After much research I've decided on a Paperbark maple for our garden - but now I can't find one in my local nurseries and the internet prices vary greatly. Also - I feel nervous about buying a tree I haven't seen. Does anyone have any advice on what size to buy this kind of tree - maybe even where! I'm in South Norfolk. I'm a bit of a novice gardener and a very novice tree buyer so any advice eagerly awaited.
