Beech tree (Parkside SK7)

I have a beech tree that was dug out some time ago and had been standing in my waterbutt since it still appears to be living but desperately needs to planted in a large space. This is a special tree it was planted as a tiny sapling when my childrens father died and I really didn't want to get rid of it but it's growing rapidly and the garden isn't big enough to accommodate it. I would love it to go somewhere where it can grow forever. I can't post a photo as it's too dark to get one but if you're interested please message me I can try to send a picture in the light of day. Thanks sue
