how to tidy up this 'tree'?
not sure what's the name of the green tree but i'm sure experiance gardeners here could jz tell by a glance.
It's going quite wild now as we dont know how to trim it or cut it down to properly shape it so it actually destroying our neighbour's fence.
Please help and give us some suggestion or advise. thank you
p/s:I wont wanna cut it too much as i know it has been housing some birds deep in the center.
