There is almost always color somewhere in Vermont during that period.
Earliest colors appear in the Northeast Kingdom and along the spine of the Green Mountains.
Latest colors are in the Champlain Valley and the Lower Connecticut River Valley and Bennington County. Look for pockets of brilliant red early in red maple wetlands along roads. The weather in the spring of 2001 produced a normal crop of green leaves. We had a mix of wet and dry weather quite typical for the season. The dry spring early, slowed leaf opening slightly and a minor infestation of pear thrips chewed some leaves.
