The average maple tree will produce between 9.2 and 13 gallons of sap per season, which is roughly equal to 7 percent of its total sap.
Sugar maple trees can live to be 400 years old; after about 140 to 150 years, they stop growing in height (110 feet maximum) and grow more slowly in diameter.
A tree should be 10 to 12 inches in diameter (40-50 years old) when measured 4.5 feet above ground level before it is tapped for sap.
Maple syrup can be made from the sap of red, black or bigleaf maples as well as sugar maple trees.
