Data Story
About Lawn Care in Moultrie County, Illinois
Reliable Results in Central Illinois
Moultrie County’s lawn difficulty score of 74.4 makes it a great spot for turf enthusiasts. It comfortably exceeds the Illinois average of 69.8, providing a stable environment for Zone 6a gardening projects.
Balanced Growth Conditions
Lawns here benefit from 40.9 inches of rain, which is very close to the state average. With 22 extreme heat days, the summer stress is lower than the state benchmark of 27, allowing for more consistent green color through July.
High Clay Requires Attention
A clay content of 24.6% is among the highest in the region, meaning the soil can become easily compacted. Keep your pH in check—currently a healthy 6.50—and consider aerating every fall to keep the soil loose.
Persistent Drought Constraints
The county has spent 32 weeks in drought over the last year, and 100% of the area is currently in a severe drought (D2+) state. Watering deeply once or twice a week is far more effective than daily light mists in these conditions.
April to October Growing Window
Your planting window opens wide on April 15 after the last frost. Because of the high clay content and severe drought risk, perennial ryegrass mixed with fescue offers the best balance of fast establishment and durability.
