on the insides of the branches will remain at Stage One or Two and not reach

Further Notes on Spring Buds and Repotting Times

It is not easy to immediately identify the different stages of Spring Buds until
you are familiar with a particular species, as their appearance differs from
species to species. However, the basic descriptions of a winter bud, a slightly
swollen bud, a lengthening bud and an opening bud does hold throughout all
species. If you observe all of the buds on any particular tree, you should be able
find and compare examples of at least one or two of the 4 stages, sometimes with
3 or 4 of the stages occurring on just one branch (like that of the Kiyohime
pictured above).

Repotting can be safely carried out when the buds are swollen and extending,
repotting is best carried out when the buds are extending.

Repotting can be carried out when the buds are dormant but will result in a
loss of vigour in the tree until it recovers the 'energy' lost from the roots. For this
reason, winter repotting (repotting when the buds are still dormant) is not
advised.

There are exceptions to these rules but as a fail-safe and general indicator,
repotting should not be carried when the buds begin to open.
