Why does your Aloe polyphylla have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Aloe polyphylla is native to high-altitude, well-drained environments; excessive moisture causes the roots to suffocate, leading to chlorosis (yellowing) as the plant can no longer transport nutrients.
In the specific mineral-rich mountain soils this species requires, a lack of nitrogen can cause older leaves to turn pale yellow before progressing upward through the spiral.
This species is highly sensitive to temperature extremes; sudden heatwaves can cause leaf bleaching/yellowing, while frost damage can trigger rapid chlorosis in the spiral structure.
While they need bright light, too much direct, intense afternoon sun without adequate humidity can cause the leaves to yellow and eventually scorch.
