I just trim by hand until I get them under control.

Hi Sandra, right after azaleas and rhododendrons are finished blooming is the best time to do any pruning they may need. These shrubs make blooms that flower on the prior year's wood. So you have to be careful when pruning them since buds for next spring will be made this summer, and you don't want to prune those off.

“Natural” for rhododendrons is tall, wide, and full. But I figure if the bushes are taller than the person trimming can reach, they will never be under control. They continue to grow all of the sunny months, so trimming once a season should be enough if you cut back the larger, older beaches and allow the newer branches to grow to be strong and healthy. I have seen rhododendrons live well past sixty years, so yours may live much longer. Enjoy the red beauty!
