I ordered a Amorphophallus Konjac in October of 2009. I recieved my bulb and put it in a pot using a buld mix soil. Left it sitting in my window where it gets bright, warm light. I now have a sprout of about a half inch. When do I start watering it and what do I do when it starts getting cold. I live in Maryland and I haven't put it outside at all. Like I said, it's been in a pot in my window. Do I take it out of the soil in the fall and store it over the winter or can I leave it in it's pot in the window?
