100% historically approved · decision due ~16 Oct
Lime tree in the front garden: Rempve epicormic growth to crown break at about 5m, and remove lateral epicormic growth growing over the front garden from the stem closest to the building of No.35; retaining shortened (about 0.5m long) vertical epicormic growth at the top of the stem, and retaining epicormic growth (on the same stem) that is growing towards the centre of the tree. the reason we need the work done is to observe the Jewish festival Sukkot when we build a temporary hut for the duration of the festival and reside in it. It is a requirement that the sky should be visible through the roof of the hut, hence the need to prune the tree.
