About Lawn Care in Edwards County, Illinois
Edwards County's Lawn Challenge
With a difficulty score of 52.1, Edwards County is one of the toughest places in Illinois to maintain a lawn. While still easier than the national median, it is significantly more demanding than the state average of 69.8.
High Heat and Heavy Rain
Lawns here must endure 45 extreme heat days annually—nearly double the state average—and 50 inches of precipitation. This combination of intense heat and moisture can create high humidity and disease pressure for cool-season grasses.
Slightly Acidic Soil Baseline
The soil pH of 6.13 is on the lower end of the ideal range, meaning some lawns may eventually benefit from a lime application. The soil consists of 20.6% clay and 11.4% sand, making it relatively heavy and prone to holding onto moisture.
Monitoring Drought Pockets
While 100% of the area is abnormally dry, only 14.6% is in severe drought currently. Having spent 27 weeks in drought over the last year, local lawns require deep-root watering to withstand the high 78.4°F July average temperatures.
Heat-Tolerant Turf Required
In Hardiness Zone 6b, heat-tolerant species like Turf-Type Tall Fescue or Zoysia are your best bets. Take advantage of the long growing season by seeding after the early April 7 frost but before late October.
