Will a Canary Island Dragon Tree survive the outdoors in England?

Hi,

I'm looking for some advice and help.

I have a 15 year old canary island dragon tree that I've grown from seed.

It's lived it's life indoors but has now grown too high to fit in my house.

I have now moved it outside and really want to keep it there. Picture attached.

Problem is I don't live in the Canary Islands, I live in England (UK).

How can I make sure it survives the winter? Can I wrap its trunk up in something to insulate it and put something over the leaves to protect them from frost and icy cold winds?

I've read it may survive down to -5C, but is this true?

If it really won't survive outside is there any way I can give it a serious pruning and chop it down in height so it can continue to live in doors? How much could I chop off without killing it?

Please help, either how to keep it outside or how to reduce its height?


Thanks
Toby

 

Looks more like Beaucarnea recurvata (syn. Nolina guatemalensis) than
Dracaena draco, so no it's unlikely to survive outdoors. Planted in the
soil, some subtropicals can tolerate a few hours below freezing, not days
of freezing weather in temperate climate.
You can cut it back but re-sprouting isn't guaranteed.
