Frost dates, planting zones, soil types, and what actually thrives in Vermont — from mountains to coast.
Frost dates & zones
Vermont spans USDA zones 3b (Northeast Kingdom / Derby) to 6a (Bennington / southern VT valleys). Verify your exact zone and frost dates with your county Extension office — elevation and microclimates create real variation.

All Vermont soils need lime and compost — pH 4.5-5.5 is typical. Champlain Valley clay loam is the exception. Raised beds improve drainage and warmth on hill farms. UVM Extension soil testing available at low cost.
Know your soil
Vermont soils are thin, acidic, and rocky — classic New England glacial till over granite and schist. The Champlain Valley in western Vermont has the state's best agricultural soils — deeper, well-draining clay loam that is more forgiving than the rest of the state. River valley bottomlands have productive alluvial soils. Mountain and upland soils require patient amendment.
