Data Story
About Lawn Care in Barton County, Missouri
Managing High Heat in Barton County
Barton County scores a 53.7 on the lawn difficulty scale, reflecting the challenges of gardening in zone 7a. This is nearly 10 points lower than the state average, largely due to intense summer heat and fluctuating moisture.
Forty Days of Intense Heat
The county endures 40 extreme heat days per year, which is significantly higher than the state average of 37. While the 47.3 inches of rain provides a lot of water, the 4143 growing degree days mean your mower will be working overtime during the peak season.
Sandy Foundations and Low pH
With a 27.3% sand content, Barton's soil may dry out faster than the heavy clay soils found elsewhere in Missouri. The pH of 5.91 is slightly acidic, suggesting that a light application of lime could help optimize nutrient availability for your turf.
Bracing for Dry Spells
Having spent 29 weeks in drought over the last year, this county is prone to significant water stress. Homeowners should prioritize mulch-mowing to keep clippings on the lawn, which helps retain moisture and protect the soil from the 40 days of 90°F+ heat.
Choose Heat-Tolerant Varieties
With a long growing season and an early last frost of April 9th, heat-tolerant Zoysia is an excellent choice for this climate. Ensure you establish your lawn early to survive the July average of 78.1°F, which can be brutal on younger grass.
