Caladiums loves humid heat. That has been the drawback on my side..we get too much dry heat during the long dry months..so got to have them on the brightest side of the garden from mid Spring to Fall, but not under our direct sun. And once awake, got to keep them well watered.
Winter is doldrums time..so it all depends on your outside environment if it is suitably warm enough later in Spring. I usually bring out my overwintered plants when overnight temps show 50F and higher. With Caladiums, may need higher..70F and higher.
