My Aquilegia (different Varieties) and numerous other plants ie: Delphinium, Hollyhock have produced leaves with a grey/white appearance this year.The delphiniums are on their second spurt but, although they begin their growth quite healthily the leaves turn to the white/grey. they are all positioned in different parts of the garden.Is this a fungus of some sort? I have used a good fungal spray,but perhaps too late. My question is, is there anything I can add to the soil to prevent this?
