Colocasia esculenta ... worth digging up for winter?
Planted a large Colocasia esculenta bulb in the ground, it came up in June and it grew well and large (for Ohio, far as i know), with leaves going up over 5 feet. It's about as big as I ever see in the area, got a lot of sun.
Could I dig up the ovoid tuber and would it grow at least as large next year? When would I dig it up? Cut off all the roots and stems? We are close to having a freeze. Do you store it in a pot with soil in a cool but not freezing place to overwinter?
Is it really worth digging up thou? Will it grow as large or larger? If it won't grow as large, I just won't bother and I'll buy a new one next year
