Touch wood mine are ok so far. They were fine last year too
They need to have reasonable moisture at their roots in good soil, in my opinion, to avoid scabious mildew
No option but to cut the foliage down to the base and and spray with a fungicide thoroughly soaking the whole plant. Do,this on a dry day. Give it a day or so then feed and well.
If it's a continuos flowering variety it will start flowerimg again in a few weeks.
The solution, I,think, is not to let scabious dry out.
