dusty plants

[paulz]

We have several plants in our garden that are & are getting covered in a whitey/grey dust. Is it some sort of fungus? can we do anything to get rid of it? It affects mostyly forget me nots, sweet peas & now two diff species of honeysuckle. If there is any treatment it needs to be child, dog & wildlife friendly please, thanks

It sounds as if it could be powdery mildew. Staff at your local garden centre should be able to advise you.
