Root cellars are traditionally used to keep produce consumable through the winter months when fresh fruits and vegetables aren’t available. However, with modern-day refrigeration.
Depending on your available space, you could have a few great areas hiding around your home with ideal conditions for storing vegetables. Consider your spring, summer, and favorite fall vegetables. Depending on the variety, they might require different humidity, temperature, etc.
Attics and basements stay very cool and dry throughout the winter, ideal for storing produce in a straw-filled cardboard box. Similarly, garages also work as long as you ensure the raw vegetables don't freeze.
If you have any extra freezer space, freezing your harvest will keep it fresh-tasting, and usable throughout the winter months. However, it’s not as simple as throwing your fruits and veggies in the freezer and forgetting about them.
