Pests
Christmas cacti are relatively pest-resistant but can occasionally suffer from:
- Mealybugs: Appear as white, cottony masses in segment joints
- Treatment: Remove with a cotton swab dipped in rubbing alcohol and treat with insecticidal soap
- Spider mites: Cause stippling on stems and fine webbing
- Treatment: Increase humidity and treat with insecticidal soap or neem oil
- Fungus gnats: Small flying insects that indicate overly wet soil
- Treatment: Allow soil to dry thoroughly between waterings and consider repotting if infestation is severe
Diseases
- Root rot: Caused by overwatering or poor drainage
- Prevention: Proper watering practices and well-draining soil
- Treatment: Remove affected parts, repot in fresh soil, reduce watering
- Stem rot: Soft, discolored segments that may fall off
- Prevention: Avoid water sitting on stems and maintain good air circulation
- Treatment: Remove affected segments and adjust care conditions
Environmental Issues
- Limp or wrinkled stems: Usually indicates underwatering
- Solution: Increase watering frequency slightly
- Reddish stems: Often a response to intense light or nutrient deficiency
- Solution: Move to a more appropriate light level or adjust fertilization
- Yellowing segments: Can indicate overwatering, poor drainage, or too much sun
- Solution: Adjust watering schedule, improve drainage, or relocate the plant

FAQs About Christmas Cactus Care
Q: Why are the buds falling off my Christmas cactus? A: Bud drop is usually caused by environmental stress such as sudden temperature changes, drafts, dry air, or inconsistent watering. Keep your plant in a stable environment once buds form.
Q: Can I place my Christmas cactus outside? A: Yes, Christmas cacti benefit from spending summer outdoors in a shaded location when temperatures are reliably above 50°F (10°C). Just be sure to bring them inside before temperatures drop in fall.
Q: How do I know if my holiday cactus is actually a Christmas, Thanksgiving, or Easter cactus? A: Look at the stem segments: Christmas cacti have rounded, scalloped edges; Thanksgiving cacti have pointed, claw-like projections; and Easter cacti have rounded edges with small bristles and star-shaped flowers.
Q: Why isn’t my mature Christmas cactus blooming? A: Your plant may need a more defined period of shorter daylight and cooler temperatures to trigger bud formation. Try placing it in a room where lights aren’t turned on in the evening, ensuring it gets 12-14 hours of darkness daily for 6-8 weeks before expected bloom time.
Q: How often should I repot my Christmas cactus? A: Christmas cacti prefer to be slightly root-bound and typically only need repotting every 2-3 years. The best time to repot is shortly after flowering has finished.
