How to grow tree collards


Learn - Project Tree Collard

While it is relatively easy to start tree collards from cuttings it takes a few minutes of DAILY attention until the plants have rooted. They are usually sold in bundles of 3 or 4 cuttings because often not all cuttings will make it. Some customers are unable to successfully root any of them.  For this reason, we do NOT recommend that beginner gardeners buy cuttings because it may be easier to start with a rooted plant.  Once the plant is a 3-4 months old, the beginner gardener can try their hand at rooting their own cuttings from their own plant. This mitigates the financial risk. We have a complete tutorial on how to propagate tree collards from cuttings below. Starting tree collards from cuttings usually requires daily watering and/or daily moisture checks, which is a similar commitment one needs to grow plants successfully from seed. It is important to not overwater them, while still keeping them moist enough to root. Depending on the time of year and climate, it can take anywhere from 4 to 8 weeks. In temperate climates that rarely freeze or get hot, cuttings will root easily all year. However, cuttings do not root well in the coldest nor the warmest months in areas with 4 seasons. In these areas, it is best to order cuttings in spring or fall when temperatures are in the 50s to 70s.

If you order tree collard cuttings in the mail, we recommend our simple directions included to help make sure that your collards get off to a great start. It requires only potting soil, containers, and cuttings and is the same way we propagate our plants for sale. You may find other information/techniques for rooting including: water cloning machines, using rooting hormones, and rooting in water. While these may work sometimes, we have not found these methods to work as consistently. Even one happy plant can get you started and you can take more cuttings of it once it has taken off.

The basic steps for rooting a tree collard are: take a cutting, plant it in a container with potting soil, keep the soil moist in appropriate lighting, and wait patiently for your new plant to grow. Below is an updated video we made in 2020 on propagating tree collards from cuttings, followed by a more detailed written explanation.

Take a Cutting

You want to take your cuttings from fresh growth on the tips of an existing tree collard, making sure they are four to six inches long. The cut on the bottom should be cut at an angle. Next, cut off all of the leaves, except for 2-3 tiny ones on the very top of the cutting. Leaves respire a fair amount of water so you need to remove them. It is fine if a cutting isn’t particularly straight as tree collards eventually get curly growth. The diameter of the cutting should be at least as wide as a pencil. Wider cuttings usually take off more quickly, but not always.

Plant cutting in a container with potting soil

We suggest using a second hand 4 inch or one gallon sized nursery container. If you don’t have one, an alternative is to create 4-5 quarter inch holes in the bottom of a quart yogurt container or something similar. Holes on the bottom are critical for proper drainage or the cutting may rot.

Fill the container with a high quality potting soil. We have used “Recipe 420” potting soil by EB Stone and Happy Frog Potting Soil by Foxfarm, but any organic and natural potting soil available in your area will be a good choice. A good potting soil will hold on to a lot of water but will still drain well. If you don’t have access to potting soil, you can also use perlite, vermiculite, and all purpose sand mixed with some compost. Garden soil on the other hand can be very ‘heavy’ and not drain very well in a nursery can but if you don’t have any other options, try using garden soil that is very high in organic matter (for example, collect soil from under a pile of rotting branches and leaves).

Tap your container with the potting soil down on a hard surface to help it settle. Then stick the cutting two thirds or even further in your soil. Gently press your fingers or fist down around the cutting. Now it is time to water it.

Keep the cuttings moist but not waterlogged. Depending on the temperature and sun exposure, you will likely need to water the cuttings daily.

During a warm time of year you’ll want to keep your cuttings in containers somewhere semi-shady that is protected from full sun. They do need some sun daily, so dappled or filtered sun is good. Morning sun is less intense than afternoon sun.  During cooler months, shade isn’t critical, in fact your plant will root faster in the sun as long as it doesn’t get too hot and dry out. Tree collards can tolerate some freezing weather once established, but it is best to protect your cuttings from hard freezes until they have roots and are planted in the ground. In warm times of year you’ll want to water the cuttings at least once a day. Again, it is best to root cuttings in temperatures of 50s to 70s.

