What is Impatiens Downey Mildew? - 04/29/13

Did your impatiens bed look like it frosted last July or August with leaves and flowers wilted and perhaps noticed a white fuzzy growth on the undersides of the leaves? Then your impatiens fell victim to a disease called Impatiens Downy Mildew.

This disease only affects regular Impatiens including double impatiens, as well as a couple of wild species. Infection is spread by the wind and the spores are thought to over winter in the soil for several years.

It is recommended to use other plants for several years in order to increase your gardening success.

Plants that can be substituted for impatiens are: New Guinea Impatiens, Begonias, Torenia, Mimulus, Coleus, Pansies, Violas, Salvia, Calibrachoa, Fuchsia, Celosia, Ageratum, Alyssum, Dianthus, and Snap Dragons.
