Even though I have brought my caladium into the house in a pot for winter, should I remove the bulbs from the dirt or is it ok to leave them in and just keep damp enough not to dry out over the winter, while they are in the house?
Is that significantly less than when it was warmer and they were in their prime? They are much easier to store dormant. A very warm house is needed to keep them going. You would want to let the pot dry out to store dormant in the pot. Keeping it moist could rot the bulbs. Start watering again when you see new growth poking up, and/or it's above 55 or so outside at night, and can go out in the warmth. Could be as late as late May. They survive here but don't start growing until then even though there will have been some near-90 degree days by then, and of course it's a lot cooler in MI generally. Once the pot dries well, you could put it in your basement if it stays above freezing. That's where I stored dormant tropical bulbs when I lived in OH. Putting the pot on a shelf or something to keep it off of the cold floor never hurts.
Thank you purpleinopp. I will quit watering even though there is still one leave still green on the plant. But it does look like new growth coming up on the bottom of the stem so will keep an eye on that one, before putting pot in cooler spot.
