I store mine in a warm garage with artificial grow lights on the ceiling (about 12 hrs on/off) in the original pots. Just enough water to keep the alive and they do beautifully. In the spring , I either leave them in the pots or transplant them to the ground. In the latter situation, they are a little slow to get going but in a month or so they go "bananas". I get new plants every year that I can grow independently and don't remember losing any over the last 5 winters since I started using this method.I go for simplicity of care . I have tried storing the bulbs dry , keeping them in pots and cutting the leaves off over the winter but the way I do it now works best for me.
Experiment and see what works for you.
