Where can I plant trees to take me to new heights?

What is the best way to use trees in my garden design? Neil Beacher, Winchester, Hants

Trees bring height and texture, as well as colour. Some produce flowers and edible fruit, and they are great at attracting wildlife. They make an ideal focal point at the end of a path or in the centre of the lawn. If you’re short on space, compact trees such as Japanese maples grow well in containers.
