I did this with daffodil bulbs that were dug up from my mother in laws garden, I put them all together in our garage in a corner in a bucket, all together, planted them the next spring and it was great, almost all took and flowered, stays above 35 degrees in the garage, closest to the house. Hope this helps, also used sawdust and a lined dog food bag one year, that worked good too.
