barberry bush restoration #926649

Asked March 24, 2026, 12:27 PM EDT

Hello: I have a couple very old (+20 years) barberry bushes that require restorative pruning—lots of dead branches. Does OSU have any publications specifically about restorative pruning? I live in central Oregon. Thank you!

OSU doesn't have anything for barberry bushes or specifically restorative pruning. All I found were for grape/vineyards, orchards or roses.

The best I could find, and I'm not confident in either one, is a 2004 publication from Iowa State University - 22 year old science and a very different climate. It might be worth a read, though.
