About Lawn Care in Benton County, Missouri
Benton County Lawns Meet the Mark
Benton County's lawn difficulty score of 65.5 is slightly better than the Missouri average, making it a solid place for home landscaping. In hardiness zone 6b, the county enjoys a balance of northern and southern climate traits.
Long Seasons and High Degrees
The county sees 4059 growing degree days, resulting in a long and productive growing season. With 43.0 inches of rain and 38 extreme heat days, the climate is slightly more aggressive than the state average but remains manageable for most homeowners.
Addressing Soil Acidity
The local soil pH is 5.88, which is just below the preferred range for most turfgrasses. With a balanced mix of 20.1% clay and 19.8% sand, focusing on pH correction with lime will be more important than changing the soil's physical texture.
Resilience in the Face of Dryness
Benton County experienced 17 weeks of drought over the past year and remains 100% abnormally dry today. Because the county has a long history of dry spells, selecting grass with high drought tolerance is a smart long-term investment.
Planting for a Long Season
Your first fall frost doesn't typically arrive until October 30th, giving you a very long window for growth. Seed your lawn after the April 13th frost, and choose a blend that can withstand the 38 annual days of extreme heat.
