what do I do with my plant when its done blooming?
what do i do with my dahlia plant once it's done blooming? Do I dig up the tuber and store it when fall/winter comes, or do I just keep it in the ground the whole time?
I have about 6 dahlia plants growing, I don't know what kind. They are about 5.5 feet tall and have dark magenta blooms. I've never grown them before so I'm not sure what to do with them.
