I am also interested in overwintering alocasias in pots this winter.
I am in zone 8b. I bought an imperial red alocasia mid season and a regal shield late in the season. My long term plan is to plant them in the ground each spring and dig them up late fall early winter. I am under the impression they should not be left in the ground in zone 8b.
Since I bought them mid and late season, I didn't want to plant mid and late summer, just to dig up again in the fall. Also, I was hoping they might put out pups if I overwintered them as houseplants and then I would have more to plant in the spring. So I have moved them into the house.
While growth has definitely slowed since the days have gotten shorter, I am hoping they will not go dormant over the winter as houseplants. My imperial red has a very slow growing pup that is putting out it's second leaf. The regal shield has 2 spadex(?). I have already gifted one of the pups of that plant.
