If you click on an affiliate link and make a purchase, we receive a small commission at no extra cost to you.But this healthy veggie that is high in vitamin C and fibre, has a dependable spot in my fall recipe repertoire.There are dozens of cabbage varieties to choose from, and both chefs and home cooks probably all have their own particular favourites that they use in various hot and cold dishes.Cole crops is another broad term that envelops the cultivated varieties of the Brassica family, which also include Brussels sprouts, kale, kohlrabi, collard greens, broccoli, and cauliflower.After filling with your seed-starting mix, plant three or four seeds per cell about a quarter of an inch (1/2 cm) deep.If you plan ahead for succession planting, you can direct-sow seed in the ground around mid to late summer for a fall crop.However after being discouraged during so many growing seasons by the presence of cabbage moths and worms, I decided to use the floating row cover as pest prevention, too.I put it over the raised bed that also featured Brussels sprouts and kale (also tasty to cabbage worms), as well as root veggies that didn’t need pollinators to grow and left it there for much of the summer.This extra step was an acceptable part of my routine, because it meant I wasn’t surveying damage each morning.Cabbage heads can split for a few reasons, a heavy rain or drought being common causes.Too much soil moisture, often caused by heavy fall rains, for example, can result in split heads.If Mother Nature cooperates, you want to aim for your soil to be evenly moist closer to harvest time.Once a cabbage head has split, harvest it immediately, and eat as soon as possible, because you won’t be able to store it for as long.For gardeners who haven’t grown cabbages before, fast-maturing varieties, like Early Jersey Wakefield, are generally recommended. .
How to Plant and Grow Cabbage
Brassica oleracea var.capitata Cabbage is one of my all-time favorite cool weather crops to grow in my garden.I enjoy eating them raw in salads or cooked in stir fries, and I especially love them fermented as sauerkraut.Heading cabbage has been a part of the human culinary story for a very long time and was likely domesticated sometime around 1000 BC where it was developed from wild cabbage (Brassica oleracea var.Later, other cultivars of Brassica oleracea were developed into the red cabbage (Brassica oleracea var.Perhaps best grown from seedlings, start plants early in spring, about 8 to 10 weeks before the last expected frost, so you can harvest before the summer gets too hot.For fall plantings, start seedlings in summer about 12 to 14 weeks before the first expected frost, transplanting into the garden when plants have reached 4 to 6 weeks of age.From Seed.How to Grow.Keeping the soil pH above 6.8 will help prevent clubroot, a common cabbage disease that thrives in acidic soil.To prevent splitting, keep plants well-watered.Root pruning is a technique that can help reduce the amount of moisture plants can absorb, preventing splitting.Read more about preventing heads from splitting here.Use season extension tools such as row covers to get an early start in spring and/or keep plants growing later into the fall.Always rotate crops to retain soil fertility and reduce risk of disease.Don’t plant cabbage near other brassicas, they will attract the same pests and diseases.These very common and sneaky little pests can appear at any time during the growing season and can quickly munch their way through the leaves, leaving plants damaged and weak.Adults are gray-brown moths, which deposit small green eggs on plants that hatch as destructive larvae in only a few days.Flea beetles are small jumping insects that chew small holes in leaves.Flea beetles can also transmit diseases to plants, so it is doubly important to keep infestations