Hi, just wondering if anyone has any thoughts or experience of these trees, been given a 4ft high young tree for free and I don't know whether it is a good idea to plant or not to plant. How much space around it would it require? I have googled and realise they can grow very large, can they be controlled to grow smaller? How long do they take to reach sizeable spread? Any advice really, I haven't a clue, even after looking it up, unsure.
