How to Encourage Blooming in Thanksgiving Cactus?
To encourage blooming, provide the plant with a period of darkness for 12-14 hours daily for about six weeks before its blooming season. Additionally, avoid moving the plant during this time to prevent bud drop.
Common Problems and Solutions
Here are some common issues with Thanksgiving cacti and how to solve them:
- Yellow Leaves: Caused by overwatering or poor drainage. Adjust your watering schedule and use well-draining soil.
- Bud Drop: Often due to sudden changes in light or temperature. Keep conditions stable during the blooming phase.
