Welcome to this site, hope you enjoy it. We don't always get to plant 'per instructions.' Since you have quite a few corms, you may want to try a couple different methods. Plant some directly where you want them, and keep them watered until your weather changes. Store others in sawdust or whatever else you want to use to keep them protected and plant out in the spring. Maybe plant some more in pots you can move around to take advantage of sun/rain/wind protection. Are they currently blooming or no? I'm in Zone 8 and mine are done blooming, have gone to seed, and the foliage is turning brown for winter. I think I've moved some in the fall before (I have several clumps) and also in spring. Play around with them. Do you know the cultivar? Be forewarned that the taller ones (Lucifer) eventually need quite a bit of space and tend to sprawl unless they either have some support or companion plants to help hold them up. I think they look spectacular when allowed to grow into their large vase shape rather than trying to make them 'behave' in a smaller space than they really need. Good luck!
