Typically, when you see "sap" unexpectedly, it is not sap but honeydew from pests that have infested the tree. Treat the tree with neem oil. You do not need to reach all parts of the tree, just what you can reach. The tree will absorb the neem and will carry it to all parts and will eliminate the pest causing the honeydew.
