Tapped 7 sugar maples for the first time for sap to boil down to syrup. After a few broken drill bits, spills and burns, I got an 8 ounce yield which is the perfect viscosity and sweetness. Very happy. We have ~5 days of temperatures worth of production, then a cold spell. When the temps rise again will it harm the tree to retap if no sap flows? If so, is it better to bore 1/4-1/2 inch deeper in the same hole or create a new hole? Obviously I don't want to weaken the tree. Thanks.
