I planted my hostas about 3 weeks ago. I purchased them from a local nursery. They all had a healthy appearance until the last few days. They have developed light colored spots along with some dark spots. Can you tell me how to treat it please?
Spots on My Hosta Plants

I believe you host is infected with a virus.
I have listed a link that gives more information.
Since this can spread easily to other plants I would personally remove them from my garden.
I would contact the nursery it was purchased from and request a replacement. Most reputable garden centers will stand behind their product.
