Warm days and cold nights make that sap run! But why? During the day, when temperatures rise above freezing, pressure develops inside of the tree. This pressure wants to release, and can do so by pushing sap out of an opening (such as the ones that we create). As temperatures fall during the night, suction (or negative pressure) develops within the tree. This causes the roots to take in large quantities of water, which can be used to replenish the sap. This replenished sap will flow again during the next warm period. With sugaring season comes many long standing traditions: sugar on snow, music playing, sap boiled hotdogs, etc. What are some of your favorite traditions?
