Growing Parma Violets
Does anyone have helpful hints for growing Parma Violets in pots or the garden? Sometimes my healthy looking plants develop crumpled leaves and look miserable. On close inspection I have found aphids infesting the crowns and under the leaves; doing a lot of damage. Pyrethrum spray is effective in getting rid of them but, in time, they come back. The little blighters even crawl into the flowers. I didn't know they were there until I enlarged the pic: Aphids on V.parma 'Lady Hume Campbell'which I have posted here.
