My 20+ year old English Boxwoods are suddenly having a very difficult time....

Asked July 7, 2014, 2:33 PM EDT

My 20+ year old English Boxwoods are suddenly having a very difficult time. In the last month a 4 foot high one went from very green to very dead. It was in a protected area near the house. Others have had branch by branch die back. Are you aware of anything I can do to stop the problem ? Thanks, Dennis Gurtz (UMCP '68 and MBA '72).

First we need to diagnose the problem. Read through the diagnostic chart in our "IMP Series: Boxwood" to help you identify the symptoms and possible causes. Photos are included: http://extension.umd.edu/learn/ipm-series-boxwood-hg52

Also, be aware that a serious new boxwood disease, Boxwood Blight, has appeared in the U.S. and all boxwood owners need to be aware of the symptoms. Please look at the latest information on our website in the Invasive disease section: http://extension.umd.edu/hgic/invasives/invasive-diseases

When you get back to us, you can send us a digital photo of your boxwood (close ups of cankers or specific symptoms are helpful) attached to this email and our plant pathologist can look at it.
