Petunias Dying


There seems to be a problem with my Petunia Hanging baskets and I cannot work out what the issue is and the cause.

Looking at websites its looks to be Mildew or Grey Mould?

I've noticed a lot of buds that are wet and deformed and brown, and have removed these.

Can someone look at the pictures to see if I am right and if so, how can I treat it, trouble is I do not want to harm bees.  There is greenfly on my first basket, I bought ladybirds but they all flew away :/

Any advice would really be appreciated.

Thanks in advance.

    Mildew I'm afraid - they are susceptible to it. The mildewd bits will die, so you can cut them back to non-mildewed bits if there are any and if you can keep it reasonably moist and fed, it may come back

    BTW the droopy flowers just need removing - there is nothing wrong there

    I'm coming to the conclusion that petunias are more trouble than they're worth.

     I've already promised myself to grow  Calibrachoa instead next year
