Apple tree

At long last today I got around to repotting my apple tree that desperately needed a bigger pot or rather tub.
My son grew this apple tree from a pip when he was about 10 years old I think so it's been with me, including a house move, for 27 years but sadly no apples.
Although I could put it in the garden I quite like it as a 'bonsai' patio tree although next time it needs a larger pot I may need to rethink this as its now in the largest tub the garden centre had.
