Doctor Perkins,
Is there any truth to the idea that the base of the trees have to have the snow melted back away from them a foot or so for good sap flow? I was thinking that with the amount of snow around the base of most trees right now, we would be looking at three weeks or more before the base of trees are free of snow.
