Let's be honest here, Christmas decorations are not the most environmentally friendly thing in the world; the vast majority are made from unrecyclable plastic, and as for the tree, well it an be difficult to know whether a real or an artificial Christmas tree is actually better for the environment.
If you have decided to go for a real Christmas tree this year, when the 12 Days of Christmas over you will need to get rid of it somehow.
So what can you do with it?
If the tree is rooted and you have a garden you can plant it out, and if you have any sort of outdoor space you could re-plant it into a pot and then you could then reuse it next year.
If you have a cut tree you have various options.
