Walking Stick Kale – a Tall Kale for Talking

Walking stick kale is also known as Jersey kale and walking stick cabbage, but, formally, it’s known as Brassica oleracea var. longata. Tree kale; which is also known as walking stick kale, tree cabbage, and tree collard, among other similar names; is formally known as Brassica oleracea var. acephala. So, while all varieties of kale are closely related, these two are different but similar strains.

A Walking Stick Kale History

Walking stick kale comes from the island of Jersey, which is the largest of the Channel Islands. These islands are in the English Channel off of the northern coast of France. The leaves, which grow in a tuft at the top of the stalk, were used to feed the sheep and cows that were raised on the island. Five of the plants could feed 100 sheep or 10 cows.

Walking stick kale generally grows to a height of 8 to 10 feet, but it can reach 18 to 20 feet. The tuft of leaves at the top make the plants top heavy, and, if not staked, the stalks tend to bend over, creating a naturally-grown cane handle at the root end. Cane handles were also formed by heat-treating the stalk and then bending it at the root end. The stalks harden as they dry, and they are then lightly sanded and varnished. By the early 1800s, 30,000 walking sticks a year were being sold. Waking stick kale was also used as rafters in buildings and as fencing.

Growing Walking Stick Kale

Seeds for walking stick kale are difficult to find, and even if you find them, like the seeds for tree kale, they may not grow true to the walking stick variety. So, it might be best to grow walking stick kale from cuttings, as you would tree kale.

Whether you start your walking stick kale from seeds or cuttings or indoors or outdoors, growing it is a bit different from growing garden kale or even tree kale. You should:

  • Plant or thin your seedlings so that they have 40 inches of growing space each.
  • Give your plants 2 inches of water each after planting or transplanting them, and then give them 2 inches of water each, each week.
  • Feed them with an organic fertilizer every three weeks.

Walking stick kale grows as a mostly bare stalk with the tuft of leaves at the top rather than branching out as tree kale does, so pruning it as you would tree kale probably will not encourage branching.

Choosing a Location for Walking Stick Kale

Walking stick kale prefers the same growing conditions as other kales. Choose as spot that with well-drained, loamy or sandy soil that receives full to partial sun. Like tree kale, though, walking stick kale is a perennial that can live for up to at least three years. It’s more likely to live longer in more temperate climate zones.

Walking Stick Kale and Kale Pests

Because walking stick kale grows so tall so quickly, it is less bothered by kale pests than even tree kale is.

Staking Walking Stick Kale

Just because the leaves of walking stick kale were once used to feed sheep and cows doesn’t mean they won’t taste good to humans. The leaves of walking stick kale can be used in the kitchen the same way that the leaves of tree kale are used. Try them in stews, soups, and stir fries, and, given their size, these leaves should make wraps large enough to please even the hungriest person in the crowd.

So, if you want to grow your walking stick kale to eat and you aren’t interested in experimenting with growing a walking stick, then stake your walking stick kale as you would tree kale. To grow walking stick kale with a ready-made hook, you will need to stake it a little differently.

Growing Walking Stick Kale as a Walking Stick

If you want to shape your walking stick kale to form a handle as it grows, you should transplant it about one week before the first frost date in your area. That means you should start your seeds five to six weeks before that date. You should start cuttings about eight weeks before that date.

Nine plants should produce eight usable walking sticks, but only one is likely to be perfect.

When encouraging walking stick kale to form a hook in the stalk, you will need a either a 6 foot long 2 inch x 2 inch stake or a 1 inch in diameter metal pipe. Place the stake or pipe 8 to 10 inches away from the plant and anchor 12 inches of the stake or pipe in the ground. This allows space for the hook to form.

Use a temporary stake to prevent wind damage to your kale until it is tall enough for you to tie it to the permanent stake. As with tree kale, when your walking stick kale is 18 inches tall, tie it to the temporary stake using a loose figure-eight loop at 12 inches above the ground.

As your walking stick kale grows, add additional loose figure-eight loops every 18 inches. You should be able to begin tying your walking stick kale to the permanent stake by the time it is ready for tying the second or third time. At that point you can remove the temporary stake and make the lower ties to the permanent stake.

All of your ties should be loose enough to allow the walking stick kale to slide down the stake under the weight of the leaves growing at its top. The weight of the leaves and the plant pull the stalk down to the ground from the bottom.

When the stalk slides down close to the ground, dig a space underneath it so that it will sink below the level of the soil. Place the soil you remove as you dig over and around where you believe the crown of your walking stick kale is to prevent any roots from being exposed as the crown of the plant shifts in response to the weight of the sinking stalk.

Continue removing soil to allow the hook of the walking stick to expand until you believe that it is about 6 inches below the top of the soil. When the hook reaches that level, cover it with soil so that it begins to harden as a tree root does. Prune off any shoots that appear.

Your walking stick kale should have grown to about 5 to 6 feet tall at this stage. Because the last month of the plant’s growth will be porous, it will not dry hard. Instead, it will be slightly spongy. For that reason, you need to be sure to continue watering and fertilizing to encourage your walking stick kale to grow as possible towards the end of the growing season. You need enough length to serve as the shaft for your walking stick you cut off the spongy section at the top of the plant.

At the end of the growing season, leave the stalk in the ground. Dry winter air will draw moisture from the stalk and cause it to harden further.

By February, your walking sticks should be sufficiently hardened to pull your plants from the ground. Shake the soil from the roots and cut them off at the crown of the plant. Use twine to hang your walking sticks by their hooks in an airy space where they will be sheltered from rain and allow them to dry until about July.

When your walking sticks feel like they have enough weight, hardness, and stiffness to successfully hit a golf ball, lightly sand them to remove spurs around the leaf scars, and then seal them with varnish. Protect the tip of your walking sticks from wear by adding a cap called a ferrule.
