  Communal area (rear of 18 Highbury Terrace) (T1) Lime (Tilia spp) - On the MEWS side of the tree, a (maximum) reduction of 5-6m of the overlong branches (including height), reducing them back into the crown so that they are balanced with the lighter reduction on the communal garden side. On the communal garden side reduce the overlong branches back into the crown by 3-5m. This needs to be a sensitive reduction, balancing the crown, maintaining natural shape, whilst significantly reducing the weight in the upper crown . Remove all deadwood from the crown. Remove all trunk epicormic growth N.B. The aim of this reduction is to reduce the overall crown whilst retaining as much natural shape to the tree. (T2) Laburnum (Laburnum anagyroides) - Crown reduce the height by 3m, reduce the lateral growth by 1m to create oval shape.
