East Coast Dahlias..anyone leave in the ground?
I'm new to dahlias, not new to gardening... I know here in the colder zones that it's typical to dig up the dahlias and store them over the winter.
But surfing through the forums yesterday I saw a post from a gal who I believe is in zone 6 and leaves hers in the ground, deeply planted vs digging them up. She said she loses a few here and there but that they also seem to multiply like crazy in the ground so it more than makes up for any losses. (It was a fertilizing thread, not a dahlia post so it was a lone comment)
This intrigues me because I would, of course, like to not have to overwinter. So, anyone else do that? If so, what do you do, how deep do you plant, do you mulch like crazy on top, etc. And if so, what are your typical results? Thanks!
