The problem with using ice cubes on the ground is that roots have no
chilling requirement in any species of which I'm aware.  Chill units seem
always to be collected by individual buds (axillary and terminal) on the
branches.  The chilling response is not transferred from one bud to
another; each bud must collect its own chilling units.
