    T1 Sycamore- remove 3 epicormic stems at the base of the tree (approx diameter 10 cms each) Reduce central top height of the tree by 2 meters and reshape the crown all around. Reasons- the tree has not been worked on for some time and it is cutting out light at the back of the property and for other properties in the vicinity. It is a very tall tree for the confined space that it is in.