Have patience

Besides keeping the soil around the cuttings moist, you should leave them alone. Don’t pull them out to check for roots. They might be there and you might accidentally break them off when you’re trying to check on them. Wait for the tree collards to start growing new leaves. Once your tree collard plant have a fair amount of new growth and you can perhaps see a couple roots poking out your pot’s drainage holes, you’ll know it’s time to plant it in the garden. Four to six weeks is a fairly common wait time, though it can take longer.

Growing Tree Collards in Containers and in the Garden

Tree Collards Are a Perennial Longevity Plant

We’re really getting into growing perennial vegetables, and more recently we’re growing tree collards in containers and also in raised garden beds. We started with purple tree collards and expanded into green tree collards as well.

Standing tall among their fellow perennial vegetables, tree collards are the most prolific and longest lasting member of the brassicas.

Common Names for Tree Collards

  • Purple Collards
  • Tree Kale
  • Walking Stick Kale

Scientific Name for Tree Collards

  • Brassica oleracea var. Acephala

Brassica is latin for cabbage (Brassica oleracea capitata), which is in the mustard family.

Tree Collards Grow Zones

You’ll find mixed information on tree collard grow zones. The reason for this may be — in part — due to different strains of tree collards.

We originally got our cold-hardy purple tree collards from Oikos Tree Crops owned by horticulturist, Ken Asmus in Michigan. His cold hardy strains bred from seeds could withstand Michigan winters.

Unfortunately, Ken has since closed his nursery after 40 years, so you can’t currently buy his cold-hard strain of tree collards. However Ken does plan to continue growing and developing new strains as part of his lifelong work on his farm, with more options for the public over time.

In the meantime, the same type of hardy tree collards has been made available for order by the folks at Project Tree Collard.

Most tree collards do best in growing zones 7-10.

How Many Years Do Tree Collards Live?

A perennial leafy vegetable, tree collards live an average of eight years.

You’ll find different numbers on longevity spinach growing zones and lifespan online. When dealing with lesser known plants and different strains of plants growing in various climates, and growing conditions the numbers ranging between 5 and 15 years.

Tree collards — Brassica oleracea var. Acephala — are the most prolific and longest lasting member of the brassicas, at 10 years on average.

What Do Tree Collards Taste Like?

Tree collards offer gardeners an easy to grow vegetable with luscious tasting green or purple leaves that mimic the flavor of kale. Many gardeners say they prefer the taste of the Purple Tree Collards over the green type, and they also add additional color interest in the garden, so we’re starting with growing purple tree collards.

The amazing plants can grow up to 6 feet tall, and with proper support, even taller with a tree-mendous spread of 6 to 8 feet. Tree collard plants can flourish for as many as 8-10 years! That’s a lot of healthy leaf production for year round food source. Brassica oleracea var. Acephala is a wonderful addition to the vegetable garden or edible landscape or foodscape.

Tree collards taste like a cross between kale, chard and collards.

Challenges Growing Tree Collards

While tree collards are often touted as an easy perennial vegetable to grow, there are definitely challenges. They’re not fussy growers when it comes to soil and sun and they tend to grow well in sun or partial shade.

So given all these positive attributes of longevity, high nutrition and easy growing in varied light and soil, what are some of the problems in growing green and purple tree collards? What’s the catch and why aren’t more people growing them?

Actually there are a few. While Brassica vegetables are often touted as hardy, that’s not the case with these tall plants that originated from the balmy climes of North Africa.

Moderately Cold Hardy to Above 20°F / 6.67°C

The main vulnerability of growing tree collards is plant hardiness as they cannot tolerate winter temperatures below 20°F / 6.67℃. The perennial plants need a protected spot even in USDA Zone 8, where microclimates maintain the coldest temps above the 20°F mark.

A nursery grower in Michigan has been hybridizing Purple Tree Collards toward enhanced hardiness. Results have produced plants that have survived -17°F temperatures in an unheated poly-house. According to Oikos Tree Crops, these extra hardy Purple Tree Collard leaves taste just as delicious as the original tender type.

However, as indicated earlier in this article, Ken Asmus isn’t currently selling them from his nursery in Michigan.

Tree Collards Pest and Disease Issues

Unfortunately, these “walking stick kale” plants are not pest resistant. While we haven’t had issues with disease, we have had three out of five plants destroyed by pests that commonly afflict cabbage and other brassicas, such as cabbage worms and slugs.

