Data Story
About Lawn Care in Caledonia County, Vermont
Challenging Conditions in Zone 4b
Caledonia County has a lawn difficulty score of 46.3, making maintenance more difficult than the national average. As a hardiness zone 4b region, the shorter growing window and colder winters present unique hurdles for local lawns.
Cooler Summers and Short Seasons
The county records just 1737 growing degree days and only 2 extreme heat days, reflecting a very cool climate. While 44.3 inches of rain provides plenty of water, the limited warmth restricts the total growth potential each year.
Acidic Soil and Low Clay
The soil pH of 4.51 is quite low, necessitating aggressive lime applications to support healthy turf. Low clay content of 3.9% means the soil may struggle to hold onto nutrients, requiring careful fertilization strategies.
Extended Periods of Dryness
The county spent 30 weeks in drought over the last year, and 100% of the area is currently listed as abnormally dry. Monitoring soil moisture is critical, as even these cool regions can face significant turf stress during long dry runs.
Focus on Hardy Species
Select the most cold-tolerant grass varieties like Creeping Red Fescue for this 4b zone. Aim to seed after May 10 to maximize the growing window before the first fall frost arrives in early October.

Seasonal Lawn Care Checklist
Spring
- Apply pre-emergent herbicide when soil reaches 55F
- Overseed bare spots once frost risk passes
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Mow at recommended height weekly
- 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
- Service mower and sharpen blades
- Plan spring soil amendments based on fall test
- Keep lawn clear of debris
