Very Early Spring 2014 – Tapping the Sugar Maples!
Yes indeed, spring has sprung! And not only because we set our clocks ahead, but more importantly because sap is flowing from our maple trees which is a more certain sign of spring! We are very excited, especially since maple syrup will be one of the very first “products” of the homestead. I am convinced that it will be well worth the work involved in its production.
Maple tree sap flows when daytime temperatures exceed freezing, 32 deg F, and nighttime temperatures dip below the freezing mark. The temperatures above freezing create a “positive pressure” within the tree, forcing sap out of the tap, while temperatures below freezing create a “negative pressure” within the tree, causing more sap to be pulled up from the roots and into the sap wood. [1] The optimum variation is said to be a high of 40 deg F and a low of 20 deg F; we tapped Sunday morning at about 9 a.m., after an overnight low of 17 deg F and leading to a daytime high of 42 deg F, and sap was flowing by noon the same day!
