Gastil: The larger bulb spring foliage species such as /L. sprengeri/ grow and flower well in 2 gallon tree pots which allow for deep root growth. Since these species generally take a season or two to recover from transplanting, you would need to have available refrigerator space for the whole pot (I suspect), though dormant bulbs can be removed from these pots with minimal root damage, so there could be room for experimentation with removing from the pot and refrigerating with minimal sphagnum or vermiculite in baggies. An exposed pot will dry out in a refrigerator, so, as long as you don't put it in the fridge waterlogged, it might be best to cover the top of the pot with a baggie secured with a rubber band. I've never had good flowering success of larger, spring foliage Lycoris, in standard pots, but a standard 7-gallon will be about as deep as a 2-gallon tree pot. Would need more bulbs in it, it would be very heavy, and would take up much more of your refrigerator space. Oh, and, to anybody in the naturally hardy zones, don't grow them in pots unless you are willing to store them in a cool place away from natural winter conditions. The bulbs will freeze unless you do this or plunge the pots (or reverse plunge, adding significant amounts of mulch to come up and around the entire pot). Mr. Kelly M.
