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. .
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.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.Grows slowly through the winter but will always bounce back in early spring. .
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-tolerant Garden Vegetables
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. .
How Extreme Cold Affects Pansies, Violas, Cabbage and Kale
You can help the surviving plants by fertilizing lightly once temperatures begin to warm in late February and early March.While they also are fairly hardy, and in most years will provide needed color and texture in winter months, this latest blast of cold probably killed most of them in the area. .
Curly Kale: Extra Cold Tolerance, Highly-Productive Crops
Light requirements: Full sun is ideal, but plants yield in part shade.Frost-fighting plan: Established plants tolerate hard frosts (temperatures below 28º F) and produce new leaves all winter long in zones 7 to 10.Common issues: Watch out for cabbageworms, harlequin bugs, slugs, grasshoppers, and cabbage aphids.Storage: Refrigerate unwashed leaves in a lightly damp paper towel slipped into a very loosely closed plastic bag and store up to 5 days. .
7 Ways to Protect Plants From Frost Damage ~ Homestead and Chill
Freezing, frosty weather can make gardening more challenging at times, but that doesn’t need to be a deal breaker – or mean certain death to your plants!From row covers and cloches to careful selection of plant locations and varieties, follow these simple frost protection tips to help extend your growing season.Thankfully, I have plenty of wonderful gardener friends that live in colder climates that were willing to share sage advice and photos for this article too.Young and tender plants are the most susceptible to frost damage, so they will need more special attention during a cold snap.Frost usually impacts fresh new growth and the outer perimeter leaves the most, but that doesn’t mean the plant is dead or won’t continue to grow.Tender plants have soft, succulent tissues and are easily damaged or killed by freezing temperatures (unless protected).Examples of tender plants include summer crops like tomatoes, basil, cucumber, squash, peppers, eggplant, along with citrus, avocado, succulents, most annual flowers and common houseplants.Hardy annual vegetable plants include common cool season crops like cabbage, broccoli, kale, cauliflower, Swiss chard, carrots, radishes, turnips, and beets.They do enjoy cold conditions but their thin leaves will become more easily damaged when exposed to frost (without protection) than tougher, thick-leaf hardy vegetables.Yet there are plenty of other wonderful fruit trees that will thrive in lower frosty zones with much less fuss, including apples, pears, and plums.Imagine you’ve spent weeks or even months raising seedlings that you grew from seed indoors.The process strengthens them, and reduces the risk of shock or injury that could otherwise be caused by wind, rain, direct sunlight, heat, or cold.Seedlings we raised in our greenhouse spending some time outside in the shade on a calm day, starting the hardening off process.Keep in mind that even properly hardened off seedlings are more susceptible to frost damage than mature plants.Even mature cool-season vegetable crops will appreciate the added protection of a cover when temperatures dip below freezing, especially for an extended period of time.Something as simple as an old bed sheet , blanket , drop cloth, roll of burlap, or sleeping bag can help protect plants from frost damage., , drop cloth, roll of burlap, or sleeping bag can help protect plants from frost damage.You could cut a large sheet of frost cover into smaller pieces that fit over individual garden beds.Some specialized frost covers are designed and shaped to fit neatly over shrubs or small trees, like this one.You could cut a large sheet of frost cover into smaller pieces that fit over individual garden beds.(like greenhouse plastic, or even a tarp) can be used in a similar manner as fabric row covers to protect plants from frost and snow.You can purchase cloches or turn average buckets, food storage containers, cut milk jugs, 2-gallon soda bottles, or other random materials into homemade ones!You can purchase cloches or turn average buckets, food storage containers, cut milk jugs, 2-gallon soda bottles, or other random materials into homemade ones!The higher the number, the thicker the fabric, and the colder the temperatures it is rated to protect plants from – and the more it will warm the soil below.A simple raised bed cold frame, created by my friend Crystal @wholefedhomestead who gardens in Wisconsin.If possible, keep row covers (blankets, sheets, etc) slightly elevated above the plants by supporting them on hoops, stakes, or other clever means.You can typically leave transparent cloches, sheet plastic supported on hoops, and specialized frost covers on during cold days as well.A prime example of using polytunnels (thick plastic supported on hoops) to protect and insulate garden beds.We support various row covers (including sheets for frost protection, insect netting or shade cloth) with these sleek garden hoops.For example, planting less hardy trees and shrubs near a west or south-facing wall will provide valuable radiant heat and create a space that is several degrees warmer than nearby open areas.Large shrubs, fences, boulders, and canopy cover from trees offer similar protection for nearby plants.Another excellent and simple DIY cold-frame design from my friend Kirsty @my_little_allotment in her UK garden, using sheets of corrugated greenhouse plastic.Applying a nice deep layer of organic mulch around the base of shrubs, young trees, evergreens, or tender perennials will help protect the plants from frost damage.You could even cover low-lying plants completely with a layer of fluffy mulch (such as straw) for a short period of time.Mulch adds a protective layer that insulates soil, holds in warmth, and can prevent the ground (and roots) from freezing.A few excellent mulch options include compost, small bark, wood chips, straw, and chopped leaves or leaf mold.My friend Crystal’s garden (@wholefedhomestead), preparing for a freezing Wisconsin night ahead using several frost protection methods – including bucket cloches over individual plants, and deep straw mulch in her garlic patch.It may sound a little counter-intuitive, but watering your garden before an exceptionally chilly evening can help protect plants from frost damage.Gardening in Minnesota, she is able to significantly extend her short growing season by using hoops and row covers to warm the soil and air around the plants.Even tender veggie plants may recover from leaf scorch, wilt and browning caused by frost. .
Tips for Growing Collard Greens in Winter
While freezing temperatures and a snow-covered ground may signal the main growing season is over, it doesn’t have to mean the end of fresh garden greens.These members of the Brassicaceae family are incredibly frost tolerant and can survive temperatures down to the upper teens.In fact, frost actually improves their taste as cold temperatures trigger the plant to convert the starches in the foliage to sugars which produces a sweeter flavor and a more tender texture.This incredibly hardy crop can continue to be harvested even after the leaves have frozen, which makes them an ideal choice to plant for a dose of healthy greens in the colder months.I once grew collard greens in my Zone 6 garden that survived through the winter without protection and resumed growth the next year!Your goal is to sow seeds in time so that your crop is ready to harvest after one or two light frosts but before the first killer freeze.In very warm locations, you can start seeds indoors to transplant out into the garden about eight weeks before your average first frost date.In colder regions, Zones 7 and below, there are a number of steps you can take to keep your collards producing for as long as possible into the winter months. .
