Can you help me plant my dahlias?
I am new to dahlias, and to bulbs, really. I just got my order of purple creme de cassis dahlias, but no directions came with it. How deep and how far apart do I plant them? Which end is up? The label says they will be 36" tall. Is this accurate info? Will they bloom all summer, or just once? Will I have to stake these flowers? I live just north of the Dallas area and they will be planted where they get lots of sun. Thanks!
