How to care for a Christmas cactus:

1. Light: Place it in bright, indirect sunlight. Avoid direct sun exposure.
2. Temperature: Keep it in a cool room (around 60-70°F or 15-24°C) and away from drafts.
3. Watering: Water thoroughly when the top inch of soil is dry. Don’t let it sit in standing water.
4. Humidity: Provide some humidity, especially in dry indoor environments. Place a tray of water or mist occasionally.
5. Soil: Plant it in well-draining, slightly acidic soil mix.
6. Fertilization: Feed with a balanced, water-soluble fertilizer during the growing season (spring and summer).
7. Pruning: Trim to shape after blooming. Remove any dead or damaged segments.
8. Potting: Repot every 2-3 years in a slightly larger pot.
9. Bud formation: Encourage bud formation by providing 12-14 hours of darkness each night for 6 weeks in late fall.
10. Pest control: Watch for pests like mealybugs and treat them promptly if they appear.

With proper care, your Christmas cactus should bloom beautifully during the holiday season.
