Data Story
About Lawn Care in Brule County, South Dakota
High Difficulty for Brule Lawns
Brule County presents a challenge with a low 40.8 lawn score, well below the state average of 51.1. Homeowners in this Zone 5a area must navigate significant environmental stressors to keep their grass alive.
Scorching Summers Test Turf
Lawns endure 34 extreme heat days per year, which is 10 days more than the state average. This high heat, combined with 2,940 growing degree days, puts immense pressure on moisture levels and grass health.
Limited Local Soil Data
Comprehensive soil data for pH and texture is currently unavailable for this county. Local growers should conduct individual soil tests to determine if they need to amend for the high heat and 22.2 inches of annual rain.
Extended Drought Hits Hard
Brule County suffered through 37 weeks of drought over the past year, and the entire area is currently abnormally dry. To conserve water, consider taller mowing heights to shade the soil and reduce surface evaporation.
Heat-Resistant Varieties Required
Tall Fescue is a strong candidate here due to its deep root system and heat tolerance. Plant after the May 3rd frost to give your lawn a head start before the intense summer heat arrives in July.

- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
Fall
