Hardy Vegetables That Survive the Frost

Plenty of options among hardy and semi-hardy crops.

Fall, with its cooler temperatures and more abundant moisture, offers excellent growing conditions for many vegetables. Yes, beans, cucumbers, eggplant, musk melon, okra, peppers, pumpkins, squash, sweet corn, sweet potato, and tomatoes will all be damaged by even a light frost, but many other crops will survive. These can best be divided into two categories: semi-hardy and hardy.

Beets are considered a semi-hardy vegetable.

Semi-hardy vegetables are those that can survive repeated light frosts in the 30-32˚(F) range. These include beets, Chinese cabbage, cauliflower, celery, collards, green onions, potatoes, Bibb and leaf lettuce, mustard, parsnips, radishes, salsify, spinach and Swiss chard. In fact the flavor of some of these, such as collards and parsnips, is much improved by exposure to a spell of below-freezing temperature.

Cabbage can be counted among the most cold-tolerant hardy crops.

Hardy vegetables are those that can survive temperatures as low as 20°(F) before finally succumbing. These vegetables include cabbage, broccoli, Brussels sprouts, carrots, kale, leeks, rutabagas and turnips. Upon thawing out, these hardy vegetables will continue to grow between freezes.

Remember, too, that even when the tops of vegetables like carrots and turnips are killed by cold, the roots will remain in good condition if the plants are mulched with a generous layer of insulating material, such as hay or leaves. This mulch will prevent the ground itself from freezing and allow you to harvest the fresh roots as you wish during the winter. (You may, however, find that voles discover and enjoy your cache of overwintering produce first.)
