- Cordylines, that trusty no-nonsense mainstay of gardens across the UK... or so we thought! Yes, the 2022-23 winter will go down as a terrible one for many plants including cordylines, which have taken a beating with the cold weather.
In this video, I'll show you how I've managed to protect my cordylines from the winter cold. I'll also show you what to do next if your cordyline looks completely dead.

Indeed for many plants that have been devastated by the winter cold, you should never despair of seeing them grow back. You just need a lot of patience because nature is never in a hurry and you have to wait until the end of summer to find out if they are definitely dead. Greetings from Brussels! I had mine whose stems more than a meter were completely fried in February 2021. After cutting everything and removing everything that was dead, they all came back and are still there in 2023. They will need a few years to return to the size they had.
Good tips👍
Thank you. Fingers crossed this is the final cold spell before spring kicks in 🤞
@@greatnorthernexotic I think the closer these plants are grown together where there's less isolated exposure they survive better. Bamboo, trees etc offer good protection.
Is it worth putting hormone rooting powder onto and around the cut where the trunk is not rotten?
If it's a rooting powder containing fungicides / sulphur, it should help in preventing further rot in the stem, but in terms of promoting rooting then I'd say that a cordyline's root system will be strong (with an extremely deep taproot) even if all growth above ground has been lost.
My Cordyline australis came back from the dead 15 years ago after a bad London winter and is now huge and wonderful! Some are saying the newish Cordyline "Charlie Boy" is reasonably tough - any view?
No personal experience but I know they've come back from harsh freezes for others. I'm surprised by the reported hardiness because the green species of cordyline invariably do better than the red leaved ones.
Thank you, how long would you leave it covered? Do you do this off and on through the winter or at the start and leave it all winter? thank you
I'd keep the protection on only for cold spells, then remove to allow the crowns to dry out.
@@greatnorthernexotic thanks for this, just a few days at a time, off and on when required then? Second winter with one in the ground, 8 feet tall
Hi, was just wondering if this worked for you? I left mine to see if they recovered but they havent so I'm going to cut of the top part of the trunk which has gone soft (until the trunk is hard) and see what happens, happy to receive any further advice but guessing this is the only thing I can do now :)
Hi, yes mine has thankfully regrown from the original growing point even though there was some spear pull. If you have no sign of regrowth by now I think chopping it back is the right course of action, especially if the trunk is soft. I'd cut off a bit at a time until all the soft parts have been removed. You might still be lucky and get regrowth from underground!
@@greatnorthernexotic thanks I'll give that a go :)
What if it's a tree and you can't reach the top?
Typically the older the plant, the hardier. Still, could you use a stepladder to temporarily tie up the crown or add fleece?
I've made the classic error. My leaves were all brown, and the trunk for a good 20cm was soft and wet. You could squeeze it. I have cut all the leaves back and have cut the soft squidgy part of the trunk. No new growth yet. The rest of the trunk is woody and hard. Does that mean I will be lucky and get new growth? I fear I may have cut it too early.
The fact that part of the stem is woody suggests the rot hasn't reached the root system, so the signs look good to me. The new growth may come from the stem but could come from below ground so I wouldn't worry about any signs of new growth yet. Keep me updated!
@@greatnorthernexotic Here's hoping. It was just a cheap £10 few years back, but grew into a mighty specimen - almost 2 meters and wooden trunk, So don't want to lose it. Would you cut it down to ground or cut down to the wood. At the moment - I have left a good 10cm above the woody stem.
@@Tomdexterscott as long as all the rot is cut away the plant will be fine. And don't forget even though you've lost height, it'll still have a solid root system so should bounce back pretty quickly. 👌
@@greatnorthernexotic here's hoping. I've had to saw more off, as that top of the woody bit of the stem seemed to be a bit soft. As I was doing that there was a strong smell of vinager. And the middle bit of the stem is spongey.
