Everything we have worked out for New Brunswick: 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 Moncton, the last spring freeze falls around May 23 and the first fall freeze falls around October 2, 1,594 growing degree days in the year.
That is enough for early varieties, tight for anything late. Garlic does well: 34.8 weeks below 40 °F, comfortably past the six it needs to form a proper head.
