I'd be really grateful if someone could help : Grows on You

Leicestershire, United Kingdom

I'd be really grateful if someone could help.I have a corkscrew Hazel in a large pot i've had for years.The poor thing seems bomb proof.It's very pot bound and i'm really surprised how well it's survived drought and neglect.I was going to get rid of it last week,but suddenly realised i was quite attatched to it.Can i rescue it?or will it be a massive job?I cant put it in the garden,it will grow too big,and no room.But i would buy it a much bigger tub,as i know you can get really big ones. All suggestions gratefully recieved! Thanks.
