Established trees and shrubs should be only moved if necessary as even with the best care the tree or shrub may fail to thrive or even die. Renovation may be an alternative.
Plants resenting root disturbance such as Rosa, Magnolia, Cytisus and Cistus can be tricky to move.
Young plants transplant fairly well, but more established specimens will suffer greater stress and require advanced preparation. As a rule-of-thumb, plants that have been growing in position for more than fiive years are much less likely to survive transplanting than younger specimens.
Consider using a specialist contractor to move mature plants or a large number of trees.
