Q.Can Apple Trees Get Eastern Filbert Blight?
I have a filbert tree that has the blight, several other trees already died and were removed. Today I think I saw the familiar bubbles under the bark on my apple tree. Is it possible that apple trees get it too? And will it kill them also? Is there anything I can do?
