Data Story
About Lawn Care in Park County, Colorado
High-Altitude Turf Hurdles
Park County presents a tough environment with a lawn difficulty score of 30.5. In this high-elevation Zone 5b region, homeowners face more maintenance obstacles than the state average of 37.4.
Short Seasons and No Heat
The climate features zero days of extreme heat and a very short growing window of just 797 degree days. With only 13.9 inches of rain, irrigation is vital even without the threat of high temperatures.
Overcoming Poor Soil Data
Local soil data is limited, but high-elevation geography often results in rocky or acidic conditions. Amending your soil with organic matter will help provide the nutrients needed during the very brief growing season.
Severe Drought Risks
Severe drought conditions currently affect 67.6% of the county after a 50-week drought period over the last year. Use drought-resistant seed and focus on maintaining soil moisture during the dry summer months.
The Short Window for Growth
Stick with the hardiest cool-season grasses like Fine Fescue to survive the extremely short window between frosts. With the last spring frost on June 16 and the first fall frost on September 9, timing is critical for success.
