Coppertina Ninebark Decline

Asked September 14, 2019, 10:10 PM EDT

I planted a Coppertina Ninebark 5 years ago, and it did well. However, the shrub not been as vigorous and full as it was previous summers. I have attached a pic of the shrub for you to see. It has lost most of its lower leaves, and it looks unhealthy. It does not receive full sun. Could that be the problem? I appreciate your advice as to whether I should move it or hard prune it or give up on it. Thank you for your help.

Hi - These shrubs grow best in full sun, so it is very likely that the decline has to do to the lack of sufficient light. If you do have a better location for it, fall would be an ideal to transplant it. Be sure to keep it watered regularly during the first 12-18 months of re-establishment if the weather is dry. These are generally pretty tough shrubs, so I wouldn't give up on in if you have another location for it.

Ninebarks are best pruned after they bloom in the spring and they do tolerate pruning well. If you don't mind sacrificing flower buds, you can prune back stems when the shrub is dormant. Refer to our information on renewal pruning, https://extension.umd.edu/hgic/topics/pruning-shrubs-and-hedges#to
