A practical guide for the management of a sugarbush. Guidelines are established for the manipulation of stand density and stocking to promote the development of healthy vigorous trees with deep, wide crowns, the necessary attributes for highest possible yield of sugar-rich sap.

Virtually all of the pure maple syrup production in the United States is in the northern states of Maine, Masachusetts, Michigan, New Hampshire, New York, Ohio, Pennsylvania, Vermont, and Wisconsin. Pure maple syrup users living in the maple production area and users living in other areas of the United States were asked a series of questions about their use of pure maple syrup and their responses were compared. User attitudes toward the product, syrup-use patterns, syrup-packaging characteristics, and syrup-purchasing patterns are identified and discussed.
The seeds of a sugar maple tree do not mature at the same time every year, and different trees mature their seeds and different times So time of year is not a reliable measure of when seeds are ripe. In recent studies we have found that moisture content and color are the best criteria for judging when sugar maple seeds are ripe.
Some maple sap producers have wondered whether they could increase the total sap yields by tapping their trees not only in the sprint but also in the fall too. Our research indicates that tapping in the fall cannot be recommended.
