Home & garden, state by state
Everything we have worked out for Nunavut: 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 Rankin Inlet, the last spring freeze falls around June 19 and the first fall freeze falls around September 13, 159 growing degree days in the year.
That is little accumulated warmth: tomatoes need a tunnel or a greenhouse here, whatever the frost dates suggest. Garlic does well: 43.5 weeks below 40 °F, comfortably past the six it needs to form a proper head.
