What these dates mean in New Hampshire

Frost-date caveat: these are published ranges for New Hampshire. A northern or high-elevation site will run later than a southern or low one, and a cold wet spring can push planting past the window. Timing is relative to last spring frost (central NH: about Memorial Day, a conservative estimate); frost dates and local conditions vary. Check your last spring frost and soil temperature, and confirm with your county extension office.
