How to train/prune a mulberry bush into a proper tree?
I have a black mulberry bush/tree which I planted in the garden about 18 months ago. It's now approximately 2 metres tall. I bought it as a tree, but it looks like a bush, with several branches radiating out from a central point/stem in the ground.
I would like to grow this plant as a tree, but at the moment it has no single stem/trunk. Do I need to prune it myself for it to take on a tree shape or will it eventually start looking like a tree on its own?? Any advice or suggestions would be greatly appreciated as at the moment I've no idea what to do with it. Thanks! :) Anita
