This tree is at my FIL's house and each time I'm there I take a look around at their yard. Now I never noticed this until today so I'm thinking this is a fairly recent issue going on; perhaps in the last month. Much of the sap leaking out is clear and crystallized like glass. There does not appear to be any injuries or insect damage to the tree whatsoever. There are very many areas from the trunk where the sap is leaking out and no limbs have been cut off in the last few years. I've taken several pictures. Is this either normal (I'm not thinking so) or is there a borer problem in this tree?
