I have a large property line Deodar cedar (10 - 12 m.) that appears to be dying. It has always flourished, regardless of weather, and now, instead of being green and bushy, it's pale, spindly, and weak looking. Deodars generally seem to do well in the summer, so I don't think our present drought is affecting it. Recently, we noticed 2 series of about 20 holes in the lower part of the trunk (note line of holes across bottom of trunk, and again a few feet up). Could this be linked to the health of the tree? Do we have woodpeckers? bugs? neighborhood saboteurs? Before I call an arborist, does anyone have any thoughts?
