  We planted an olive tree in the bed on the patio behind our house in 2004. It has apparently found a water source and grown much larger than originally expected. We have pruned it regularly, but it has continued to grow and is now disproportionately large for a relatively small patio area. Unfortunately, it has attracted a fungus, which produces substantial amounts of white residue and sticky deposits, which render the use of our outside space effectively impossible. We have taken advice from a tree surgeon, who has told us that without knowing the source of the infection (probably another fruit tree) it will not be feasible to eliminate this. The tree is also now too big to treat. In the light of this, we are seeking permission to cut the tree down.

  T1 Betula jacquemontii- Fell- This tree has out grown its position in the small herbacious border and garden, it is blocking light and the roots are suppressing the growth of other ornamental shrubs and trees- The owner would like to remove it before it gets any larger- a poor choice for such a small garden, also blocking the view in to Green park. T2 Prunus sp.- Fell As above , in addition the trees lower branches have been removed and now has impaired form, is being suppressed by the London Plane tree and it has very few blossoms in the spring. If nessessary the tree owner would be prepared to replace the two trees with a more suitable tree
