Garlic Varieties That Suit Saskatchewan Winters
Saskatchewan growers should plant hardneck and softneck garlic in late August, using Saskatoon’s frost data and disease-temperature ranges to choose varieties and timing.
Home & garden, state by state
Everything we have worked out for Saskatchewan: 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 Saskatoon, the last spring freeze falls around May 18 and the first fall freeze falls around September 18, 1,549 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.

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.

Garlic planting in Saskatchewan runs in late August, worked out from Saskatoon’s average first fall frost rather than a set date.
Saskatoon’s winters clear the cold garlic needs to divide, but the average September 18 frost date is a midpoint, not a safe planting deadline.
Saskatchewan’s frost-free season averages 122 days at Saskatoon, and this guide gives transplant dates, variety picks, and the math to ripen fruit before fall frost.
Saskatoon’s mean frost dates set the tomato calendar for Saskatchewan, and this page shows how to count backward from that window to transplant and seed-start dates.
Saskatoon’s mean frost dates set the 123-day season used here to rank named tomato cultivars by days to maturity and margin before fall frost.
