No Bill, the tree will heal on it's own, provided it was healthy to begin with. Older spiles (taps) were 7/16" diameter, while the newer ones are 5/16" diameter, in order to expedite the healing process. Nature begins to heal the wound as soon as you finish drilling the hole, and the sap will run less and less as time goes on. By six weeks or so the taps begin to dry out, as the tree closes off the wound.

I'll see if I can remember to grab a photo of a healed-over tap hole from last year.

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
