Leaves of dhalias blotches with yellow, plant otherwise looks healthy. However, If it’s mosaic virus I know I should destroy the plant. Any thoughts? Thanks

Thank you for your question. I see no indication of the virus in your plant’s leaves. They may be experiencing a nutrient deficiency (especially nitrogen) instead. Can you bring leaves into an Extension office? Here are 3 close by with addresses and hours: https://extension.oregonstate.edu/mg/metro/have-gardening-question Good luck!
