Please help! The leaves of my delphiniums appear to have something whitish on them and are drying and curling at the edges and turning dark in places. Even the flowers have a similar deformation to them. Can someone identify what's wrong with them - and is it curable or should I remove them from my garden so they don't contaminate something else? (I have more pictures but couldn't figure out how to post more than one). Thanks in advance.
