Lawn Care Timing Guides for North Dakota
- 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.
