Gardening in Vermont

Everything we have worked out for Vermont: what to plant and when, which varieties finish in time, the pests that actually turn up here, and the jobs that pay off month by month. We also cover the rest of the property, from lawns and soil to home care and energy, because a garden rarely stops at the vegetable bed.

The numbers first, because everything else follows from them. Measured at the weather station in Burlington, the last spring freeze runs April 30 to May 10 and the first fall freeze runs October 3 to October 13, USDA zones 3b-5b, 2,644 growing degree days in the year.

Garlic does well: 30.4 weeks below 40 °F, comfortably past the six it needs to form a proper head.
