Data Story
About Lawn Care in Lamoille County, Vermont
Tough Turf Tasks in Lamoille
Lamoille County faces the steepest challenge with a lawn difficulty score of only 35.2. In hardiness zone 5a, residents must contend with environmental factors far more demanding than the state average.
Excessive Rain and Short Seasons
Lamoille receives a massive 58.1 inches of annual precipitation, which can lead to drainage issues and fungal growth. Combined with a low 1658 growing degree days, grass has less time to recover from the wet, cool conditions.
Highly Acidic Soil Foundation
A soil pH of 4.51 is much lower than the ideal 6.0 range, requiring significant soil amendments. The low clay content of 5.3% means the soil may not hold onto lime as long as other regions.
Surprising Dry Stretches
Despite the high rainfall, the county spent 30 weeks in drought last year, and 45.3% is currently abnormally dry. Mulching clippings back into the lawn is essential to help the soil retain moisture during these swings.
Maximize Your Short Window
Stick with very hardy Fine Fescues that can handle both the moisture and the cold. With a late spring frost on May 23, patience is key before starting your spring lawn renovation.
