    It's lichen. It isn't harming the plant so you can leave it unless the appearance offends you. I quite like it😊
    In London. Keen but lazy.

    It is just harmless lichen, no need to do anything. It shows that you live in an area with decent air quality.
  • Thanks for all your help, that makes life easier during my isolation. Kind regards

    If you're at a loose end during the lock down, there was a fascinating Gardeners' World on the subject of lichens   :D

    Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.

  • Thanks a lot I'll have a look
