Tree Kale/Collards

Posted on October 7, 2010 at 1:19 AM

I have many readers of this blog whom I have had the good fortune to get to know better through regular blog comments, email correspondence, and even an occasional real life garden visit.   One such reader is Cherie.   She contacted me by email quite a while ago and ever since I have enjoyed corresponding with her about our gardens and related challenges.   Recently Cherie wrote that she had noted I mentioned how much my chickens really love kale.   She suggested that to keep up with their demand perhaps I might want to consider growing some tree collards.   Apparently she had obtained cuttings of this perennial non-flowering cole crop from John Jeavon’s gardens in 1990 and has been growing them ever since.   They grow very tall (over 8 feet tall in fact) and are apparently just as tasty and sweet in winter as more traditional kale and collard crops – but produce year round and can grow for several years before a new propagation is needed from cuttings.   She was kind enough to offer to send me some cuttings from her plant if I was interested – which of course I totally was!   Perennial vegetable plants are a bit of a rarity and finding one that is also a cole crop, which grows very well in my climate, is a home run.   Here’s a video clip that talks about this interesting plant and it’s usefulness in a food production garden.

Tonight when I got home from work I found the package had arrived in the mail for me with several tree collard cuttings – as well as a package of some hull less barley seed to trial in my garden.   It was like Christmas in October!   Not only did I get the cuttings and barley seed, but she also sent a nice fact sheet on the plant describing how to grow it from cuttings and how to harvest and use it.                                 

 

     

 

The cuttings survived their U.S.Postal Service journey in good shape and I did not want to let them sit any longer than necessary before getting them attended to.   These plants have several obstacles to get through before they can become mature specimens in my garden – not the least of which is just surviving this journey and growing out roots from the cutting.           

 

    

 

Before I got started, I gathered up the soil mix, pots, cutting board, and sharp knife that I needed to do the planting up process.   The first step is to then cut about an inch from the bottom to reestablish a clean cut that will take up water more readily.   That is easier said than done, as the stems are incredibly woody and tough!             

 

    

 

This was then placed cut side down into a container of very moist potting soil mix ensuring several leaf nodes were below the soil level (this is where the roots will form from) as well as several leaf nodes above the soil level (this is where the new leaf growth will form).           

 

   

 

They don’t look like much at the moment, but they hold a lot of potential.     

 

  

 

If I manage to grow these out and don’t kill them along the way, I will post some updates periodically about them.   In the meantime, I just want to say a big thank you to Cherie for her thoughtfulness in sending these to me.   Hopefully I will find an opportunity to pay the kindness forward to someone else in the future.

Very interesting. I've heard of Sea Kale which is a perennial brassica, but never tree kale before. I'd have trouble with it since I always cover my brassicas instead of spraying with bT. But it seems like a really interesting plant. Good luck with the cuttings.

This is so interesting! Do you know if they would overwinter in zone 6? I wonder why more folks aren't growing it.

That is so neat. I'm going to have to see if I can grow them here. The girls would love it.

Daphne - I could use your good luck wishes... notalways had great success with rooting things out from cuttings.

Thomas - According to the fact sheet provided.... "Tree collards will grow well in most temperate climates, although there may be approximately 75% die-back if tempatures drop to 6 degrees farenheit and stay there for any length of time. In this kind of environment, take cuttings one month before the first hard frost (or use prunings);, flat them and keep them in a greenhouse to overwinter; one month after the last hard frost in the spring, transplant the cuttings." I suspicion these are not more commonplace because in general American gardeners are not all that keen on growing even annual kales, swiss chard, and other mustards and greens. Given these are a longer term space commitment, I imagine only those of us that appreciate kale (or have chickens that love kale!) and know the high value of this as a food crop would be terribly ecited about them as anything but a novelty item.

hsheather - I think this will be a great greens crop for my chickens as well as using the more tender young shoots to provide kale for our table as well.

This is very interesting information as we too have a small patch of tree kale growing in our garden for the first time this year. I am hoping that it will overwinter for us and then perhaps I will try rooting cuttings like you are....how fun. Good luck with yours.:)

Mike - It will be interesting to compare notes on this experiment with you. Your winters are harder than ours by some order so how they do there versus my area will also be interesting to see.

Very interesting! I've never heard of tree kale. Maybe if you get yours established you can share a cutting with me in the future.

Over at my blog, I've invited you to participate in a "A day in the slow life" meme started by Toni at Backyard Feast. It would be great if you could join us.

Sandy - I will go check out the invite! As for future sharing of cuttings - I would be very happy to share them with you. Hopefully I will be able to successfully grow these out so I can!

I'll be interested to see how you feel the taste compares to annual kale. Keeping our fingers crossed that the cuttings work out for you!

Dear Laura, Did you ever get your tree collards to grow? If so, do you have enough to share some cuttings? I have been looking for these for a while now and I'm excited to get some growing in my own garden this year.

Thanks for your help,
Lynda

foodgardenkitchen - I will try to continue doing periodic updates on how this trial goes.

Sindy, Linda, Tsitsi, Aaron Ellis, and Lynda Swink - I do not have any leads on where you may get starts of these plants as a search online did not yield much other than one source indicated they occassionally have them for sale. I would encourage you to do your own online search and see if you can catch a source when they have them available. For those of you asking for starts from my plants, I only had one that survived from the cuttings and I need to grow it out more before I can consider doing any cuttings for other folks - probably be next year realistically.
