Data Story
About Lawn Care in Prowers County, Colorado
Balancing Heat and Hardiness in Prowers
Prowers County scores a 43.1 on the lawn difficulty scale, making it one of the more hospitable regions in Colorado for turf grass. Its location in Zone 6a allows for a wider variety of grass types compared to the colder mountain counties.
Navigating Intense Summer Heat
The climate is defined by 76 extreme heat days annually—nearly triple the state average—and a high 3706 growing degree days. With just 15.6 inches of rain, lawns here require heavy irrigation to survive the scorching July average of 78.4°F.
Working with Alkaline Clay Loam
The soil is a clay loam with 20.5% clay and a high pH of 7.73, which can limit nutrient availability. Because the ground is classified as poorly drained, homeowners must be careful to avoid overwatering and soil compaction.
Taking Advantage of Recent Moisture
Current conditions are favorable, with 0% of the county in severe drought and only 12 weeks of drought over the past year. Maintaining a high mowing height will help shade the soil and preserve this current moisture during the hot summer months.
Seize the Long Growing Season
The long frost-free window from May 1 to October 10 is ideal for establishing resilient Buffalo grass or Tall Fescue. Use this generous season to focus on deep rooting, which is vital for surviving the 76 days of 90-degree heat.