We Lost 60% of our Tree Collards to These Pests
  • Slugs
  • Cabbage worms
  • Voles

To help get rid of garden slugs we used Sluggo Plus. For the cabbage worms we applied BT (bacillus thuringiensis) or Dipel, which you can buy from your local hardware or home store, and also on Amazon. We have some tips to get rid of voles and moles, but it’s a harder battle.

Propagating Purple Tree Collards

Purple Tree Collards are difficult to propagate from seed, so growing tree collards by rooting cuttings from a parent plant is much better. Apparently, this is the way most Purple Tree Collards are passed along from grower to grower.

We ordered Purple Tree Collards cuttings from Healthy Harvesters via Etsy. 8 inch healthy cuttings were pruned at the bottom with a sharp knife, the bottom section dipped in . 2 percent IBA hormone powder, and grown in preferred mixture of potted medium. We use Black Gold organic potting soil.

Warming mats are useful for keeping plant cuttings at an optimum temperature range of 60-70°.

Cultivating Purple Tree Collards

Like many other brassicas, tree collards do well in full sun and dappled shade, in rich (organic) soil with only slight acidity, and consistent irrigation. Tree collards grow tall, and If left unstaked, will tumble and sprawl so staking and pruning are necessary.  

Tree Collards meet the general definition of perennial food plants in warmer climes and as “tender” perennials that can be nurtured and protected during the winters in colder zones. Our Longevity Spinach (Gynura procumbens) are tender perennials currently snowbirding in our green house.

Tree Collards Size

  • 5-10 feet tall
  • 5-10 feet wide

Can grow to 4-6′ in one season; can be pruned into bush form or staked to grow tall.

Growing Tree Collards in Containers

Individual tree collards grow well in containers, which offers the advantage of taking them indoors for the winter. So if you’re growing tree collards in a colder climate, you might want to start out with them in pots.

Another tactic would be to treat them as an annual crop. You can take cuttings to root indoors and set the new plants back out in spring.

We’re started growing tree collards in containers so that we can move them outside in spring through fall. Come winter temps below freezing, we’ll bring them indoors to our sunroom or else into our cattle panel greenhouse. We’ll probably end up with a large pot in both places, that way we can easily harvest leaves for daily use to add into most meals.

Once we get our first-year Purple Tree Collards going as container plants, they’ll be taken inside the greenhouse for the winter and set out the next spring. If they’re thriving inside, we’ll definitely continue harvesting leaves from them throughout the winter. If they grow slow or dormant, we’ll just pluck a leaf a day like chewable vitamins like we do with our longevity spinach. 😎🍃

Staking Tree Collards in Containers

As tree collards grow taller, they typically need staking. You could grow your tree collards in planters with a built in climbing trellis, or against a wall with a trellis. Growing vertically works best in locations with limited sunlit space.

Pruning Tree Collards

When growing tree collards in containers it’s best to prune them from getting so tall, in which case you may not need to stake them. Pruning the height should help them bush out and become fuller rather than taller and leggy.

You can also prune your tree collards into the shape you’d prefer and dependent on whether you have more vertical or horizontal space to work with. When growing them taller, you can use tomato cages for staking in pots, or a teepee stakes made from bamboo or wood.

Where to Buy Tree Collard Plants

  • Project Tree Collard
  • Etsy
  • Amazon
  • Oikos Tree Crops – nursery is closed by may still have helpful information

We’re also testing the Purple Tree Collard hybrids from Oikos Tree Crops. Time will tell how these hybrids perform in our Zone 7A gardens. So we’ll be back here with updates.

UPDATE: So far our purple collards are holding up to zone 7a weather. However, our greatest challenge has been pests, so we’re stepping up our treatments accordingly.

Growing Perennial Vegetables

We’re eagerly increasing the number of perennial vegetables we’re growing. It just makes so much sense toward food security and return on investment. A good book we’re enjoying is: Perennial Vegetables by Eric Toensmeier, which includes a section on tree collards.

Are any of you growing tree collards (green or purple)? We’d be glad to hear about your experience, and see any photos you care to share.

