I posted a couple of weeks ago about a Kilmarnock willow and have

a
new one, or would I be better off waiting till spring?

I think the general theory is that one should plant hedging and trees
in autumn (wait a bit yet) so that the root system has a chance to
establish and develop before it has to support rising sap and leaf and
stem growth.
Also the theory goes that it should be wetter in autumn and winter so
you don't have to water quite so much.
