I have never had a hosta disease here in 20 years. So I looked it up. There is a disease called anthracnose that looks similar to your problem. It is a fungal condition best controlled to keeping the plants dry and giving them good air circulation, but there are some antifungal sprays that help.

An organic spray I found is 4 teaspoons of baking soda to a gallon of water sprayed on the leaves. It seems to work by changing the pH of the leaf surface.

I don't want to risk my other types of hostas so I'm going to dig up and destroy these. Thanks for the recipe. I'm sure that I will be able to use it on some other plants. I always prefer to use the natural cures such as this one. Thank you.
