About Lawn Care in Jones County, South Dakota
Overcoming Hardship in Jones County
Jones County has a lawn difficulty score of 45.6, indicating it is tougher to maintain a lawn here than in the average American county. Residents in this Zone 5a area must contend with high clay content and lower-than-average precipitation.
Thriving in 34 Days of Heat
Lawns endure 34 days of extreme heat annually, significantly higher than the state average of 24. With only 21.6 inches of rain, the 2,917 growing degree days often lead to rapid soil drying and turf stress.
Managing Heavy Clay Soils
With a high clay content of 39.2%, soil compaction is a major concern that requires regular aeration. The pH of 7.33 is slightly alkaline, so adding sulfur or organic matter can help bring it closer to the ideal 6.0-7.0 range.
Coping with Prolonged Dry Spells
Jones County recorded 28 weeks of drought in the past year, with 70.9% of the land still abnormally dry. To combat this, set mower blades higher to shade the soil and reduce water evaporation from the lawn surface.
Establish Your Lawn Early
Drought-tolerant Tall Fescue is recommended to handle the high clay and heat. Seed in early May after the frost on the 3rd, or during the cool period in September before the October 9th fall frost.
