No, I don't replant it, I don't dig it up in the first place. I just find the idea of killing a tree for no good reason rather distasteful.
I whole heartedly agree with you Ged!
Why kill a tree just to make your house look pretty?
I dislike cut flowers in a house for the same reason - I would much rather use potted plants that are alive than the decapitated remains of a living thing.....
I used to have a live tree with roots every year and replant them after the 12 days were up - but a lot of them died.
Now I have an artificial tree (me - the man who promotes natural materials for as many things as possible!) as I can see no point in putting a living thing through the stress of uprooting and possible death purely to make my house look "nice" for a couple of weeks. The tree I have is mainly made from wire and paper...though there is a goodly amount of plastic in there too I am afraid. The same tree has been in use now for a good number of years so the global impact should be fairly low....
As to folk asking what you use to cook with etc - I use mainly wood. But it is not just to make things pretty for a couple of weeks then get discarded. My wooden tools should last the best part of a lifetime, firewood is (to my mind) a cleaner/more sustainable (low carbon footprint and all that) form of fuel than gas or petrol.
OK - you can carve your tree or burn it (I like the candle idea) but to be fair, a small tree is not the greatest carving or burning wood.
If a tree is cut down and only used for decoration for a couple of weeks then discarded to rot then I see the same ethics in play as those employed by "bushcrafters" who will cut a green tree down just to test the edge of their axe. I prefer to see living things alive rather than chopped down for what is basically vanity.
It is strange that (IIRC) the Xmas tree was originally celebrating the Spirit of Nature and the beauty of the great outdoors!
Well that is my logic for having an artificial tree anyway...... and I realise that I am in a minority with my views.....works for me though!
I find it refreshing that the OP was interested in finding an extra use for the remains of the tree - it shows (I think) a reluctance to waste the wood/life of the tree
