The size of the garden has a big influence on the size of trees and shrubs that can be grown. Tall, broad trees are not suitable for small gardens. Narrow trees, weeping forms and standards (trees with a clear stem) take up less space.
Large trees need space
Check the position of drains underground and wires overhead. Do not plant trees with vigorous root action, such as poplar and willow, over drains. Do not plant tall, fast-growing trees beneath overhead wires.
Observe the view from the garden and the main windows. Position trees and shrubs so that they block unsightly views, but frame and emphasise pleasant views. A tree planted close to the observer will more quickly block an unsightly view than if it is planted close to the object to be hidden.
Finally, locate trees where they will look best – setting off a building, framing an entrance, on a lawn as a specimen. Try to imagine a mature tree in its position.
