    Can anyone advise me what to to. I have a glorious red japanese maple in a large container. I noticed that the leaves are wilting and curled up. There is also a nasty looking fungus on the trunk. It is like white circular scales with a brown dot on top

    What can I buy to kill this off?

    Any advice appreciated

    any photos?
    it's possible that the fungus is not just sitting on top of the trunk - may have affected the tree itself, which would make killing the fungus a lot harder.

    Photos would be good but it sounds like horse chestnut scale for the trunk issue. You can either scrape off the scale or treat with and insecticide containing deltamethrin. The insect lives off the sap but does not damage the tree.

    The wilting leaves could be because of sun scorch or more like wind damage.
    Were the leaves ok last autumn?

    Again, a photo would be great to see.

    Yes it is most definitely that scale. . The leaves are usually lovely and it is in a sheltered location. Maybe when I scrape off the scale I will feed the plant up a bit and it might perk up.
    Thanks
