![]() The loophole that I’m referring to is specific varieties within crop families that are bred to be cold tolerant. No, it’s not a greenhouse, or a low tunnel, though those definitely extend the season. ![]() There is a loophole of sorts that will allow you to have certain varieties that should really be dead after reaching a certain temperature to continue on living. There is one really cool and really important thing to note here. These are general numbers and individual crop temperature kills can vary based on location. Frost kills the tops but the roots are still good. Crops that can take hard frosts include kale, cabbage, brussel sprouts, spinach, parsnips, carrots, mache, and claytonia. These would be crops that can several frosts and survive down to 20º and below. Next is very cold and winter hardy crops. Crops that can handle light frosts include lettuce, swiss chard, arugula, radishes, beets, chinese cabbage, collards, cauliflower, celery, turnips, and green onions. Light frosts would be in the 28-32✯ range. It covers such a wide range of temperature that they are usually put into two different groups, semi cold hardy which can take light frosts and cold hardy which can survive to 20✯ and below.įirst let’s talk about the crops that can take several light frosts. When I talk about crops that can handle the cold, they are usually grouped together and labeled Cold-Hardy or Cold-Tolerant vegetables.Ĭold Hardy vegetables can be killed anywhere from 30✯ all the way down to -5✯ and possibly lower. These crops need to be able to handle frost and lower temperatures. As a year-round gardener, I grow many vegetable crops in the garden to feed us in fall and winter.
