We have an ugly wall (actually a neighboir's garage) at the foot of our garden. I'm considering putting some horizontal wires across it, a couple of feet apart, and planting some fruit trees in largish square pots, with a view to kind of training them up the wall.
I am quite the beginner, and I'm not really sure where I've got this idea from. Is it nuts? (Or apples or pears? Badoom tish!)
