Our tree which is well established has turned brown and appears to be dying from bottom to top ie. turning brown with a sticky syubstance oozing through the bark. A clematis that we had planted this spring to grow up it also seems to be dying ie leaves growing then dying back.I think it might be a fungus. Is this probably correct? If so, can it be treated or should I cut it down and remove it?
Leave it be until next year and see what happens. Sometimes monkey puzzle comes back from the base.
