Why does your Aeonium arboreum Atropurpureum have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Aeoniums are succulents that store water in their leaves; excessive moisture leads to oxygen deprivation in the soil, causing roots to decay and yellowing the foliage. This is the most common cause of leaf discoloration in Aeonium arboreum.
A lack of available nitrogen prevents the plant from producing chlorophyll, leading to a pale yellow appearance in older leaves first. This often occurs if the potting medium has become depleted over time.
Extreme temperatures can shock the plant's metabolism. Intense summer heat can cause yellowing/bleaching in the 'Atropurpureum' cultivar, while sudden frost can damage cell walls, leading to yellow, limp leaves.
While Aeoniums love sun, insufficient light can cause the plant to lose its deep purple pigment and turn a sickly yellow-green as it struggles to photosynthesize effectively.
