The process of how sap moves in the tree.

That's pretty interesting. Makes sense.

Curious how a bit of information shed on a subject can change your perspective. The value of the warming days of late winter isn't just that they thaw out the tree from the previous night's freeze, but that they slow down the freeze for the upcoming night.

I'll be keeping an eye more on how the late afternoon/early evening cool down.
