My Mom has never had much luck getting Amaryllis to bloom a second time. They don't survive outside here, there are issues with finding a spot in the house they get enough light, storage issues, etc. We have an unheated sunroom/greenhouse that never quite gets below freezing...but gets cold enough to use as a fridge on Thanksgiving.

We dumped some big potted bulbs there last year...Amaryllis I think, but I'm not sure. I just visited and noticed they each had two tall leaves. I'm unsure if they have ever been dormant (possibly they were February of last year?) and even unsure of the species (but I think Amaryllis)

What do I do with them? Ideally I'd want them to bloom for Thanksgiving or Christmas, but I'd be happy with getting any second bloom out of them. The Sunroom is just getting cold for the year...do I cut off the leaves and leave them there until Thanksgiving do induce dormancy? Do I bring them in where it is warm?
