Data Story
About Lawn Care in Edmonson County, Kentucky
Lawn care is a challenge in Edmonson
Edmonson County has a difficulty score of 52.9, making it much tougher to manage than the state average of 66.3. The combination of intense summer heat and high rainfall creates a demanding environment for turf.
Extreme heat days stress your grass
With 44 days of heat at or above 90°F, local lawns face significantly more stress than the state average of 30 days. This heat, combined with 53.5 inches of rain, often leads to high humidity and increased disease pressure.
Focus on drainage and local testing
While specific soil pH and texture data are not available, the high rainfall suggests a need for well-draining soil structures. A professional soil test can help determine if the heavy rains have leached vital nutrients from your yard.
Heat waves pose a bigger threat than drought
The county is currently drought-free, though it did experience seven weeks of drought over the last year. In this climate, protecting your lawn from the 44 extreme heat days is usually more critical than managing rainfall shortages.
Prioritize heat-tolerant grass varieties
With a frost-free window from April 9 to October 30, you have a long season to work with. Choose heat-tolerant tall fescues that can survive the intense 90°F summers typical of this region.

- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft

- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
