Calla Seedlings - What now?
A friend sent a few calla seeds to me last spring, and i sprouted them and tended through the season just like Arisaema seeds. They responded well to this. They just went dormant and I see on checking, that unlike arisaema, they still have large, fleshy roots. Do these need a colt treatment now, or just a rest? What should I do to them now? The tubers are about 3 cm diameter, and firm with the long fleshy roots.
