As far as possible you want to replicate the conditions the lilies would experience in the ground. As noted above, Before winter, add 4 to 6 inches of mulch, simply to delay the ground freeze and allow the roots to keep growing. Leave the mulch until spring once the last hard frost has passed. See your local . If your ot is not deep enough to allow that much mulch, you could put the pot into something else that would facilitate that (from a box to the ground). Also above it says Keep moist in winter. How much depends on local conditions. Adequate mulch should keep the 鈥渕oisture鈥 from freezing. Speaking of freezing, a too shallow container (or bulb depth in ground) can result in frost heaves (essentially freezing and thawing cycles) in the soil that can lift the bulbs and expose them more than is desirable. Rain, followed by dryness, then rain again can also contribute.
Alternatively, we often recommend lifting the bulb, storing it in a cool, dry place in peat moss that you occasionally dampen, then replanting it in spring.
