crispy black edges to some of my plants' new leaves

My dwarf acer, bay tree (in pot), one clematis and a lavender all seem to have a problem with new leaves - whilst the plants are still thriving in themselves at least for the moment, most of the new leaves have developed black edges which are crispy to the touch - when you handle them, these edges of the leaf just powder away in my fingers. I should imagine this won't be great news if it continues. Help - is this possible wind damage or a disease?

    Wind damage- it has appeared- on my bedding salvias and nasturiums in the last couple of days-they should grow out of it


  • thanks - what a relief! when the sun ever does shine again, we'll be able to see some improvement, I hopeimage

    I haven't got crispy black edges but my bay tree (bush) has the worse case of sooty mould I've ever seen.   It was fine last year, bit of scale insect but not a major problem.   This year, looks like it's been down the pit!   So I chopped the tops off yesterday, left the three main stems with two sprouting leaf nodes each.   So now it has two chances!

  • does sooty mould only affect the edges or the whole leaf, Auntie?

    This is just confusinng the issue-you have not got sooty mould-that is a fungus disease-this is an image of sooty mould

    Geoff's right - sooty mould is a fungus that grows on the sugar excreted by scale insect. Get rid of the scale insect, clean the tree and it'll be fine. Nothing like wind damage.
