Care Instructions
1. Light
Ideal Location: Place the plant in bright, indirect light. East-facing windows are ideal.
Avoid direct sunlight, which can cause leaf scorching, but ensure sufficient light for blooming.
2. Watering
Water when the top 1–2 inches of soil feel dry to the touch.
Use room-temperature water and avoid letting the plant sit in standing water.
Reduce watering in the weeks after blooming, as the plant enters a resting phase.
3. Temperature
Maintain temperatures between 60°F–70°F (15°C–21°C).
Avoid exposing the plant to drafts, extreme temperature changes, or heating vents.
4. Humidity
Christmas cacti thrive in 50–60% humidity.
To increase humidity:
Use a pebble tray with water (without the pot touching the water).
Group plants together to create a more humid microenvironment.
Use a humidifier in dry climates.
5. Soil
Use a well-draining, lightweight potting mix designed for succulents or cacti. Adding perlite or sand can improve drainage.
6. Fertilizer
Feed every 4–6 weeks with a balanced liquid houseplant fertilizer (20-20-20) during the growing season (spring and summer).
Stop fertilizing in late fall to prepare the plant for blooming.
7. Bloom Encouragement
To encourage blooming:
Dark Period: Provide 12–14 hours of uninterrupted darkness daily for 6 weeks in the fall (October to early November).
Cooler Temperatures: Maintain temperatures around 50°F–55°F (10°C–13°C) during this time.
Once buds form, return the plant to its usual location and resume regular care.
