Barberry

Question

Can I rejuvenate prune a Barberry? What time of year would be best? I have come across some barberries that have been neglected for about 10 years, minimal foliage and a lot of dead. Any advice would be appreciated.

Answer 1

Yes, you can rejuvenation prune barberries, or better renewal prune them, which is the gentler version where you remove 1/3 of the branches each year for three years. Spring is the best time so the cut branches won't be stressed during the winter. Here is the answer a university extension agent gave to someone with a similar question:
