Last Years Willow Cuttings

I repotted last years willow cuttings today. The primary reason I did it was because I like to play with my trees. Next it was: one year old willow cutting have got to be as hard to kill as fresh willow cuttings - which are very hard to kill - so these ought to be tough and can take a February transplant.
The yearlings had plenty of roots. I chose the lowest, most radial roots and chopped the rest. I planted them in cut-down gallon pots; and put them close to the house so they don't catch any sudden frosts.
I would not do this with a bonsai-ed willow. Willows drop branches when stressed. Don't ask what stresses a willow, the list is too long. Dropping branches is, of course, very bad for a bonsai. Take the utmost care to baby willows.
But the yearling trees have no branches - so either the "one branch" will die, or nothing bad will happen because there are no branches. I have stated why I don't think the one branch theory will happen.
