why are buds falling off christmas cactus

The Christmas cactus is a tropical plant that typically sheds leaves or buds during winter months, even when kept in optimal conditions. This is a natural process known as "bud drop," which occurs in response to reduced light levels or temperature changes. To prevent bud drop, try increasing the light levels in the environment and maintaining a consistent temperature. Additionally, avoid exposing the plant to drastic changes in temperature or humidity, as this can trigger bud drop. Water the plant regularly, but make sure the soil is well-drained and not too wet.
