What to do with overgrown rhododendrons?

Posted in Plants, Pruning, Uncategorized at 5:36 AM by Administrator

We are often asked ‘is there anything I can do with these overgrown rhododendrons’. If you think, I need to rip out those overgrown rhododendrons, you might be right but you can also prune them back into shape. Rhododendrons that are blocking your windows may be a problem but you have options.

During 2019, we reduced the size of many overgrown rhododendrons that were blocking some windows by pruning them extensively. We decided where to prune based on each plant. By that I mean, we made some pruning cuts about 2’ above the grade while other cuts were done at 3’ or even 4’ above grade. The cuts were made so that we would keep some of the green leaves on the plant and so that we will have clean cuts at branch intersections. The following pictures show what an overgrown rhododendron looked like when we showed up and how it looks like after we pruned.

Most of our extensive pruning of overgrown rhododendrons was done before June 15th so we expect all of those rhododendrons to flower next year. This rhododendron was pruned on July 29th. Because of the timing of the pruning, we expect the foliage to continue to grow but we do not expect this plant to be full of flowers next Spring.

For information about why we try to prune all Spring flowering shrubs before June 30th and that we prune summer flowering shrubs from August 15th to September 30th, please stop by our office at 111 Newburyport Turnpike {Route One} in Rowley, MA or call us at 978.948.2900.
