Until recently we've had a lovely magnolia and a leylandi tree in our back garden. Unfortunately our neighbours were not happy as they were overhanging into their garden so we've had to cut them down. This has left us exposed to all the neighbours and the garden looks rather bare! In order to regain some privacy, not to mention all the added benefits of trees, I'd like to plant some more that will provide a bit of cover but not be too unmanageable - I was thinking something tall and thin but with enough foliage. My gardening knowledge is somewhat limited so any advice would be much appreciated, thank you!
