Hi, I am 'adopting' two fruit trees from a friend (pear and edible apple, I think). Both are about 6yrs old but have been kept small, 6' high max and have recently been trimmed too so they will be around 3-4' across at the most. The trunks are around 6" thick as I recall. How big a root ball should I dig on each to transplant them? Also, in a similar vein - how drastic can I be with pruning a mature apple tree? I already have a ~30yr old bramley cooking apple tree, but I haven't pruned it in the 5yrs I've been here (health problems have stopped me, but sorted now). The crop last year was rubbish, it really needs a serious prune now before it blossoms but I really don't know where to start! It's mostly gone straight up and out, lots of long, straightish branches which I guess need to come out? Thanks.
