Mine bloom every year around Christmas or just after in January. I grow them in clay pots and they are completely dry all summer. I water only when I see growth start around the beginning of November. They are in a greenhouse kept at about 60 degrees F. I feed them weakly every time I water with a basic flower mixed fertilizer. I also separate the offsets about every 2-3 years. Offsets bloom in about two years if they are small and the next ear if they are fatter. Ill attach a photo of the main pot.
