Protect the dark period
Artificial room light late at night can interrupt the long nights holiday cacti use to initiate flowers.
Keep fall conditions cooler
Cool nights help encourage bud formation. A consistently hot room can work against flowering.
Do not move budding plants constantly
Major changes in temperature, light and placement can contribute to bud drop.
FAQ
Can I force a Christmas cactus to bloom immediately?
