Trimming Back Paniculata Hydrangeas in the Fall Prior to Transplanting
I need to move some paniculata hydrangeas and to make the transplanting easier I would like to trim them back now before moving next week. Can I trim them back like I do in the Spring which is usually to about 3 feet in height?

Yes you can prune your hydrangea this fall but ideally should wait until dormancy with most leaves dropped. Because paniculatas flower on new wood, as good or maybe a better time to transplant would be late winter, early spring, while the plant is still dormant but the worst of winter is past. Record cold temps around the state caused issues for a number of different landscape plants this past winter. Whichever you choose, get as much of the root ball as you can and make sure it gets watered well when transplanted as well as for at least the first year.
