I planted Calla bullbs (tubers) two weeks ago in pots since it is too cold to start them in the ground. I read various forums about which direction to place the bulbs in the soil. The bulbs are in the shape of a small but fat cooky and hence only have two sides. Some said place the rounded side up. Both sides look rounded to me. Another said to plant the "ears" up. Mine have no up, there are 2-4 dispersed around the edge. Picture a fat round cooky with some large bits around the edge. Some say to have the crinkled side up. Both sides look crinkly to me. So I planted them and am waiting but did I do the planting correctly?
The only truly distinguishing feature is a dark circular brown spot(actually a series of brown rings) on one of the two sides. On one or two bulbs a small shoot is coming out of the center of this and I took this to be a root so I planted the dark ringed spot downward.
I just looked at a planting and some thin white tendrils are coming out of the side I called the bottom. Are these the roots or are these the stems?
I would appreciate any thoughts on this and if you're in the business have better instructions for us, the unknowing. Thanks