under control.Practice crop rotation to reduce the risk of continued infestation.Disease.Though disease can appear in many conditions, too much moisture and low soil pH may increase risk of infection.Another common brassica infecting fungus, this disease causes dark spots on stems and leaves.Avoid planting infected seeds, remove infected plants, and remove and destroy crop debris after harvest.Choose disease resistant varities, rotate crops regularly, and remove all parts of cabbage plants from the garden after harvest to prevent diseases and pests from lingering in the soil.Read more about black rot prevention and control.Harvesting.Time to harvest can vary with variety and can range anywhere from 2 to 5 months from seeding.It may be possible to get a second harvest of an early variety.If you leave the outer leaves and roots intact when doing the initial harvest, the plant will send up several new heads.Tip: if you harvest the full plant, store roots in root cellar through the winter, and replant them in spring after a thaw.Plant Type: Biennial grown as an annual Water Needs: 1.5 inches per week Native To: Europe Maintenance: Moderate Hardiness (USDA Zone): 1-10, depending on type Soil Type: Nutrient rich Season: Spring and fall Soil pH: 6.5-6.8 Exposure: Full sun Soil Drainage: Well draining Time to Maturity: 30-60 days Companion Planting: Aromatic herbs, onions, garlic, beets, celery Spacing: 12-18 inches Avoid Planting With: Strawberries, tomatoes Planting Depth: 1/4-1/2 inch Family: Brassicaceae Height: 12-14 inches Genus: Brassica Spread: 18-24 inches Species: B. oleracea Tolerance: Salt, frost, heavy lime Cultivar group Capitata Pests & Diseases: Caterpillars, cabbage loopers, sawflies, aphids, cutworms, root maggots, whiteflies, flea beetles, white spot/leaf spot, black rot, downy mildew, clubroot, blackleg.Cabbage is nutritious and really a garden must have.
Growing a Healthy Cabbage – Bonnie Plants Cabbage Program
To keep your cabbage growing and healthy, you’ll need to take care of it properly.Once your cabbage is planted:.Water wisely: It’s best to water in the morning and at the base of the plant (soil level) keeping the foliage dry.Plants should be watered when the top 2 inches of the soil becomes dry to the touch. .
How to Grow Cabbage
Cabbage is another member of the Brassica family that is full of nutrients, including vitamins A, B1, B2, and C, as well as various antioxidants.Sow indoors beginning in late winter and transplant outdoors from 2 weeks after the last frost date to early summer.When learning how to grow cabbage, sow 3 or 4 seeds per pot, 5mm (¼”) deep, under very bright light.Mix ½ cup complete organic fertilizer into the soil beneath each transplant.If growth slows, side dress with a little more balanced organic fertilizer.Heads of early varieties can split from over-maturity, rapid growth after heavy rain, or irrigation after dry spells.If cabbages won’t form heads, it may be from an imbalance of too much nitrogen in the soil in relation to phosphorus.Cabbage heads are ready when they’re firm to the touch, and when the interior is fairly dense.Rapid growth due to excess watering and fertility will also cause splitting of the head.Purple blotch (Alternaria porri) – Avoid wetting foliage if possible.Water early in the day so plant parts above the ground dry as quickly as possible.Pull weeds around plants and garden area to increase air circulation.Purchase healthy transplants or start seed in sterile potting mix or fresh ground.Flea Beetles – Use row covers to help protect plants from early damage.Check for evidence of natural enemies such as gray-brown or bloated parasitized aphids and the presence of alligator-like larvae of lady beetles and lacewings.These plants in the Solanum group thrive in slightly acidic soil, as does the fungus that causes clubroot. .
