When it comes to festive plants, the Christmas Cactus and the Thanksgiving Cactus are popular choices for adding color and cheer during the holiday seasons. Although they look similar and belong to the same family, they have distinct care requirements that are important for enthusiasts and beginners alike to understand.
Overview of the Plants
The Christmas Cactus (Schlumbergera bridgessii) typically blooms in December, coinciding with Christmas, while the Thanksgiving Cactus (Schlumbergera truncata) blooms earlier, around late November. Their vibrant flowers range from red and pink to white and orange, making them attractive holiday decorations.
Light Requirements
Both cacti prefer bright, indirect light. However, the Christmas Cactus benefits from slightly more direct sunlight during the winter months to encourage blooming. The Thanksgiving Cactus thrives in filtered light and can suffer from too much direct sun, which may scorch its leaves.
Watering Needs
Proper watering is essential for healthy growth. During the active growing season, water thoroughly when the top inch of soil feels dry. Reduce watering after blooming and during dormancy. Overwatering can lead to root rot, especially in winter when the plant is not actively growing.
Care Tip:
- Use well-draining soil to prevent excess moisture.
- Ensure the pot has drainage holes.
Temperature and Humidity
Both cacti prefer temperatures between 60°F and 70°F (15°C – 21°C). They dislike cold drafts and sudden temperature drops. Higher humidity levels benefit the Thanksgiving Cactus more, as it originates from more humid environments, whereas the Christmas Cactus is more tolerant of drier air.
Fertilizer and Feeding
Feed the plants with a balanced, water-soluble fertilizer every month during the spring and summer. Reduce feeding during fall and winter, especially when the plant is not actively blooming. A fertilizer high in phosphorus promotes vibrant blooms.
Blooming and Rest Periods
The Christmas Cactus blooms in winter, often around Christmas, while the Thanksgiving Cactus blooms in late fall. To encourage blooming, provide 12-14 hours of darkness each night for about six weeks prior to the desired bloom time. Cooler temperatures also promote flowering.
Additional Care Tips
Both cacti benefit from pruning after blooming to maintain shape and encourage new growth. Use clean, sharp scissors to trim spent flowers and leggy stems. Repotting every 3-4 years helps refresh the soil and provides space for growth.
Summary of Care Differences
- Bloom Time: Christmas Cactus (December), Thanksgiving Cactus (Late November)
- Light: Christmas Cactus (more direct light), Thanksgiving Cactus (filtered light)
- Humidity: Thanksgiving Cactus prefers higher humidity
- Watering: Similar, but avoid overwatering in winter
- Temperature: Both prefer 60-70°F, but Thanksgiving Cactus tolerates slightly higher humidity
Understanding these differences helps ensure your holiday cacti stay healthy and vibrant, providing seasonal cheer year after year.
