Wonderful poem there bout trees.
Joyce Kilmer may have said it best:
I think that I shall never see
A poem lovely as a tree.
A tree whose hungry mouth is prest
Against the earth's sweet flowing breast;
A tree that looks at God all day,
And lifts her leafy arms to pray;
A tree that may in summer wear
A nest of robins in her hair;
Upon whose bosom snow has lain;
Who intimately lives with rain.
Poems are made by fools like me,
But only God can make a tree.

Thank you for that Tom,
That indirectly leads me to a little more evidence to say that pruning during dormant season won't necessarily increase the occurrence of waterspouts, assuming a similar, proper amount of branches are removed.

In the absence of energy-burning pumps, stuff moves from areas of high concentration to areas of low concentration. Don't think of it as water moving up and sugar moving down, although that may well be the directions most of the time. Water (and sugar) moves from where it is to where it isn't, if there is a path for it to follow. Yes, water content doesn't vary much, although water "potential" or tension can vary and certainly flowrate does!
The link is OK, but unneccessarily speculative. Although more than a few details still need to be worked out, and this text is getting a bit old, what we do know is largely in the text "Xylem Structure and the Ascent of Sap" by M.T. Tyree and M.H. Zimmerman (2002, Springer Publishing). It is a bit stiff going in places. Before Mel Tyree retired from the Forest Service (he is on the faculty of Chinese University now), I tried to cajole him (as his supervisor) into writing a simpler treatment for practitioners but it didn't happen. Maybe I'll get to that.
If you're interested in that book, check out your library or interlibrary loan. No need to buy it!
I'm not sure how the link relates to sprouting, but I often miss stuff!.
