Selecting sugar maple trees for the program
Before completing this form, read about the Comparison Tree Method.
When a tree is suspected of having sap with above average sugar content, test the sap content of the five nearest trees. Record the results on the Sugar Maple Testing Form (below). Make sure to mark the tree with higher sap content and the neighboring trees with plastic flagging or in some other way. If possible, measure the selected tree and candidate tree several times during the sap season. The sap sugar content of the candidate tree must be at least 30% sweeter than the average of five surrounding trees (standards) and must exceed the sweetest standard tree by a minimum of 0.5 percent for the tree to be included in the program.
