Impatiens Downy Mildew Strikes Close to Home

It's all well and good to read about a new disease that is sweeping the nation, but when it hits close to home is when you start to really pay attention.

Several articles have been written in the Horticulture and Home Pest News about Impatiens Downy Mildew.  See HHPN June 27, 2012 and HHPN August 29, 2012.

The photo below is from my front yard earlier this summer.  The impatiens went from beautiful, lush and colorful to straggly stems in 3 days.  They look even worse now!  

I should have paid more attention to my colleagues and avoided those inexpensive 6-packs of pretty impatiens transplants.  Lesson learned!
