Black Walnuts, Sap Flowing, Sugar
Today turned out really nice, temps. in the mid 30's and sunny so it felt really good. I walked by my black walnut today and noticed a couple branches which had had the tips eaten off some time this winter. Much to my surprise, both the broken tips were dripping sap. This seems strange since the tree won't be leafing out until late May approaching Memorial Day. Do dormant trees run sap during the middle of winter on warm days? Is this tree crazy?
To add to my surprise, I tasted the sap and it was quite sweet. Could black walnuts be a substitute for sugar maples?
