How long does it take after pre-chilling for a bulb to come into flower? I need some flower stems in February, so if I pre-chill from now till mid-Dec, when am I likely to see blooms?

It varies. It really just depends on conditions. A good rule of thumb is to plan on 6 weeks from starting the bulbs. But if you need them on a certain date, I would start a few every week in succession, planning for 8-4 weeks.
