Answer: Fall, with its cooler temperatures and more abundant moisture, offers excellent growing conditions for many vegetables.These include beets, Chinese cabbage, cauliflower, celery, collards, green onions, potatoes, Bibb and leaf lettuce, mustard, parsnips, radishes, salsify, spinach, and Swiss chard.These vegetables include cabbage, broccoli, brussels sprouts, carrots, kale, leeks, rutabagas and turnips.Remember, too, that even when the tops of such vegetables as 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. .
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. .
Can you leave beets in the ground over winter?
Parsnips, carrots, turnips, kohlrabi, beetroot and swedes are all able to be left in the ground over winter, usually without losing any of your crops to rot, disease, or pest infestations.If you expect an extremely cold winter, with sustained temperatures of 25 degrees and below, it’s best to go ahead and harvest all of your root crops so as not to chance losing them due to freezing. .
Winter Kill Temperatures of Winter-Hardy Vegetables 2016
For several years, 2015, 2104, 2013, 2012 my friend and neighboring grower Ken Bezilla of Southern Exposure Seed Exchange and I have been keeping records of how well our crops do in the colder season.It’s worth noting that in a hoophouse plants can tolerate lower temperatures than those listed here: they have the pleasant daytime conditions in which to recover.25°F (-4°C): Chervil, chicory roots for chicons, and hearts, Chinese Napa cabbage (Blues), dill, endive (hardier than lettuce, Escarole more frost-hardy than Frisée), annual fennel, some mustards and Asian greens (Maruba Santoh, Mizuna, most Pak Choy, Tokyo Bekana), onion scallions (some much more hardy), radicchio.15°F (-9.5°C): Some beets (Albina Verduna, Lutz Winterkeeper), beet leaves, some cabbage (Kaitlin, Tribute), celery (Ventura) with rowcover, cilantro, endive, fava beans (Aquadulce Claudia), Russian kales, kohlrabi, some lettuce, especially medium-sized plants (Marvel of Four Seasons, Olga, Rouge d’hiver, Tango, Winter Density), curly leaf parsley, flat leaf parsley, large leaves of broad leaf sorrel, turnip leaves, winter cress.12°F (-11°C): Some beets (Cylindra,), some cabbage (January King, Savoy types), carrots (Danvers, Oxheart), most collards, some fava beans (not the best flavored ones), garlic tops if fairly large, most fall or summer varieties of leeks (Lincoln, King Richard), large tops of potato onions, rutabagas (if mulched), Senposai leaves (the core of the plant may survive 10F), some turnips (Purple Top), winter radish including daikon (may survive colder).10°F (-12°C): Beets with rowcover, Purple Sprouting broccoli for spring harvest, Brussels sprouts, chard (green chard is hardier than multi-colored types), a few varieties of cabbage (Deadon), some collards (Morris Heading can survive at least one night at 10F), Belle Isle upland cress, some endive (Perfect, President), young stalks of Bronze fennel, probably Komatsuna, some leeks (American Flag, Jaune du Poiteau), some head lettuce under row cover (Pirat, Red Salad Bowl, Salad Bowl, Sylvesta, Winter Marvel), large leaves of savoyed spinach (more hardy than flat leafed varieties), Tatsoi, Yukina Savoy.0°F (-18°C): Chives, some collards (Blue Max, Winner), corn salad (mache), garlic, horseradish, Jerusalem artichokes, a few leeks (Alaska, Durabel); some bulb onions, some onion scallions (Evergreen Winter Hardy White, White Lisbon), parsnips (probably even colder), salad burnet, salsify, some spinach (Bloomsdale Savoy, Olympia, Tyee).Austrian Winter Field Peas and Crimson clover (used as cover crops) are hardy down to -10°F (-23°C). .
Frost Tolerance of Vegetables, Edibles: Botanical Interests
Frost tolerance is a crop's ability to survive a frost or below freezing temperatures.Why are some plants more frost tolerant than others?Sweetening is one of a few strategies plants may have to avoid frost or freeze damage, and it is a strategy often seen in cool season vegetables.Also, the more mature the frost-tolerant plant, the better able it is to withstand frost or freezing. .
19 Frost Hardy Vegetables to Plant this Fall
With a little bit of planning, and preparation you can grow vegetables well into the winter months or even year round if you live in a warmer climate down south.But regardless of where you live, there are a few crops you can count on to withstand cooler temps, frost, and even sometimes snow.Although beets grow well during warm weather, the seedlings are established more easily under cool, moist conditions.The plant will withstand frost and can be harvested until a hard freeze strikes.Carrots can survive temperatures as low as 15 degrees Fahrenheit, but prolonged periods of cold results in long, pale roots.Carrots can survive temperatures as low as 15 degrees Fahrenheit, but prolonged periods of cold results in long, pale roots.Frost damage on leafy vegetables doesn't render the plant inedible like a disease.Snow can protect plants from extreme cold so that they stay in the garden longer.Parsnips are generally tolerant to 0 °F and will sweeten in flavor if hit with a light frost or two.To extend the harvest season & protect the crops from heavier frosts, just add a thick layer of straw. .
Snow Tolerant Vegetables
If plant cell damaging freezing temperatures accompany snow, protect crops with mulch, plastic tunnels, or cold frames.Crops that can survive under snow—but not sustained freezing temperatures or ice–include asparagus, rhubarb, beets, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, cress, rutabaga, spinach, endive, horseradish, kohlrabi, kale, leek lettuce, onions, parsley, parsnips, radishes, and turnips. .
Grow in the Snow: A Beginner's Guide to Overwintering
Plant cool-weather crops in the early to mid-fall, let them establish a root system in October and November, lie dormant during the cold and dark months, and then emerge in the spring.You can overwinter crops including beets, carrots, kale, spinach, and scallions, as well as some less-known hardy winter greens like claytonia, mache, and sorrel.Claytonia is known as “miner’s lettuce” and is a sweet salad green that is one of the first overwintering crops to emerge in the spring.During the winter months, something amazing happens to root crops like beets, carrots, and turnips if you leave them in the ground.This will prevent the lid of the frame from breaking under the weight of snow and ice, and allow for the automatic vent to open should there be a particularly warm day. .
