From harvest to midwinter meals

Many Canadian households still rely on unheated basement rooms, dug cellars or cool pantry spaces to extend the life of potatoes, carrots, onions and squash. Success depends less on a single technique than on matching each crop to stable cold-humid or cool-dry conditions.

Root cellar conditions

Potatoes, carrots and beets keep longest in dark, humid spaces just above freezing. Ventilation prevents mould while preserving skin integrity.

Pantry temperature

Onions, garlic and winter squash prefer cooler indoor rooms with lower humidity than root crops. Separation reduces sprouting and rot.

Shelf life by crop

Storage duration varies with variety, harvest maturity and regional winter severity. Curing and sorting at harvest extend usable months.
