Lilies of the Valley
I just got a few pips of this plant and some were much more "grown" than the others, so planting was a bit confusing. The instructions were to plant an inch deep, horizontally, and with the pips just breaking the surface of the soil. However, some of the pips had already seemed to be growing into a plant. I had one about 5 inches long so I just buried the root. However, now the "plant" is lying on the ground. Should I have buried the entire 5 inch growth? Please help. Thanks.