oleracea), and belongs to the "cole crops" or brassicas, meaning it is closely related to broccoli and cauliflower (var.Under conditions of long sunny days, such as those found at high northern latitudes in summer, cabbages can grow quite large.They can be prepared many different ways for eating; they can be pickled, fermented (for dishes such as sauerkraut), steamed, stewed, sautéed, braised, or eaten raw. A related species, Brassica rapa, is commonly named Chinese, napa or celery cabbage, and has many of the same uses.The original family name of brassicas was Cruciferae, which derived from the flower petal pattern thought by medieval Europeans to resemble a crucifix. Many European and Asiatic names for cabbage are derived from the Celto-Slavic root cap or kap, meaning "head".The cabbage inflorescence , which appears in the plant's second year of growth, features white or yellow flowers, each with four perpendicularly arranged petals.The inflorescence is an unbranched and indeterminate terminal raceme measuring 50–100 cm (20–40 in) tall, with flowers that are yellow or white.Each flower has four petals set in a perpendicular pattern, as well as four sepals, six stamens, and a superior ovary that is two-celled and contains a single stigma and style.The fruit is a silique that opens at maturity through dehiscence to reveal brown or black seeds that are small and round in shape.Leaf types are generally divided between crinkled-leaf, loose-head savoys and smooth-leaf firm-head cabbages, while the color spectrum includes white and a range of greens and purples.Cabbage has been selectively bred for head weight and morphological characteristics, frost hardiness, fast growth and storage ability.The appearance of the cabbage head has been given importance in selective breeding, with varieties being chosen for shape, color, firmness and other physical characteristics. Breeding objectives are now focused on increasing resistance to various insects and diseases and improving the nutritional content of cabbage.Although cabbage has an extensive history, it is difficult to trace its exact origins owing to the many varieties of leafy greens classified as "brassicas". A possible wild ancestor of cabbage, Brassica oleracea, originally found in Britain and continental Europe, is tolerant of salt but not encroachment by other plants and consequently inhabits rocky cliffs in cool damp coastal habitats, retaining water and nutrients in its slightly thickened, turgid leaves.However, genetic analysis is consistent with feral origin of this population, deriving from plants escaped from field and gardens.Because of the wide range of crops developed from the wild B. oleracea, multiple broadly contemporaneous domestications of cabbage may have occurred throughout Europe.Nonheading cabbages and kale were probably the first to be domesticated, before 1000 BC, perhaps by the Celts of central and western Europe, although recent linguistic and genetic evidence enforces a Mediterranean origin of cultivated brassicas.While unidentified brassicas were part of the highly conservative unchanging Mesopotamian garden repertory, it is believed that the ancient Egyptians did not cultivate cabbage, which is not native to the Nile valley, though the word shaw't in Papyrus Harris of the time of Ramesses III has been interpreted as "cabbage". Ptolemaic Egyptians knew the cole crops as gramb, under the influence of Greek krambe, which had been a familiar plant to the Macedonian antecedents of the Ptolemies. By early Roman times, Egyptian artisans and children were eating cabbage and turnips among a wide variety of other vegetables and pulses. The more traditionalist Cato the Elder, espousing a simple Republican life, ate his cabbage cooked or raw and dressed with vinegar; he said it surpassed all other vegetables, and approvingly distinguished three varieties; he also gave directions for its medicinal use, which extended to the cabbage-eater's urine, in which infants might be rinsed.According to Pliny, the Pompeii cabbage, which could not stand cold, is "taller, and has a thick stock near the root, but grows thicker between the leaves, these being scantier and narrower, but their tenderness is a valuable quality".The Greeks and Romans claimed medicinal usages for their cabbage varieties that included relief from gout, headaches and the symptoms of poisonous mushroom ingestion.At the end of Antiquity cabbage is mentioned in De observatione ciborum ("On the Observance of Foods") by Anthimus, a Greek doctor at the court of Theodoric the Great.Cabbage appears among vegetables directed to be cultivated in the Capitulare de villis, composed in 771–800 AD, that guided the governance of the royal estates of Charlemagne. French naturalist Jean Ruel made what is considered the first explicit mention of head cabbage in his 1536 botanical treatise De Natura Stirpium, referring to it as capucos coles ("head-coles"). In India, cabbage was one of several vegetable crops introduced by colonizing traders from Portugal, who established trade routes from the 14th to 17th centuries. Sauerkraut was used by Dutch, Scandinavian and German sailors to prevent scurvy during long ship voyages.Jacques Cartier first brought cabbage to the Americas in 1541–42, and it was probably planted by the early English colonists, despite the lack of written evidence of its existence there until the mid-17th century.Cabbage is generally grown for its densely leaved heads, produced during the first year of its biennial cycle.Plants are generally started in protected locations early in the growing season before being transplanted outside, although some are seeded directly into the ground from which they will be harvested. Seedlings typically emerge in about 4–6 days from seeds planted 13 mm (1⁄2 in) deep at a soil temperature between 20 and 30 °C (68 and 86 °F). Closer spacing reduces the resources available to each plant (especially the amount of light) and increases the time taken to reach maturity.When being grown for seed, cabbages must be isolated from other B.
