A well-stocked root cellar by November means food security through March. But getting there requires the right crops, timed harvests, and proper curing before storage.
The Critical Importance of Curing
Most storage vegetables must be cured before cellaring — a process that hardens their skin and heals minor wounds, dramatically extending storage life.
Potatoes: cure at 50–65°F for 10–14 days. Store at 38–40°F, very high humidity, in complete darkness. Winter squash and pumpkins: cure at 80–85°F for 10 days, then store at 50–55°F. Onions and garlic: cure by hanging in a warm, dry, well-ventilated space for 2–4 weeks.
Harvest Timing
Harvest after the first light frost but before a hard freeze. Light frost actually improves the flavor of carrots, parsnips, and beets by converting starches to sugars. Potatoes should be harvested when the vines die back naturally.
Storage Quantities Per Person
For a family of four eating primarily from storage for 6 months: 200 lbs potatoes, 50 lbs sweet potatoes, 100 lbs winter squash, 50 lbs carrots, 40 lbs beets, 30 lbs onions, 20 lbs garlic.
