We have a large honeysuckle against an east facing fence. It is several years old and about 7ft tall (Tree ) see photo. Unfortunately I do not know the type. For the last few years the tree has ended up looking very unhappy and sick, after a healthy start. Have been spraying the tree with fungus fighter but to no avail. We do not want to remove it if we can cure it.

Any advice would be gratefully received
