Data Story
About Lawn Care in Tazewell County, Illinois
Tazewell Lawns Outperform State Averages
With a lawn difficulty score of 75.4, Tazewell County is one of the more favorable places in Illinois for residential turf. This score far exceeds the national average of 50.0 and sits comfortably above the Illinois average of 69.8.
Reliable Rainfall for Central Illinois
Annual precipitation of 38.8 inches provides a steady foundation for growth, though limited local temperature data suggests monitoring local forecasts for heat spikes. The climate supports a vigorous growing season typical of Hardiness Zone 6a.
Sandy Texture Improves Natural Drainage
The soil features a 24.9% sand content, which is higher than many neighboring counties and helps prevent waterlogging during heavy rains. A pH of 6.44 is near perfect for grass, though 19.7% clay still requires occasional aeration.
Battling Severe Drought Conditions
Despite the high ease-of-growth score, 100% of the county is currently under severe drought (D2+) conditions. Residents should prioritize water conservation by letting lawns go dormant or watering strictly in the early morning hours.
Optimal Grass Types for Zone 6a
Tall Fescue is a durable choice for this region because it handles the current severe drought better than shallower-rooted varieties. While specific frost dates are missing, local growers generally find success seeding in late August or early April.
