Potato Varieties That Suit Quebec
Quebec’s growing window opens late and can close in a hurry once summer heat builds, so the varieties that suit the province are early- and mid-season…
Home & garden, state by state
Everything we have worked out for Quebec: 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 Montreal, the last spring freeze falls around May 6 and the first fall freeze falls around October 5, 2,268 growing degree days in the year.
That is enough for early varieties, tight for anything late. Garlic does well: 30.4 weeks below 40 °F, comfortably past the six it needs to form a proper head.

Across most of Quebec, March means the ground is still frozen or buried in snow, so the direct answer is: nothing goes into open soil yet.
By June, Quebec’s growing season is finally wide open. The province’s average last spring frost sits around May 6, so a month later most tender crops can…
July in Quebec sits deep inside the growing season, well past the average May 6 last frost and still three months from the average October 5 first frost…
January in Quebec means frozen ground from the Ottawa Valley to the Gaspé, so nothing goes into open soil this month.
