    Magnolia in the rear garden- Reduce crown by 1.5 Metres on North, west and southern aspects Lift crown to a height of 3 Metres from ground level This tree has a twin stem that twist across each other, with a bark inclusion at the division, reducing the crown will reduce forces at the division reducing the risk of the tree failing at this point during storm condition. In addition the tree has out grown its position in the small garden and the crown reduction would be in keeping with the character and dimensions of the garden
