Q.How can i grow impatiens after the fungus outbreak
A couple years ago they said a fungus was killing the impatiens after they got started blooming. Haven’t planted any since. How can I grow impatiens after the fungus outbreak?
There are a couple of diseases which have seriously threatened the impatiens crops in recent years. Here is a link to an article about the powdery mildew disease: https://www.gardeningknowhow.com/ornamental/foliage/ornamental-grass/no-plumes-on-ornamental-grass.htm
and here is one to the Necrotic Spot Virus: https://extension.psu.edu/pests/plant-diseases/all-fact-sheets/impatiens-necrotic-spot-virus
These diseases are epidemic, despite the growers attempts to breed resistant strains of impatiens. Probably your best bet is to use alternative flowers: http://extension.umd.edu/learn/alternatives-garden-impatiens-because-downy-mildew-disease
