These 8 frost resistant vegetables are perfect for your fall garden or for an early spring planting.Frosts will actually increase the sugar content, effectively eliminating the bitter taste so often experienced in summer sprouts.In fact, you will find they do best in cool fall weather and are rather disappointing in a summer garden.A very hardy vegetable, kale not only tolerates the cold, but it has no problems with insects like cabbage can have.It can also be an early spring crop if you grow under a row cover or cold frame to protect it from extremes.Late season seedlings can be mulched heavily for the winter when temperatures reach freezing for a nice spring crop.The top leaves will die back if temperatures drop below 10 degrees or so, but the root itself will still be good to eat. .
Warning: These Vegetables Will Not Survive a Frost
When you know and understand the concept of frost tolerant vegetables you can save yourself from the very traumatic experience of going out to your garden to find a bed full of dead plants.By late May my climate has settled into pretty stable nighttime temperatures and we rarely get a frost after the third week of May.At the end of the summer as fall approaches, the same temperature fluctuations start up again and eventually our first frost will arrive, usually around the beginning of October.If you make this mistake and plant too early you might come out to your garden one morning to find a bunch of dead seedlings that have been killed by cold weather.In contrast, at the end of the season as fall approaches, many of our hot weather crops like tomatoes, peppers, and eggplant are large and robust and are pumping out lots of fruit for our dinner tables.But, as your garden approaches your average first frost date, there’s a high likelihood that a night will arrive where the temperature falls to 32 F.In fact, some of them, like arugula, cilantro, and spinach prefer being planted in early spring because they grow better in cooler weather.Even though these vegetables are frost hardy, you should wait to plant them if a big snowstorm or extremely cold weather is in the forecast.In the fall, you’ll be pleasantly surprised at how well the frost tolerant vegetables are doing as the nighttime temperatures start decreasing.As you’ll see in the lists below, once the temperatures dip into the lower 20’s and teens F, most of the plants will eventually die without the added protection of row covers, cold frames, and low tunnels.Vegetables that can withstand a light freeze/frost (28—32 F): Bok choy Cauliflower Celery Chinese Cabbage Lettuce (depends on variety) Peas. .
How to Grow Winter Cabbage
These names refer to the late season types that have better cold tolerance than others, and can provide you with a fresh harvest from November right through to February or March.You might be surprised to learn that the main limiting factor for growing cabbage in winter isn’t cold, but light.In the late fall and winter months, the decrease in daylight slows plant growth.An important term to know if you’re planting for a fall and winter harvest is what organic farmer and educator Elliot Coleman refers to in “The Winter Harvest Handbook: Year Round Vegetable Production Using Deep-Organic Techniques and Unheated Greenhouses” as the Persephone Period.To determine when you should plant late-season cabbage seeds, count back 12-14 weeks before the Persephone Period begins in your area.Cultivars to Select When choosing your varieties of this cruciferous veggie to plant late in the year for a winter harvest, check seed packets carefully.Do your research before you plant, and select varieties that are labeled “winter,” “cold season,” “overwintering” or “storage” to ensure success.‘Brunswick’ Cold hardy, drought tolerant, and easy to store, seeds are available in a variety of packet sizes from Eden Brothers.It is quick to mature, frost hardy, and even won an Award of Garden Merit for “reliability and good performance” from the Royal Horticultural Society.Provide Protection from Cold Most cabbages can survive light frosts, but when temperatures dip below 20ºF this can damage them.Make sure the sides are weighted down and the ends gathered to provide maximum protection against the elements.And if your plants are growing in containers, you can simply bring them inside and place them by a sunny window when very low temperatures are forecast.According to Grethen Voyle at Michigan State University Extension, cabbages can be harvested even if they appear frost damaged.If you pull your cabbage out of storage and discover some rotten leaves, simply peel back the bad ones until you find a healthy-looking head underneath.This recipe from our sister site, Foodal pairs cabbage, potatoes, and white beans for a simple yet filling meal. .

