Hello,

I've lost three dahlia plants this past week. The plants suddenly wilted and when the stem was gently pulled out of the ground I discovered the once fleshy and healthy tuber was practically devoured. I'm getting concerned it will continue and affect the whole row. One was planted in a nearby bed. I don't know if I'm dealing with a borer, maggot or a wilt or ??? I did notice a nearby parsley plant suddenly die the same way. No problems like this last year in the same bed with the dahlias. Any suggestions on what's going on and how I can save the remaining dahlias? Thank you for your time.
