Actually Jack, this is easy, not fussy and almost worry free. I do a lot of rotation of first in-first out commercial stuff every year in my front gardens as well as culling and replanting my hybrid selections every two years. See that cardboard box you have them in already? Use it. I would cover them with moist garden soil straight from the garden if you have soft loamy soil. If not use potting mix to cover them. Do not water and store in a cool dry area away from sun and rain. I typically store bulbs up to 3 to 4 weeks if necessary with ordinary Fall temperatures without any problem whatsoever. The main worry is rodents so be mindful of that.
You said you were going to plant the large bulbs first. Just food for thought. I actually prefer the smaller/medium size younger bulbs because they have the vigor of youth and disease resistance and they just seem to adjust better. I give away the larger older bulbs.
Well, that's how I do it. But I'm getting old, lazy and careless due to too much experience over the years and tend to take short cuts that only I can get away with. I'd love to hear the suggestions of others.
