Cold temperatures make tapping Vt. maples tricky

Posted: Updated:

MONTPELIER, Vt. (AP) - Experts say maple producers should be "very careful" if they have to set maple taps in very cold weather.

Tim Perkins of the University of Vermont Proctor Maple Research Center says besides damaging the growth layer of the tree, tapping in extreme cold can also reduce the sap yield by creating a leak. Perkins says not every producer will be out this early, but large operations with more than 10,000 taps "need to go out" because it's a time-consuming process.

Kyle Branon of Branon Family Maple Orchards says trees can withstand this kind of cold but tapping into them during extreme cold risks creating cracks.

Paul Palmer of Palmer Lane Maple says he will wait for warmer temperatures but if he had to tap now, he'd worry about splitting trees.