If you’re interested in tree collards you will likely also be interested in longevity spinach, Gynura procumbens.

    Characteristics of culture

    Cabbage is a cold-resistant, photophilous plant that needs a lot of moisture. The peculiarity of the culture is its unpretentiousness to the composition of the soil, however, it needs regular complex feeding with nutrients. A good harvest cannot be achieved without fertilizers containing nitrogen, phosphorus and potassium.

    Growing cabbage from seeds

    Sowing seeds and properly growing seedlings is the key to strong and healthy plants. Let's figure out how to plant cabbage.

    Sowing

    Sowing seeds begins with calibration - rejection of small and weak seeds. To do this, all the seeds are placed in lightly salted water for 15–20 minutes. The floating seeds are discarded. The rest are dipped in a 1% solution of potassium permanganate to disinfect. After that, the seeds are laid out on a damp cloth, sprayed with any growth stimulant and left to swell for three to four days. Also at this stage, it is recommended to remove the seeds overnight in the refrigerator. This procedure is called hardening and helps the plants become stronger.

    Cultivation of seedlings of cabbage

    Cabbage seeds are planted in moist, but not wet soil to a depth of 2-3 cm. Subsequently, the soil is regularly watered, preventing waterlogging and drying out. The most important thing at this stage is to maintain the temperature regime and monitor the duration of daylight hours.

    Optimum temperature:

    • for seedlings - +20 °C;
    • for seedlings in the first week - +10 °C during the day, +8 °C at night;
    • for sprouts - up to +17 °C during the day, +10 °C at night

    Picking seedlings

    How to grow good cabbage in the open field? Remember a small but important secret: the cabbage root system does not like to be disturbed. The sooner the picking of the sprouts occurs, the better they will take root during planting. The best time is immediately after the appearance of two true leaves.

    Planting cabbage in open ground

    Prepare seedlings for harsh summer conditions: feed with fertilizers and send the pots to the balcony in a couple of weeks so that the young shoots get used to temperature changes and are not capricious in the beds.

    When to plant

    The planting time for cabbage depends on its variety. Early cabbage is planted from the end of April to the May holidays, late varieties - from the beginning of May to the end of the second decade. The sooner the plants are planted, the faster the leaves will begin to grow and the more powerful the root system will be. In the middle lane, including in the Moscow region, cabbage planting dates fall at the beginning of May, after a steady warming.

    Suitable soil

    The plant grows well in all but clay and peaty soils. Cabbage is very fond of “tasty food”, so prepare beds for it on the sunny side in advance. Acidic soil must be alkalized with lime. Add 6–7 kg of humus, superphosphates and potassium chloride (1–2 tablespoons each) per square meter of beds.

    Planting rules

    To calculate the required amount of space for plants and understand at what distance to plant cabbage, use the following diagrams:

    • early-ripening varieties are planted in open ground at a distance of 30x30 cm;
    • mid-season plants are planted according to the scheme 45x45 cm;
    • late varieties grow stronger and require a minimum distance of 60x60 cm between plants.

    Beginner gardeners will find this guide explaining how to plant cabbage step by step:

    1. Prepare wells and flush with plenty of water.
    2. Place a handful of ashes in each hole.
    3. Remove seedlings with a clod of earth and place them in the ground, falling asleep under the first leaves.
    4. If the weather is clear, cover the plants with hoods to protect them from the sun for a couple of days.

    Caring for cabbage

    Planting cabbage in the country is not difficult, but getting a good harvest is not an easy task. Proper cultivation and outdoor care of young plants will provide you with strong and tasty cabbage heads by autumn.

    Watering

    Growing any variety of cabbage outdoors, be it white cabbage, Brussels sprout or kohlrabi, is inextricably linked with regular abundant watering. Cabbage loves warm water, so never use the central water supply for irrigation: low temperatures are detrimental to plants. Water the cabbage from a scoop or bucket, as the water from the hose is supplied under high pressure and can harm the root system.

    To water your cabbages less often, use a trick: mulch the soil in the beds with straw or hay. This will save you from regular cabbage care - weeding and loosening the soil. When the heads of cabbage begin to ripen, reduce watering, otherwise they may crack badly.

