Fall Vegetable Gardening in Canada
On this page
Start from your season length
Your garden’s season is its frost-free period: the days between the average last spring frost and the average first fall frost. In the fall the second date matters most, because whatever you still want to harvest needs its days to maturity to fit before it. Your provincial agriculture department publishes frost dates for your area.
Hardiness zones measure something else: how severe your winter is, for choosing perennials that must survive it, such as rhubarb and asparagus.
Stretching the end of the season
Floating row covers give crops some frost protection and extend the season, a couple of degrees’ worth. Each guide covers frost protection for its crop: lettuce, spinach, kale, Swiss chard.
Garlic before freeze-up
Across most of Canada garlic is planted in the fall, before freeze-up, and spends the winter in the ground to give next year’s crop. A deep straw mulch helps it through. Provinces give different planting windows, so follow your own province’s date. See how to grow garlic in Canada.
Mulch the late crops
A mulch on late crops conserves soil moisture and smothers weeds, so the last weeks of the season go into growing, not weeding.
Lifting and storing roots
Root crops keep best cold and moist, somewhere that never freezes, so they do not shrivel. That is the storage to aim for with carrots, beets and parsnips.
Fall, month by month
Fall questions
Is it too late to sow anything in the fall?
Only if the crop’s days to maturity no longer fit before your average first fall frost.
Do row covers really help?
Yes: they add a couple of degrees of frost protection and extend the season.
When does garlic go in?
In the fall, before freeze-up, in most of Canada.
