Were do things like Cannas and Dahlias belong? They are not really bulbs. But I just started mine today.
Most years I simply plant them inground. Much later than this time of year actually. But I get very poor results with many never coming up. This year I just bought two packages locally with two roots each, Tangelo and Black Knight. I decided to pot them which is what I did. I will keep them inside were its warm (not too warm) until they sprout and them bring them outside to harden off. Then when its warm enough I will plant them. By that time I will actually have plants. That is if all goes acording to plan.
In fact last year I was so mad at the poor rate of success I got the prior year that I never ever planted any. But I like them so I miss them so am trying this new method this year.
