I have a Harry Lauder Walking Stick and it has a fungus on it. I tried Neem Oil and it stopped it for a while, but now it is spreading to other areas including the trunk. The leaves are dying off also. Is there anything else I can try to kill and stop the fungus?
It is hard to know without actually seeing the plant but I can tell you that there is a blight that shown up that attacks filberts including Harry Lauder Walking Stick. If that is what it is then there really aren,y great options. HERE’S MORE on that disorder.