Does Frost Kill Vegetable Plants? (Which Ones Can Survive
Frost will kill many tropical vegetable plants, including tomatoes peppers, and squash.However, some cold-tolerant vegetables can survive frost, including broccoli, cabbage, and carrots.If you have time to prepare, you might be able to extend the growing season by protecting your plants from cold.Frost will kill many tropical and warm-season vegetable plants, such as peppers and tomatoes.According to Rutgers University, tomatoes are very sensitive to frost, which will kill them (unless they have cold protection – more on this later).You can check the last spring frost date for your area with this resource from the Old Farmer’s Almanac.A light frost will not kill potato plants, but may damage the foliage.However, according to the University of Maryland Extension, a heavy frost or freeze will kill potato plants.If only the foliage above ground is killed in spring, the plant will send up new growth if it has enough energy to do so.That way, you will avoid heavy frost that can kill the shoots after they emerge from the soil.You can check the last spring frost date for your area with this resource from the Old Farmer’s Almanac.However, according to the North Carolina State University Extension, lower temperatures will start to cause damage:.However, if you want to avoid losing your flowers and fruit, cover strawberry plants when a late spring frost threatens (more on this later in the article).Even a light frost will damage or kill pepper plants unless you provide cold protection.According to the University of Nebraska-Lincoln, pepper plants turn black and the fruit rots and becomes mushy after frost exposure.You can check the last spring frost date for your area with this resource from the Old Farmer’s Almanac.According to the Iowa State University Extension, even a light frost will kill the vines of a pumpkin plant (although the fruit will be ok).A hard frost will kill the pumpkin vines and has the potential to damage the fruit.The University of Nebraska-Lincoln suggests harvesting pumpkins before temperatures drop into the mid to low 20’s Fahrenheit (-7 to -3 degrees Celsius).A spring frost can easily kill young pumpkin plants.To avoid this, transplant pumpkin seedlings outdoors 4 weeks after the last spring frost date.You can check the last spring frost date for your area with this resource from the Old Farmer’s Almanac.Sweet corn is frost sensitive, so cover it as temperatures approach 35 degrees Fahrenheit.For example, if you have a low-lying part of your garden (where cold air settles), the temperature can be a few degrees colder than nearby areas.There are a few different ways to protect your plants from frost and cold weather, including:.Cloche – a cover (often made of plastic) that protects a young plant from cold, wind, and pests.– a cover (often made of plastic) that protects a young plant from cold, wind, and pests.Row Cover – a lightweight and flexible sheet of fabric that keeps plants a bit warmer when cold weather threatens.– a lightweight and flexible sheet of fabric that keeps plants a bit warmer when cold weather threatens.Cold Frame – a small structure like a mini greenhouse, used to trap heat from sunlight in the air and keep plants warm.– a small structure like a mini greenhouse, used to trap heat from sunlight in the air and keep plants warm.It can hold taller plants and keep them warmer than the outside air in both the fall and spring.You can learn more about these cold protection methods (along with information on where to buy them or how to build them) on my resource page here.According to the Utah State University Extension, keep plants from coming in direct contact with a plastic sheet used for frost cover.You also know how to protect your plants from cold to extend the growing season and harvest more vegetables. .

Temperatures of 26-31 degrees F. may burn the foliage but will not kill broccoli, cabbage, cauliflower, chard, lettuce, mustard, onion, radish, and turnip.
