Frost dates, planting zones, soil types, and what actually thrives in Massachusetts — from mountains to coast.
Frost dates & zones
Massachusetts spans USDA zones 5a (Berkshire highlands) to 7a (Cape Cod / Islands / South Shore coast). Verify your exact zone and frost dates with your county Extension office — elevation and microclimates create real variation.

Virtually all MA soils need lime — most are pH 4.5-5.5 and need to reach 6.0-7.0 for vegetables. Add compost heavily. Sandy Cape Cod soils need fertilizer every season. UMass Extension soil testing at Amherst is the standard for New England.
Know your soil
Massachusetts soils are predominantly thin, rocky, and acidic — glacial till scraped thin across the state. The Connecticut River valley in western MA has better alluvial soils. Cape Cod and the South Shore have sandy, acidic soils ideal for cranberries and blueberries. Urban Boston soils are heavily disturbed and often contaminated with lead and heavy metals.
