I grow lycoris, but not in a cold zone. What I know about lycoris is that it does not like to be moved. Moving delays flowers (but not the green) for up to 2 years.The green leaves ( looks like liriope) come up after the flower (September) and stay until the next June. The leaves disappear over summer, by then they they have fed the bulb. I think planting and lifting would not yield the results you would want. How about planting it in a pot? The pot could be placed where it would not freeze. Hopefully someone in your area could have more ideas.Have a joyful day and sorry I could not have helped more.
