Birch tree on balcony?
If I put it in a BIG pot, like the ones you see with trees
in them on city streets usually downtown etc., would it be OK in zone 4?
Or does it get too big? Would I root prune?
I am going from 17 acres to a 10X9 balcony. I need trees!
Will do dwarf confers but I also want a birch (river) tree.
Anybody done this? Do they just look scraggly?
