TAPPING THE TREE:
The flow of sap is highly dependent upon weather conditions. Flow does not begin until after a time of hard freeze, followed by several sunny days with temperatures in the 40s. The peak flow occurs early in the sugaring season when it freezes at night and is bright and sunny the next day with the temperature in the 40s. The flow will stop when daytime temperatures do not go above freezing, or when night temperatures do not go below freezing. The flow usually lasts roughly three to four weeks. While it flows, collect daily the sap, preferably late afternoon. If the trees are tapped too soon and flow does not begin, it is possible that the holes will seal over and subsequent flow is inhabited significantly.
