    Hi,

     I have a Viburnum x Carlcephalum, planted last summer, which seemed to be doing very well (apart from some aphid infestation at times), but toward the end of winter has now got patches of peeling bark, on the base and on some of the main trunks. Underneath the wood is dark brown/black. There are still a few leaves left on it (it held onto its leaves late and they didn't show very bright autumn colours, but rather just fell off).

     Is this a disease of some kind? I have done some searches on the web, and Botryosphaeria seems to be the most likely, though I(thought) I kept the plant well watered and mulched. I'm not aware of any injuries that it may have received, and I haven't pruned it. 

     Here are some pictures:

    Does anyone recognise these symptoms? Is it treatable?

     Thanks for any help,

     Cam

    Hi, unfortunately your viburnum looks like it is a lost cause due to some sort of disease attack. Possibilities are Honey Fungus or Sudden Oak Death. See links: Blackstart https://www.rhs.org.uk/advice/profile?pid=180 https://www.rhs.org.uk/advice/profile?PID=329

    Thanks for the reply. Phytophthora looks particularly serious, as I have to contact the Forestry Commission. I will check and see if there are further signs of either disease.

     Kind regards,
