    I'm so :gaah::wallbanging: flipping angry! :mute:
    Yes it's been warmish and humid but we had none stop drizzle for a week :scratch: (ok humid :redface:)

    Anyhow, maybe I could have watered more :dunno: or maybe it's just ' one of those things?'
    Ultimately I'm not a happy gardener tonight :mute:

    I'm posting this so that , hopefully, my fellow gardeners can suggest ways to deal with and or prevent this problem, not only for me but anyone else having this problem this year :)

    Please tell me I don't have to remove all offenders? :cry3:

      @Loki sorry to hear it mate and it calls for more experts on it, as that's one thing I've never had to deal with :)
      You shouldn't need to water anyway if you've had drizzle through the week, unless it's only been bits and dabs then your plants would need water :)

        Overhead watering in hot humid conditions only adds to the problem of mildew to those susceptible plants. Non stop drizzle merely does the same if the ground is dry

        I consider a couple of points when dealing with mildew; susceptible varieties are avoided.
        Many asters are martyrs to mildew yet others are resistant to it so choose the latter. Frikartii Monch never suffers from it, for example..

        Second, the soil. It needs to be moisture holding. Adding bulky matter at planting time and mulching helps ward off mildew. Forget growing susceptible plants in dry sandy soil for example

        Third, I cut back vulnerable plants like some scabious in mid summer or before if its esp hot. Cut back hard, fed and watered they respond, I find, by growing back without further mildew problems :)

          I read that milk spray prevents mildew on cucumbers and courgettes so I sprayed my courgettes leaves with it at the weekend. Every year they get mildew so I thought I’d try prevention this year rather than cure.

            Peter I've had plants in the home in the past where to keep the leaves nice I used to get a clean duster and wipe them with milk and it kept them nice and healthy :)

              @Loki what plants are affected? Tomatoes/Cucumbers or Ornamentals? You can apply chemicals to Ornamentals like roses etc but if it's edible crops you need something safer.

                Never come across mildew this early myself.
                But as most chemicals are now banned the only thing that does seem to have an effect is diluted milk.
                But I dont think it lasts long, watering might help though, as dry roots is a big factor.

                  Only solution is to remove affected foliage, clean up around base, mulch and water:)

                    @JWK plants affected are lupins, knautia, sweet peas and one I don't know the name of :redface:
                    The greenhouse and veggie patch are all ok :)
                    Thanks for all the advice :dbgrtmb: I've been out tonight and gave everything a good soaking.
                    :ThankYou:

                        Here's a picture of the ' unknown ' plant :frown:
                        I think this is where the problem stemmed from, I had lots of pots grouped closely together :doh:it seems to have spread to the border and other pots :dunno:
                        I thought the plant was a Veronica or similar, any advice on ID or suseptability would be very much appreciated :blue thumb:

                          Loki, in a container veronicas are extra susceptible to mildew. Too dry :)
