About Lawn Care in Laclede County, Missouri
Managing Turf in Laclede
Laclede County has a lawn difficulty score of 57.1, which is lower than the Missouri average but still better than the national median. This 6b hardiness zone requires active management to maintain a lush appearance.
Ample Water for Hot Summers
Lawns receive a generous 45.9 inches of annual precipitation, which is higher than the state average. This extra water is vital during the 38 days of extreme heat the county typically experiences each year.
Correcting Acidity and Sandy Mixes
The soil pH is 5.90, which is slightly below the ideal 6.0-7.0 range and may require lime treatments. A sand content of 21.0% helps with texture, but the subaqueous drainage indicates local areas may struggle with water management.
Adapting to Abnormally Dry Conditions
After 28 weeks of drought last year, 100% of the county remains abnormally dry today. Using taller mowing heights can help shade the soil and preserve the moisture from the county's high annual rainfall.
Ready for Spring in Zone 6b
Tall Fescue and Zoysia are excellent choices for the variable 6b climate. Start your planting projects after the final spring frost on April 17th to give your grass time to establish before the summer heat.
