I bought an acer palmatum today because it was cheap and will put it in a container for a while. This is not the problem.
I noticed on the label that it ultimately grows to 8mx8m!
The thing is, I had one that outgrew its container so I bunged it in a bed at the end of the patio on a live or die basis. It thrived and looks great.
My question is, do all acer palmatums grow to this size? Mine's a green one. It'll be fine for a good few years yet, but should I be doing anything to stunt its growth?
