    I need advice about apple trees. My dwarf apple trees have developed some sort of disease. There is a white power-like substance on the leaves and bark. I have taken some photos that may help identify this (if I can upload them) . Any help or advice on how to treat would be appreciated, I don't want to lose these trees.

    It looks like Woolly Aphids but I've no experience of dealing with them.

    Spray the blighters with washing up liquid diluted with water, slightly more concentrated than you might use for the dishes - if you don't want to use chemicals. It causes the aphids to explode :eek:

    Wooly aphids can be the trickiest of all aphids to get rid of. That white powdery substance coating them acts as a barrier against almost everything. The washing up liquid might do it.
    If it doesnt, try SB Plant Invigorator mixed in the sprayer with a normal pesticide. The SB is a biocide and is completely safe to use. It breaks down the protective coating on the aphids allowing the pesticide to kill them quickly.
    Hope this helps!
