Just after a bit of advice. At the end of our garden is a first floor flat with the kitchen window overlooking us completely (Clear glass so breach of building regs but I’m on to that with the council) We want to plant a tree to block the view of our garden but the space where It would need to be is 2-3 metres wide between our garage wall and their wall. I know nothing about trees and worry if a silver birch which is tall and narrow and would fit In the space above ground may cause damage to the buildings with the roots. Can you even grow a tall tree in a pot? Any advice much appreciated thank you.
