Q.Canna lillies
My canna lillies are sick this year. I have them planted in the same place as last year. Last year they were beautiful and bloomed all summer till frost. This year they are stunted and have brown spots on the leaves which eventually die. Please help!

I believe your plants have Canna Mosaic Virus.
