Data Story
About Lawn Care in Todd County, Minnesota
A Cooler Climate for Todd County
Todd County’s lawn difficulty score of 62.2 is just below the state average of 63.9. Located in Hardiness Zone 4a, the county deals with a shorter growing season and cooler average temperatures. While easier than the national average, the environment requires more attention to winter hardiness.
Short Seasons and Cooler Days
With only 1,952 growing degree days, your grass has a much shorter window to thrive than in southern Minnesota. The season is framed by a late frost on May 13 and an early first frost on September 27. However, the 31.0 inches of precipitation provides the ideal amount of natural moisture for cool-season grasses.
Sandy Ground and Low pH
The soil is 62.4% sand with a pH of 5.78, which is more acidic than the ideal range for turf. This high sand content means water and nutrients move through the soil very quickly. Regular applications of organic matter or compost are necessary to help this soil hold onto the moisture your grass needs.
Rising Dryness in Central Soils
Currently, 55.0% of the county is considered abnormally dry, following 11 weeks of drought over the last year. In sandy soils like these, even a short dry spell can lead to browning and dormancy. You should prioritize early morning watering to maximize absorption before the sun gets too high.
Selecting Hardy Grass for Zone 4a
Because of the May 13 frost date and cooler 1,952 GDD, select cold-hardy varieties like Creeping Red Fescue. These species handle the acidic, sandy soil of Todd County better than more sensitive turf types. Start seeding as soon as the soil warms in late May to give roots time to establish.

- 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
