Hello again. I was weeding yesterday and noticed that my two lilacs are being attacked by some sort of fungus. The fungus seems to creep up from the bottom of a trunk with the start of a little discoloration. The fruit of the fungus is most apparent on the largest trunk affected (which is the picture I show). I did not have the chance to see how the leaves dropped or how long it took, but the leaves on the effected trunks/branches are all gone. I removed most of the effected parts and inside was all dead wood. Is there any chance of saving the rest of the plant? What can I do?
