Why does your Kalanchoe daigremontiana have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Kalanchoe daigremontiana are succulents that store water in their fleshy leaves; excessive moisture causes the roots to suffocate and decay, leading to chlorosis (yellowing) of the lower leaves. As the root system fails, it can no longer transport nutrients effectively.
A lack of nitrogen prevents the plant from producing sufficient chlorophyll, resulting in a pale yellow appearance that typically starts with older, bottom leaves. This often occurs if the soil has been depleted of minerals over several growing seasons.
While this species thrives in bright light, extreme shade can cause the plant to lose its deep green pigment and turn a sickly yellow as photosynthesis slows down. The leaves may also become thinner and more elongated (etiolation) alongside the color change.
Kalanchoe daigremontiana are tropical succulents and cannot tolerate frost or sudden cold snaps. Exposure to temperatures below 50°F (10°C) can damage cell walls, causing the leaves to turn yellow and eventually translucent.
