Why does your Kalanchoe tomentosa have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Kalanchoe tomentosa is a succulent that requires well-draining soil; excessive moisture causes roots to suffocate and decay, leading to the rapid shedding of leaves. As the root system fails, it can no longer support the plant's foliage.
This species is sensitive to sudden drops in temperature, especially drafts from air conditioners or cold windows. A rapid change in environment triggers a stress response that results in leaf abscission.
While they prefer low humidity, extreme dehydration of the atmosphere can cause the fuzzy trichomes to dry out and the plant to shed leaves to conserve moisture. This is common in heated indoor environments during winter.
Small, white, cottony insects like mealybugs feed on the sap of Kalanchoe tomentosa, weakening the plant's vascular system. Severe infestations can cause the plant to drop leaves as it loses its ability to transport nutrients.
