Aquilegia 'Nora Barlow'. I have grown about 30 of these plants from seed collected from the original plant in my garden. They are outdoors in a plastic grow-house, this is opened daily for ventilation.Today I notice some of them have a grey 'film' on their leaves. If this is grey mould, how do I prevent it ruining the plants please?
