why are the leaves falling off my christmas cactus

The falling of the leaves from your Christmas cactus is a natural process. Christmas cacti shed their leaves every year, typically in the fall and winter months, as a response to environmental changes, such as shorter days and cooler temperatures. This process helps the plant conserve energy and prepare for the dormant period. However, if the leaves are dropping at an excessive rate or the plant appears unhealthy, there could be an underlying issue, such as overwatering, underwatering, or nutrient deficiencies.
