They do like strong light. As they are growing in deciduous forest, increasing the light intensity during winter tends to result in more flower production. My plant is sitting right in front of the south-facing balcony window and enjoys bright sunlight only filtered through the double-pane insulation window which, by the specification in the glass maker's catalog,should pass about 70% of the total sunlight through.
It is currently mounted on a slab of oak bark--I water daily during the spring and autumn; during the summer, I water twice daily, at the morning and the evening after I got from the work. Around December, I gradually reduce watering to the point of twice a week. During the winter, the bulbs will shrivel but it is no cause for an alarm....as the bulbs will swell up as soon as the flower bud formation kicks in, usually during February. During the growing seasons I give it some water-soluble fertilizer every week, until October. This one was a reliable bloomer for me, sending out spikes every February and blooming in March. The flower lasts for two weeks, which is somewhat remarkable for the section known for short flower life-span.
