Weeping Willow Diseased

Asked June 10, 2019, 7:32 PM EDT

Is there anything that can be done to save any part of this tree? There is a large crevasse in the bark on the east side of the tree that extends from the first fork down to almost ground level. When tapping on the tree, there is a hollow sound on the north facing side. Saw dust piles are found on the north and west side at root level. I observed a single small black-metallic green beetle crawling up the tree on the south facing side. No other beetles were observed. I have another willow is an infestation of some kind?

Willows have many problems including breakage which opens them to fungi and insects. Seeing ‘sawdust’ indicates insects inside, which may be borers, carpenterworm, or carpenter ants. A professional should go over the tree and give a care plan, including specifically determining what insect is causing the sawdust, whether the insects can be controlled or eliminated, and whether the tree is structurally sound.
