If your azaleas have finished flowering and you need to prune them back to control their size and shape, now is the time to do it. Remember that azaleas have adventitious buds under their bark so you may prune anywhere you need to, even on old hardwood, and they will re-sprout. Make sure they are well fed with Holly-tone so they fill back in quickly. If they regrow a bit irregularly you may need to prune again in mid-summer. After that leave them alone to set up their flower buds for the following spring. – ‘Plant Doctor’ Bob
