When to Sow Carrots in Yukon: Counting Back From the Last Frost
Carrots go into the ground before the last frost, not after. The seedlings tolerate cold that would wreck a tomato start.
Home & garden, state by state
Everything we have worked out for Yukon: 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 Whitehorse, the last spring freeze falls around June 5 and the first fall freeze falls around August 25, 600 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: 39.1 weeks below 40 °F, comfortably past the six it needs to form a proper head.

Figures from Environment and Climate Change Canada. A state is not one climate: elevation, a large lake or the coast can move these dates by two weeks either way, so check your own county with the extension service before you spend money.
