Lawn Care Timing Guides for Wyoming
- Summer Lawn Dormancy: Keep Cool-Season Grass Alive in Heat
Cool-season grass slows once 2-inch soil sustains 75°F and goes dormant near 85°F.
- When to Apply Grub Control: The 65-70°F Soil Window
Apply preventive grub control (chlorantraniliprole or imidacloprid) before eggs hatch, when 2-4 inch soil holds 65-70°F: late June through July in most regions.
- Lawn Fungus by Temperature: Brown Patch, Dollar Spot & More
Brown patch and Pythium strike when humid nights hold above 68°F on lush, over-fertilized turf; dollar spot, red thread, and rust hit slow-growing lawns at 60-85°F.
- Grass Seed Germination Soil Temperature by Species
The soil temperature each grass species needs to germinate, from 15+ university extensions: tall fescue and perennial ryegrass 68-86°F, Kentucky bluegrass 59-86°F, fine fescue 59-77°F, cool-season 50°F trigger, warm-season 65°F.
Soil Temperature FAQ for Wyoming
What is the current soil temperature in Wyoming?
The current average 2-inch soil temperature across Wyoming is 69°F, based on 4 USDA and NOAA monitoring stations. Readings range from 61°F to 80°F depending on location and elevation.
When should I apply pre-emergent in Wyoming?

When can I plant grass seed in Wyoming?
Cool-season grasses (fescue, bluegrass) can be seeded when soil holds between 50 and 65°F. Warm-season grasses (bermuda, zoysia) need soil above 65°F. Timing varies by location, so check your city's planting window for the dates specific to your area.
