Can You Eat Fresh Garden Vegetables After They’ve Been Exposed to Frost?

November 8, 2016 by Jeanne

Can you eat garden vegetables after they’ve been exposed to a hard frost? Here’s what you need to know about frost and the vegetable garden.

Can You Eat Garden Vegetables After a Frost?

Yes, you can eat vegetables after a frost has come to the garden. Frost or freezing temperatures freezes the water crystals inside the plant’s cells. Depending on your garden, the veggies may be fine to eat or they may not be.

You will have to use your judgment, but here is a basic guideline.

  • Warm or hot season vegetables like tomatoes, peppers, and green beans may be less desirable after a frost. Peppers tend to get mushy and should be thrown away. Tomatoes may or may not be okay; feel them. If they are squishy, bruised, or do not look right, throw them out. Green beans that still feel firm to the touch can be harvested and refrigerated, but use them quickly.
  • Lettuce, chard, and other greens are usually able to withstand a light frost without a problem. Chard, mustard greens, collard greens and kale are typically fine after a frost. Use your eyes and your head; if it looks okay, it should be fine. Anything that’s wilted or brown, throw it out.
  • Broccoli, cabbage, Brussels sprouts, cauliflower actually benefit from frost. Brussels sprouts and broccoli taste better after a frost, actually! So leave them in the garden until you’re ready to harvest them or a cold spell (consistent temperatures under 40) threatens.

Cabbage usually survives several light frosts without a problem.

[Tweet “When in doubt, throw it out – don’t eat anything from the garden if you’re not sure it’s still good. Cold weather crops like cabbage, kale, cauliflower and broccoli, however, should still be edible and tasty after a frost.”]

Happy gardening. Keep growing!

  1. Fall Vegetable Garden: How to Grow Broccoli - Home Garden Joy says:
    August 29, 2017 at

    […] After 85 days or so, broccoli begins to form small, tight green flower buds. This is the part that you eat – the tight flower buds. Harvesting should be timed if at all possible, to coincide with the days right after the first frost. […]
