Alternative Plants for Impatiens due to Impatiens Downy Mildew10/19/2012


If your impatiens bit the dust early last year, chances are they were hit with Impatiens Downy Mildew which plaqued many landscapes and gardens.  You would be well advised to avoid planting regular impatiens in the same location this year.  Although the plants coming from the growers and nurseries are healthy and free of the Impatiens Downy Mildew, the soil from last year will carry a strong risk of infection again this year.  Instead try some of the shade alternatives listed below.

If you attempt to replant impatiens, be on the look out for stippled leaves, leaves that turn downard from the leaf margin and white, downy-like growth on the underside of the affectived leaves.  Advanced symptoms include premature leaf and flower drop and plant collapse.  If you experience these symptoms, promptly remove the entire plant and lef debris.  Bag it immediately and put it in the trash.  Ideally this should be done before you notice the plant collapse entirely.
