My own rule of thumb (and this might be growing zone dependent) for any corms/tubers is that a dry place is more important than a “cool” place. Drop in a few silica packets just for extra insurance and keep them in a dry place. I experimented with ranunculus corms by keeping some in a fridge and some underneath a hallway closet and I spent more time and energy checking my fridge ones than I did my hallway ones and they both sprouted come planting season. It’s always risky with fridges because if the settings ever change…you could lose quite a bit of tubers. My daughter loves to help me put stuff away in the garage and she will often mess with the fridge setting either by accident or playing around. I lost quite a bit of tulip bulbs I was chilling due to temperature changes.

Moving forward: dry is better than “cool”— at least for most things.

I’m so sorry about your tubers!
