Talkback: Plant diseases and busy Lizzies

is it because we are inporting more plants and the movement of people round the world.we are no longer confined to area and this makes for viruses to spread.


  • Hi Flowering Rose. Many plant diseases have been 'imported' or have spread to the British Isles in the, including devastating tree diseases.

    Downy mildew is a fungus disease, but virus ones can also spread easily in different ways.

    I'm not sure where this particular disease came from, but it certainly spread quickly! All we can do is avoid growing problem plants and choose resistant ones instead.
