Data Story
About Lawn Care in Beltrami County, Minnesota
Severe challenges in the North
Beltrami County faces a difficult lawn maintenance environment with a score of 36.9. As one of the few regions in USDA Hardiness Zone 3b, it is significantly tougher than both the national average and the state score of 63.9. The extremely cold climate and short growing window demand a specialized approach to turf care.
Cold winters and low rain
The county records just 1,805 growing degree days and an average of only 3 extreme heat days. Precipitation is limited to 25.6 inches annually, well below the 30-inch ideal for healthy lawns. These factors mean grass grows slowly and requires supplemental water to stay green through the brief summer.
Acidic and sandy soil profile
The soil pH is 5.18, indicating an acidic environment that can stunt grass growth and limit nutrient uptake. The ground contains 49.5% sand and only 8.3% clay, which often leads to fast drainage and nutrient leaching. Adding organic matter or compost is vital to help this soil hold onto water and fertilizers.
Managing a year of drought
Beltrami County has struggled with drought for 44 weeks over the last year, with 100% of the area currently abnormally dry. Although severe drought is currently absent, the low annual rainfall makes lawns highly vulnerable. Water deeply in the early morning to minimize evaporation loss in these dry conditions.
Targeting the short summer
Only the hardiest Zone 3 grasses, like Creeping Red Fescue, can survive the intense winters here. Seeding should occur quickly after the late spring frost on May 24 to maximize the short growing season. Be prepared for the first fall frost as early as September 20.

Seasonal Lawn Care Checklist
Spring
- Apply pre-emergent herbicide when soil reaches 55F
- Overseed bare spots once frost risk passes
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Mow at recommended height weekly
- 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
- Core aerate compacted areas
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
- Avoid walking on frozen turf
- Service mower and sharpen blades
- Plan spring soil amendments based on fall test
- Keep lawn clear of debris
