I grow mine in pots. I just cut mine back to ground level, drag them into the basement and forget them until about April, when I start watering them again. If I think of it, I do put a couple of cups of water on them during their storage.

I am in the same boat ,my greens i harvested around 20 small bulbs from one plant,the black ones I dug up the root ball but dont really know what to do with it , its huge !!I read some were to store in the fridge,

Will it hurt to allow them to keep growing inside? I have the big dark purple elephant ears , taro and malanga growing in pots. They are doing fine inside but am I screwing them up for next year when they go back outside?

If you store them in the fridge you will probably put them in permanent dormancy--in other words, dead. Some people seem to be successful storing them dry, others have said you need to keep them in a pot with a saucer beneath, and keep water in it. That's what I did until I found out they're hardy here--only not drought-resistant. I'm hoping they'll be back next year, but they are more sensitive to drying out too much than are alocasias. Sounds like storing them where they're not totally dried out and not too cold would be best.

Karyn, they should be fine inside, I have some in a pot that I just throw in the cold room and they are none the worse for wear in the spring.
