to water in the early morning can prevent evaporation during those frequent 90°F days.
Optimizing the Long Growing Season
Buffalo grass is a fantastic low-water alternative for this area's heat and soil. With a generous window between April 29th and October 15th, you have a long season to establish deep roots that can withstand the summer sun.