    Top dressing

    Top dressing is also important when growing cabbages outdoors. When a plant is actively developing, it absorbs nutrients like a sponge.

    Mandatory from the moment of planting until the formation of heads once every one and a half to two weeks, cabbage is fed with potassium at a dosage of 10 g per 1 m2. Complex fertilizers are used with the same regularity.

    Cabbage processing

    Cabbage attracts insects and pests like a magnet. Therefore, caring for cabbage necessarily includes preventive treatments of beds with plants.

    Protective measures are carried out according to the following scheme:

    1. In early spring, cabbage is sprayed against cruciferous fleas and cabbage flies. The first treatment is carried out after disembarkation, the second - a week later.
    2. At the beginning of summer, cabbage should be protected from fleas, cabbage flies and aphids. Spraying is carried out once every two weeks.

    Diseases and pests

    Growing cabbage outdoors is always associated with the danger of diseases and pests. To protect plants from them, you should adhere to the technology of growing cabbage - proper watering, top dressing, enough space and light. This increases the resistance of the plant and helps it to cope with these misfortunes more easily.

    The most common cabbage diseases are bacteriosis, gray and white rot, black leg, phomosis.

    It is better to protect against diseases than to cure. Harden off seeds and seedlings and do not plant cabbage in one place more than once every 3 years.

    Most of all they like to eat cabbage: bugs, aphids, cabbage flies and fleas, leaf beetles, secretive botanists. Insecticides and careful pruning and destruction of all affected leaves will relieve them.

    Harvesting and storing cabbages

    Harvest cabbages when the cabbages are firm and springy to the touch. Early cabbage is harvested without stalks in order to grow a second crop from them. The later one is pulled out entirely.

    Heads are stored at temperatures down to -1 °C, without removing the top sheets, on wooden shelves. It is best to lay out the cabbage next to each other, and not to store in a pile.

    Popular types and varieties of cabbage

    When choosing a variety for growing cabbage, we recommend paying attention to the following types:

  8. mid-season: "Belarus", "Nadezhda", "Slava".
  9. later: Amager, Krumont, Extra.
  10. cultivation, planting, care in the open field

    Before you start growing cabbage, you need to decide what you need it for. If you are going to use it in the summer for salads, cabbage soup and pies, then you need to choose early varieties. For fermentation and twists, mid-ripening ones are ideal. But only late varieties are suitable for winter storage.

    Cultivation of cabbage

    White cabbage can be grown from seedlings, but this is a troublesome task. Cabbage is a cold-resistant plant, so in most regions of Russia it can be sown immediately in open ground.

    It is useful to pre-soak the seeds for a day in warm water, and then wrap them in a damp cloth. As soon as they hatch, the fabric must be unfolded, put together with the seeds in a plastic container and sent for a week in the refrigerator. And then get it, stand for a day in a warm room and only then sow.

    Such hardening will help increase the resistance of seedlings to spring frosts. Yes, they can already easily tolerate a drop in temperature to -5 ° C (1), but after a week in the refrigerator they will also withstand more serious cold snaps.

    Planting cabbage

    The place for cabbage should be chosen taking into account the predecessors. It is best to sow it after potatoes, cucumbers, carrots, onions, garlic or legumes - peas and beans (2). And in no case should it be planted after radish, radish, turnip and swede - they are all from the same Cruciferous family, they have common diseases and pests.

    If the spring is early and warm, cabbage seeds can be sown already in mid-April. If the spring is long and cold, then at the end of the month.

    - It is better to sow them in holes with a diameter of 50 cm. In each - 3 seeds at a distance of 10 cm from each other and at a depth of 1 cm, advises agronomist-breeder Svetlana Mikhailova. - Beforehand, it is useful to add 1 bucket of humus to each well. After sowing, it is useful to powder the holes with ash - it will protect the seedlings from diseases.

    When the seedlings have their first true leaf, they need to be pulled through, leaving one of the strongest shoots in each hole. In no case should you leave all three - heads of cabbage in such tightness will not tie.

    Cabbage planting pattern depends on the ripening period of varieties:

    • early – 30 cm in a row, 40 – 50 cm between rows;
    • mid-season - 50 in a row, 50 - 60 cm between rows;
    • late - 60 - 70 cm in a row, 60 - 70 cm between rows (3).