oleracea subspecies, including the wild varieties, by 0.8 to 1.6 km (1⁄2 to 1 mi) to prevent cross-pollination.Fungal diseases include wirestem, which causes weak or dying transplants; Fusarium yellows, which result in stunted and twisted plants with yellow leaves; and blackleg (see Leptosphaeria maculans), which leads to sunken areas on stems and gray-brown spotted leaves. The fungi Alternaria brassicae and A. brassicicola cause dark leaf spots in affected plants.They are both seedborne and airborne, and typically propagate from spores in infected plant debris left on the soil surface for up to twelve weeks after harvest.Rhizoctonia solani causes the post-emergence disease wirestem, resulting in killed seedlings ("damping-off"), root rot or stunted growth and smaller heads.Clubroot, caused by the soilborne slime mold-like organism Plasmodiophora brassicae, results in swollen, club-like roots. The cabbage looper (Trichoplusia ni) is infamous in North America for its voracious appetite and for producing frass that contaminates plants.Factors that contribute to reduced head weight include: growth in the compacted soils that result from no-till farming practices, drought, waterlogging, insect and disease incidence, and shading and nutrient stress caused by weeds.Vacuum cooling rapidly refrigerates the vegetable, allowing for earlier shipping and a fresher product.The simplest options include eating the vegetable raw or steaming it, though many cuisines pickle, stew, sautée or braise cabbage.It is frequently eaten, either cooked or as sauerkraut, as a side dish or as an ingredient in such dishes as bigos (cabbage, sauerkraut, meat, and wild mushrooms, among other ingredients) gołąbki (stuffed cabbage) and pierogi (filled dumplings).Other eastern European countries, such as Hungary and Romania, also have traditional dishes that feature cabbage as a main ingredient. Cabbage is also a moderate source (10–19% DV) of vitamin B6 and folate, with no other nutrients having significant content per 100-gram serving (table).The Ancient Greeks recommended consuming the vegetable as a laxative, and used cabbage juice as an antidote for mushroom poisoning, for eye salves, and for liniments for bruises. Ancient Egyptians ate cooked cabbage at the beginning of meals to reduce the intoxicating effects of wine.The cooling properties of the leaves were used in Britain as a treatment for trench foot in World War I, and as compresses for ulcers and breast abscesses.The latter toxin has been traced to pre-made, packaged coleslaw mixes, while the spores were found on whole cabbages that were otherwise acceptable in appearance.Biological risk assessments have concluded that there is the potential for further outbreaks linked to uncooked cabbage, due to contamination at many stages of the growing, harvesting and packaging processes.Contaminants from water, humans, animals and soil have the potential to be transferred to cabbage, and from there to the end consumer.Cabbage and other cruciferous vegetables contain small amounts of thiocyanate, a compound associated with goiter formation when iodine intake is deficient.Studies done in Kitui County, Kenya, That Cabbages are due to their Nitrate Content, poisoness if consumed. .
