When Do You Prune Rhododendron?

Question

My rhododendron has just finished blooming. I have read conflicting articles where one states that I should prune it now and one source said to wait until the fall.

Answer 1

Both now and fall will be highly inappropriate. I would wait until winter when it is not actively growing. This isn't necessary and should only be done in the case of disease and heavy overgrowth, however.
