It's a nice, summery day today, but this time of year, that could turn on a dime. Over the next few weeks, keep an eye out for low overnight temperatures, and bring in your crops when frost threatens them.
But some of your crops can tolerate a bit more cold than others. Here are some guidelines from the National Garden Bureau:
Likely damaged by light frost: Beans, cucumbers, eggplants, muskmelon, New Zealand spinach, okra, peppers, pumpkins, summer squash, sweet corn, tomatoes, watermelon, amaranth, and winter squash (plants).
Can withstand light frost: Artichokes, beets, carrots, cauliflower, celery, chinese cabbage, endive, lettuce, parsnips, peas, swiss chard, escarole, arugula, bok choy, mache, and radicchio.
Can withstand hard frost: Broccoli, Brussels sprouts, cabbage, collards, kale, kohlrabi, mustard, onions, parsley, peas, radishes, spinach, turnips, leeks, and sorrel.
To clarify, a light frost means temperatures dip to just below freezing, between 28 to 32 degrees. A hard frost is indicated by temperatures below 28 degrees.
