Hello Michael

First of all welcome to the group.

There has always been a lot of discussion on the potential damages caused by tree shaking. To my knowledge tree shaking has a positive impact on the trees, promoting soil aeration and the development of new roots.
It can only be dangerous to the very young (which might be your case) or the very old trees; where the shaking can severely damage either the trunk or the main roots.

In your case I would exercise caution, if you have any doubts that your plants can manage the shaking just wait another year. It’s better to wait a year than to waste three or four years recuperating trees that where severely damaged.
