Appropriate Tree Planting
We have a small garden, but a neighbouring garden has a large ugly workshop with a metal roof that sits alongside our back fence. We want to grow a tree that would bush out over the fence line to obscure the workshop somewhat, but not take up too much room in the border. The position of the tree would be NNW; there would be no issue about casting shade, either in our garden or our neighbours. Our soil tends to be more acidic. Please can you offer any suggestions?
