I do not think there is much you can do to guarantee the bulbs will bloom Christmas. It sounds like you have done everything right just be patient. Since it is
growing I would continue to water you will get blooms eventually.
I see this question all the time "Why will my plant not bloom"? This has to be the most tortured bulb ever. LOL!!! Everyone seems to concentrate on putting it to sleep vs
growing the plant.
I would like to tell you what I do. It works! I always get blooms without fail.
My first bulb. Brought for 1.00 in Jan.
Jan - Potted bloomed in February.
Feb - April - After the
flower died continue to water and fertilize once a month.
May - after the last frost put outside in sun continue to fertilize and water.
Oct - when the first frost comes bring the pots in put in the window and water once a month.
My plants
flower every year from Dec - March.
That is my method. I hope it helps some see these beautiful blooms. I think if we concentrate on
growing the plant vs When to put it to sleep and when will I see a
flower, maybe a few bulbs will be saved from the trash.
A well grown bulb with lots of nurishment will
flower every year if you give it really good treatment it will bloom twice a year. One of mine bloomed in February and again in August this year. I found the more leaves I could get it to grow and keep
growing as long as possible the stronger the bulb was to give me more
flowers. Leaves feed the bulb.
