Dear Chad, What soil mix do you use and how much of the bulb is exposed? These both seem very appropriate for good culture. Best Jim W.

I don't give it any water in the winter time and water it about once a week during active growth. I try to let it dry out pretty good in between waterings. I like to use hydroponic fertilizer with most waterings, But sometimes I use a granular bulb fertilizer after which I skip the hydroponic stuff for awhile. I think patience is the main trick to get them to flower. :-) Chad In Elverta CA Zone 8ish( feels like 10 this winter!!) Sent from my iPhone Chad L.
