The International Society of Arboriculture does not recommend filling
cavities anymore because:
1) More current research shows that filling cavities may do more harm than
good.
2) Decay develops between the interface between the filler and the tree.
3) The fill material does not strengthen and support the tree as much as
the new callus growth that develops around and over the wound.
