I think they are OK but could be a bit delecate and maybe not so hardy for some parts of Scotland, we were told that by a grower and I can understand why, however we bought some trees from a garden center, 2 apples and a pear and plumb tree, the plumb died as it was planted where our tiny pond used to be, i think it got gasses by build up of wet in the ground, it looked great for a year then just died...the rest of our trees are great and we have apples but no pears as yet!!! I also had a nut tree from my daughter and thats wonderful, think I will get some nuts this year, it looks very healthy!!!
Our main issue is some scrumping, we lost all the apples 2 years ago as I kept thinking I would leave them a day or two, then they disapeared.
