At least in the Red River Valley (ND and MN), many of the green ash seem to be dying .... lower branches first and working into the crown. In addition, some of our trees appear to have trunks and older limbs that are bending excessively and cracking in the wind ... almost like the trunks are losing strength and wilting. Is it a disease or related to weather?
