Hi all.
Have a delphinium as in picture, in a pot, in bright light all day but not direct sunlight.
Petals have gone white, almost like they have been bleached. Any help appreciated



They look like specks of mould on the petals of the dying-off flowers. The higher up flowers look OK - presumably they're opening later than the lower ones. I don't think there's anything you can or should do - nothing lasts forever, except plastic flowers.

This looks like Downy mildew, pale areas on upper leaf with gray/white even purplish patches underneath. We have had odd periods of cool/wet nights/and now warm humid days this year making it much worse.
From your picture I wnder if its an enclosed space? Delphiniums need space between them to encourage good air circulation and only water the soil to keep the foliage dry. If you have a really heavily affected plant its best to gee rid?
