Over Wintering Colocasia
I grew my first Colocasia this past summer, and it was beautiful. Now, we're getting light frosts at night and it's time to start thinking about winter storage.
I do not have the room to move the giant pot indoors, so I would like to un-pot the corm and store it. I'm in zone 5b, and the Colocasia is growing inside an unheated greenhouse in a very large terra cotta pot.
How should I proceed? When should I dig the corm? It still has several large green leaves growing. Also, my home is extremely dry. Should I worry that the corm will dry out too much over winter?
What is the proper procedure for storing Colocasia bulbs in northern zones over winter? There's a lot of conflicting information floating around.
