Impatiens dying

Asked May 13, 2018, 10:43 AM EDT

I have planted impatiens for years along a fence in my shady backyard. Last year, they started to wither and finally die en masse mid season. Is there a reason for this?

Your impatiens likely have downy mildew. It is a disease that plants come infected with. Once planted it resides in your soil and will be there for years. You will need to plant another variety of plant in that area. I have attached a link below to an article about downy mildew. It gives some alternative plants you can use in the area. https://www.extension.umn.edu/garden/yard-garden/flowers/managing-impatiens-downy-mildew-in-landscape/

Thank you for your response. I was afraid of this. My plants looked exactly like the ones in the article. :-/
