Data Story
About Lawn Care in Meagher County, Montana
Struggling in the High Country
A lawn difficulty score of 27.7 makes Meagher County a tough place for lush yards. In Zone 4b, the environment is nearly twice as difficult to manage as the national average of 50.0.
A Very Short Season
With a late frost on June 11 and an early one on September 11, the growing season is exceptionally short. Only 7 extreme heat days occur, but the 16.2 inches of rain isn't enough to sustain turf without help.
Building a Better Foundation
Localized soil data is missing, but regional trends suggest you likely need to add organic matter to improve nutrient retention. Soil testing is highly recommended to determine the best amendments for this 4b zone.
Severe Drought Conditions
Nearly 60% of the county is in severe drought, part of a 51-week dry spell over the last year. During these times, let your grass grow longer to protect the soil from moisture loss and heat stress.
Planting for Cold Survival
Sheep fescue and other cold-hardy bunchgrasses are ideal for Meagher's short, cool summers. Start your planting in mid-June once the risk of frost has finally passed.
