A few years back, there was a fungal disease that totally wiped out all the impatiens. First they'd look droopy and the leaves would turn yellow, and then the plants would look 'cooked'. All the undersides of the leaves would be covered with a white mold. Every single plant died.
So the next two years I bought the New Guinea type of impatiens instead, as they weren't vulnerable to the disease. But they just didn't have the flowers and colours of the regular variety. So I was so very happy that some test plants did really well last year, and I went for them again big time this year. The plants were all doing really well....
Then to make matters even worse, I discovered signs of the white mold on several of my plants. My garden looked so beautiful too, and now it was doomed - if not from the beetles, then definitely from the mold. So I went out and took all kinds of photos, before everything is gone....
