I was given an elephant garlic bulb a few weeks ago, but haven't planted it yet. Is it too late? It's a nice solid round bulb about 1" in diameter, not subdivided into cloves. Could I plant it in a pot for the winter and transplant it in the spring when I know whether I'll be keeping my allotment plot? If so, how big a pot? How deep should I plant it. Should I sink the pot in the soil or keep it in a drier area?
