The truck garage has become my "greenhouse" since the truck isn't in there for the winter.........we spend Nov-April in Texas. The ones in the pots I cut all the foliage off. The ones I dig I obviously cut the foliage. I also wash all the dirt off the bulbs and trim the roots. Those bulbs go on a pallet to keep them off the ground and I slide that under the boat. They can sleep there. LOL I think we keep the heat set at 55. My plants don't like it down there for the winter as there isn't a whole lot of light; I seem to have 2 or 3 that just look like crap in the spring and I toss them. Harsh, I know, but..........
