Minimum temp to start Colocasia into growth?

Hi. I left some Colocasia esculenta to overwinter under a thick layer of mulch in my garden. The tubers seem to be still firm. I'm hoping they'll sprout again, but I'm wondering if they need warm temperatures to do so. They're planted in a fairly shady spot in heavy soil, so I can't rely on the sun warming them up much. Will they come up by themselves, or should I dig them up and start them in heat? It's quite mild here for the time of year, around 20C (68F) during the day.