How to grow cabbages / RHS Gardening
Cabbages can be sown either directly in the ground outside or in modular trays (and left outdoors).If you only want a few cabbages or have limited space, it’s easiest to sow in trays (one seed per module), then transplant outdoors later.Traditionally, cabbages are sown into a ‘seed bed’ – a site away from the main vegetable plot – then transplanted later in the season.This is because sowing them at their final spacing in your main plot would take up a lot of room early in the season, when you could be using it for fast-maturing crops such as lettuces.Summer cabbages: sow from late February/early March (under cloches or similar cover) until early May; transplant in May/June.If possible, prepare the ground in autumn by adding plenty of well-rotted manure or garden compost, then leave it over winter to consolidate.When your young cabbage plants have five or six true leaves, it’s time to transplant them to their final growing position.White larvae approximately 5cm (2in) long, feed on the roots just below the soil surface, stunting growth and causing plants to wilt and die.These feed on the young seedlings and you'll see the tell tale slime trail on the soil around your crop, as well as on the leaves.There are many ways to control slugs and snails, including beer traps, sawdust or eggshell barriers, copper tape and biocontrols.Sowings of spring, summer and winter varieties can provide cabbages throughout the year.Nigel Slater combines cabbage with garlic, ginger and spring onions in this Thai-style brassica stir-fry.varieties for autumn & winter cropping 'Advantage' AGM A versatile cabbage that can produce throughout the year.'Duncan' AGM A spring cabbage that produces a plentiful crop of small, pointed mid-green heads.Very good quality with large, heavy heads and sweet, crisp, white hearts.It has solid, dense heads with characteristic red tinged outer leaves. .
Ornamental Cabbage or Kale: Plant Care & Growing Guide
Botanical Name Brassica oleracea Common Name Ornamental cabbage, ornamental kale Plant Type Annual or biennial Mature Size 12–18 inches tall and wide Sun Exposure Full sun Soil Type Rich loam, medium moisture, well-draining Soil pH 5.5 to 6.5 (slightly acidic) Bloom Time Rarely flowers Flower Color Insignificant Hardiness Zones 2–11 Native Area Southern and Western Europe.Ornamental cabbage and kale look especially good in a large grouping or as edging for a garden bed, where their purplish hues blend well with other fall colors.These are cool-season plants that are usually grown in the fall or early spring, discarded as the weather turns very cold or as the warm summer months arrive.Ornamental cabbage and kale don't develop their full colors unless they get a good chill from a frost.But if the weather is damp and the plants don't have good air circulation, they might develop fungal diseases, which can appear as spots on the leaves.'Chidori' ornamental kale: This plant has very curly leaf edges with leaves that are purple, creamy white, or deep magenta.This plant has very curly leaf edges with leaves that are purple, creamy white, or deep magenta.'Color Up' ornamental cabbage: This grows upright with green leaves and centers of white, pink, or fuchsia.This ornamental cabbage has large, smooth leaves with center colors of pink, red, or white.This plant looks more like its edible kale cousins, with loose growth and deeply serrated leaves in red, purple, or white.'Pigeon' series ornamental cabbage: This variety has a flattened shape with red or white centers.For spring plants, cabbage or kale seeds should be started indoors about eight weeks before the last expected frost date.Plant the seeds about 1/4 inch deep and keep the soil moist in a bright location at about 70 degrees Fahrenheit.Common disease problems include leaf spots, blackleg, black rot, and yellows. .
Native Plant: Eastern Skunk Cabbage
What native Wisconsin plant is the first to bloom in the spring, generates its own heat capable of thawing frozen soil and melting snow, and produces flowers before leaves; flowers that emit a smell of rotting flesh?Skunk cabbage (Symplocarpus foetidus) flowers emerge from the ground in early spring before the leaves.The plants can produce temperatures of 15-35 degrees C (55-95 F) allowing them to grow through frozen ground.The heat may also help them spread the odor of their flowers and attract early spring pollinators which come to eat and take refuge in the flower structure.The "flowers" actually consist of a spathe and a spadix.After being pollinated the flowers produce a large 10cm (4inch) tall by 1cm (1/3 inch) wide, purple or black, compound fruit which ripens as or soon after the rest of the plant has gone dormant.Range.Eastern skunk cabbage is a boreal species found in both North America and Asia.Eastern skunk cabbage grows in wet mucky soil, along streams or springs, in woods, thickets, and bogs.It is a conservative species that does not bounce back from deforestation or changes in water levels that often accompany agriculture and development. .
