Planting bare root trees is an economical and successful way of adding these to your garden. Available when dormant (usually November to March).
Carefully research the ultimate size of trees and plant them where they will have room to grow without the need for cutting back if they get 'too big'. Check that they will not interfere with foundations or drains, or adversely affect neighbouring properties. Too many trees are cut down because they were inappropriately positioned without thought to their eventual size.
