    I would treat the hole with a fungicide to help slow any rot. Also, if you can cover (do not plug) the hole to keep water out. Trees can live with holes in their trunks without problems as long as the bark and first green ring of wood (which is what keeps trees alive) is healthy. However, in this case, you say it has darkened; therefore, I would recommend obtaining adivce from an aborist that specializes in these types of tree issues.
