I've found two cases of "Eastern filbert blight," one in Woodstock and the other south of High Falls. The initial symptoms sound similar to yours. Look for black scaly spots along the trunk. If your plant has the blight, it's probably best to remove and send to the dump. The cures offered seem to be most useful to filbert orchardists. More info available, just search for eastern filbert (or hazelnut) blight. Sorry. |
