Does anyone know if you can train a plum tree as an espalier? I have heard that you cannot but I don't know why. I already have a fan trained plum, but I have found this to be an awkward method of training. I have a couple of espalier apples and these are nice and easy to train, so I am hoping to do the same with a plum.

I think that plums tend to be fanned as it suits the way their branches bend and the way they fruit but not 100% sure. Personally I find fans easier to train than espalliers by the way! Funny old world...