Top 15 Cold-Tolerant Vegetables for Fall & Winter Gardening
When I talk about crops that can handle the cold, they are usually grouped together and labeled Cold-Hardy or Cold-Tolerant vegetables.Crops that can handle light frosts include lettuce, swiss chard, arugula, radishes, beets, chinese cabbage, collards, cauliflower, celery, turnips, and green onions.Crops that can take hard frosts include kale, cabbage, brussel sprouts, spinach, parsnips, carrots, mache, and claytonia.These are general numbers and individual crop temperature kills can vary based on location.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.The loophole that I’m referring to is specific varieties within crop families that are bred to be cold tolerant.My first experience with the marvel of specific crops bred for cold tolerance was winter density lettuce.If you have some favorites you’ve tried that aren’t on my list, leave a comment, I’d love to hear about it.*Rouge D’Hiver– This is a red romaine that is as cold tolerant as Winter Density Lettuce.*Brunswick cabbage– I’ve had this cabbage it last till mid January in our 6b zone with very little damage.Remember to start this one early enough that it forms a head before the daylight hours get too short.It has red tinged outer leaves that make this both ornamental and edible.*Bloomsdale Longstanding– Even though this isn’t bred for cold tolerance this spinach almost always overwinters (even without a low tunnel) in my zone (US 6b).*Winter Bloomsdale– A more cold tolerant version of the original bloomsdale longstanding spinach.*Giant Winter-Heavily Savoyed making it a perfect very cold tolerant crop lasting to 5ºF.*Vit Mache is also known as corn salad, is a great little winter green that are incredibly cold tolerant.*Purple Top Turnips can’t handle too much frost even with plenty of mulch (speaking from experience).Where they do shine in the winter garden is when stored at cool temperatures they last for months.It’s a hybrid variety that does well in cold and is fast growing (ready in 38 days).*Yellow Heart Winter Choy A very cold tolerant chinese edible green.Claytonia A wild edible in many areas of the US, this plant is incredibly cold hardy.Bolero A great choice for cold weather but a real winner when it comes to storage for long periods of time. .
How Do I Grow Cabbage?
Cabbage is a brassica crop — related to broccoli, cauliflower, kale and Brussels sprouts — that thrives in cold.Because of its frost tolerance, cabbage is perfect for starting your gardening season early in spring or for extending it into the fall.On the other hand, in hot weather, cabbage will “bolt,” which means it will send up a flower stalk before the plant is ready to harvest.A bolted cabbage will turn bitter and won’t form the head that gardeners desire.In regions with a short growing season, getting a head start indoors is the preferred method.The key to a successful spring cabbage harvest is to plant seeds or seedlings early enough so they mature before the heat of summer sets in.In an area that gets full sun, plant seedlings or sow cabbage seeds into fertile, well-drained soil.Also, overcrowded plants will have inadequate air circulation, which will make them more prone to disease.For a little color in the garden and on the plate, try split-resistant and later-maturing “Ruby Ball,” a reliable and consistent favorite in field trials.Be on the lookout for small white butterflies casing out your plants in mid-spring and early fall.These are cabbage butterflies, and when they flutter above your garden, that’s a telltale sign they’re looking for a place to lay their eggs, which will become the worms that eat the leaves.You don’t have to keep it on all the time (you can since cabbage is not dependent on pollinators to mature) but leave it on at least until the plant is well on its way and toughened up in the garden.Wet foliage provides an ideal environment for many of these pathogens, so watering around the base of the plants is the preferred method.If you find diseased cabbage in your garden, the best control method is to remove the affected plants to reduce the spread.It is important to practice crop rotation so any remaining pathogens will not infect plants in the next few seasons.Cabbage heads are ready to harvest when they have grown to full size and firmed up.Make two cuts through the top of the remaining stalk, about ¼ inch deep (like a plus sign).These new heads won’t get as large, but if they have time to mature before heat or extremely cold temperatures set in, you could have a second harvest from the same plant.Sign up to receive gardening resources, eBooks and email updates on the joegardener podcast and more.The selection of all items featured in this post and podcast were based solely on merit and in no way influenced by any affiliate or financial incentive, or contractual relationship.At the time of this writing, Joe Lamp’l has professional relationships with the following companies who may have products included in this post and podcast: Rain Bird, Corona Tools, Milorganite, Soil3, Exmark, and Wild Alaskan Seafood Box. .
