How to Check for Disease in Impatiens

It’s not always you, it might be a disease!

So, you’ve done everything you can to make sure this year’s impatiens garden will do its best. But no matter what you do, your impatiens don’t look so great – or even worse, they’re doomed! Don’t blame the gardener. It’s most likely Impatiens downy mildew (IDM) that was the culprit.

Checking for Impatiens Downy Mildew

IDM is a serious disease in the United States. In recent years, it has limited the use of impatiens in gardens, containers, and flower pots. IDM is caused by a fungus-like water mold called Plasmopara destructor. To be sure your plants are free of this disease, follow these few steps.

- Early symptoms can be seen on leaves near the tips of branches and include an irregular yellow-green discoloration.

- You’ll want to look for its most distinctive characteristic. The best way to do this is to turn over a leaf or two to check for white fuzz.

- This fuzzy white material develops on the undersides of leaves in impatiens plants.

- Check for this on stems and buds, as well.
