How much sap does a maple tree produce, and how long is the season?
The amount of sap produced by a sugar maple varies according to the tree’s size. A typical tap tree (12 inches or more in diameter) produces about 10 gallons of sap per season. The sugaring season can start as early as the second or third week of February but usually commences about the first week of March in Vermont. According to the University of Vermont’s Proctor Maple Research Center in Underhill Center, the latest recorded boiling of sap occurred on April 23, but this late date is rarely achieved. The season is dependent on the weather.
