Why does your Aloe dichotoma have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Aloe dichotoma is a succulent adapted to arid environments; excessive soil moisture prevents oxygen from reaching the roots, leading to fungal decay and chlorosis in the leaves. This is the most common cause of yellowing as the damaged roots can no longer transport water effectively.
In well-draining, rocky substrates used for Dichotoma, essential minerals like nitrogen can quickly leach away. A lack of nitrogen causes older leaves to turn pale yellow as the plant mobilizes nutrients to new growth.
While these plants crave intense light, a sudden move from shade to direct midday sun can cause localized tissue damage. This often manifests as yellow or bleached patches on the parts of the leaves most exposed to the sun.
Exposure to temperatures below 5°C (41°F) can cause cellular collapse in the fleshy leaves of the Branched Aloe. This physiological stress often manifests as a general yellowing or translucent appearance of the leaf tissue.
