When to plant dwarf dahlia tubers in zone 4?
Do they need to wait until the soil is warm, or plant as soon as it
thaws and nights are usually above freezing? Or do they need to be
started indoors in pots, then set out like tender annuals?
I almost bought a dozen bedding dahlias at Sam's Club today, but then
thought it might be too early. I know they are day-length sensitive;
that's why I've never tried starting 'em from seeds (days are long while
it's still cold up here)
Thanks,
Bob, in southern MN
