About Lawn Care in Goshen County, Wyoming
Hot Summers and Dry Skies in Goshen
Goshen County faces a lawn difficulty score of 28.5, placing it well below the national median of 50.0. The combination of low rain and high heat in hardiness zone 5a creates a high-maintenance environment for any homeowner.
The State's Heat Leader
With 42 extreme heat days a year, Goshen County is significantly hotter than the state average of 23 days. While 14.7 inches of rain is slightly better than some neighbors, the 2555 growing degree days mean your grass will grow fast and require frequent watering.
Customizing Your Soil Care
No specific soil data is available for Goshen, making individual yard testing a vital step for success. To combat the 42 days of extreme heat, focus on adding top-dressing to your soil to prevent it from cracking and to help it retain what little moisture it gets.
High Drought and Heat Stress
The county saw 40 weeks of drought over the last year, and 44.1% of the area is currently in severe drought. Effective management includes using a mulching mower to return nutrients to the soil and reduce water evaporation by up to 30%.
Seeding for a Sizzling Summer
Tall Fescue is a great choice here as it handles heat better than most cool-season grasses. Ensure your new lawn is established shortly after the May 14th frost so it can survive the intense heat that typically arrives by late June.