    Outdoor cabbage care

    In order to get a good head harvest, the plants must provide 3 important conditions.

    Watering. White cabbage is one of the most moisture-loving vegetables. It needs to be watered once every 2 weeks, 3-5 liters per 1 sq. m. If the weather is hot and dry, the watering rate is increased to 10 liters per 1 square. m.

    Once a week it is useful for cabbage to take a refreshing shower from a watering can directly over the leaves - 0.5 liters per 1 sq. m.

    - Early and mid-season varieties should be watered immediately before harvesting, says agronomist Svetlana Mikhailova. - Watering late from the beginning of September should be reduced in volume by 2 times, and 20 days before harvesting should be stopped altogether.

    Top dressing. During the summer, white cabbage should be fed 3-4 times (depending on the variety):

    • 3 weeks after germination: mullein infusion (1:10) - 0.5 l per plant;
    • 2 weeks after the first: 1 tbsp. a spoonful of nitrophoska per 10 liters of water - 1 liter per plant;
    • 2 weeks after the second: in 10 liters of mullein infusion (1:10) add 2 tbsp. spoons of double superphosphate and potassium sulfate - 1 liter per plant;
    • 20 days before harvest (for late varieties): 2 tbsp. spoons of potassium sulfate per 10 liters of water - 1 liter per plant.

    The last dressing makes the heads tastier and increases their shelf life.

    Pest protection. The main enemies of white cabbage are caterpillars of white butterfly and cruciferous flea. To destroy them, there are a lot of drugs, but they do not always give the desired effect. The most reliable way is to wrap the heads of cabbage with non-woven fabric and tie it tightly on the stalk so that pests do not have the opportunity to get inside.

    Harvesting cabbage

    Early varieties can be harvested as needed.

    Mid-season varieties are usually harvested at the end of September. They can be immediately chopped and fermented, and if there is no time, put in the refrigerator or cellar. But remember, they do not last long, only 1 - 3 months.

    Don't rush to harvest late varieties. It is important that they stay in the beds for some time at low temperatures, about 0 ° C. Only in this case they will lie for a long time. This weather usually happens in the first half of October.

    – Harvest in dry, clear weather. The air temperature should not be higher than 7 °C (if it is warmer outside, the heads of cabbage will not lie for a long time), - explains agronomist Svetlana Mikhailova. - You need to cut them so that a stump about 3 cm long remains. Cut cabbage should be put away in the cellar or refrigerator as soon as possible - in the open air without roots, it quickly withers and then is stored worse.

    Carrying and storing heads of cabbage should be done carefully so as not to damage the protective leaves, because every wound is a gateway for infection. It makes no sense to clean cracked heads of cabbage in the cellar - they will rot very quickly. They must be eaten as soon as possible.

    Cabbage storage rules

    Optimal cabbage storage conditions are as follows:

    • temperature - 0 - 1 °С;
    • air humidity - 95%.

    Higher temperatures reduce the shelf life of cabbage. And at 4 ° C, heads of cabbage begin to germinate.

    The varieties stored the longest are: Amager 611, Belorusskaya 445, Zimovka 1474, Gift (4).

    Popular Questions and Answers

    We talked about growing cabbage with agronomist-breeder Svetlana Mikhailova.

    Should cabbage seeds be soaked before sowing?

    Cabbage seeds do not need to be soaked - wet ones are more difficult to sow, and they germinate well even when dry. Moreover, cabbage is sown in the second half of April, and at this time the ground is still wet.

    Should cabbage seeds be germinated before sowing?

    Seeds are germinated so that they quickly take roots in deeper layers of the soil - this is important when sowing is done at the end of May. At this time it is already warm, and the soil dries out very quickly. A bush is sown in April, when there is a lot of moisture. So there is no need to germinate cabbage seeds. Moreover, they are small and it will be extremely difficult to sow from roots.

    Should I mulch the soil under the cabbage?

    This will be a huge plus! Cabbage consumes a lot of water, and moisture from the soil evaporates strongly in summer, when it is hot. As a result, plants suffer from drought.
