  T1 Lime tree Crown thin 30%, remove deadwood The tree is 25m high and the centre of the canopy is very congested. Thinning would improve light to the surrounding gardens and the removal of dead growth (incuding some very substantial dead limbs) would be in the tree's interest as well as the welfare of those using the gardens beneath.

  **FIVE DAY NOTICE** The American Red Oak in the rear garden is dying. The foliage is very sparse and bracket of the heart_rot fungus _ Ganoderma applanatum are evident. As an alternative to felling, I'd like to try a substantial reduction of 40% to see if the tree could survive a little longer, without the stress of supporting a full canopy
