2. Control the Light
Christmas cacti are short-day plants, meaning they need long nights (about 12–14 hours of darkness) to form flower buds.
How to do it:
Move your cactus to a dark room or cover it with a light cloth or box from evening to morning for about 4–6 weeks.
During the day, place it in bright, indirect light.
Once you notice tiny buds forming, return it to its normal location and resume regular watering.
3. Avoid Sudden Changes
Christmas cacti are sensitive to sudden environmental changes. Once buds appear, avoid moving the plant, as this can cause the buds to drop. Keep the light, temperature, and watering consistent.
Extra care tip: Avoid placing it near heaters, cold drafts, or direct sunlight.
