About Lawn Care in Andrew County, Missouri
Andrew County Boasts Excellent Lawn Conditions
With a lawn difficulty score of 75.0, Andrew County is one of the easier places in Missouri to maintain a lush green space. This score far exceeds the national median of 50.0 and the state average of 63.7, signaling a very hospitable environment for zone 6a turf.
Consistent Growing Conditions
The county receives 36.8 inches of annual precipitation, providing enough moisture to support steady growth without the excessive rot risks of wetter regions. While specific growing degree day data is limited, the 29 extreme heat days suggest a more temperate summer than many Missouri neighbors.
Well-Drained Silty Clay Loam
Andrew County features well-drained silty clay loam with a solid 28.0% clay content. The soil pH of 6.37 is well within the ideal range, meaning grass can easily access the nitrogen and phosphorus needed for a deep green color.
Short-Term Drought Resilience
The county only experienced 13 weeks of drought over the past year, making it much more resilient than many other parts of the state. Current conditions show 77.7% of the area is abnormally dry, so maintaining a 3-inch mowing height will help shade the soil and retain moisture.
Planting for Success in Andrew
Tall Fescue is the champion for this well-drained soil and temperate climate. Aim to establish new sod or seed in early spring to take advantage of the gentle transition into the 76.9°F average July temperatures.
