Why does your Abutilon pictum have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Abutilon pictum is highly sensitive to sudden changes in environment. Exposure to cold drafts from windows or air conditioning units can trigger an immediate physiological stress response resulting in leaf abscission.
Both overwatering and extreme underwatering can cause this species to shed leaves. Excessive moisture leads to root hypoxia in Abutilon, while dry soil causes the plant to drop foliage to conserve moisture.
As a species that prefers bright, indirect light, a sudden move to a much darker location can cause the plant to drop its older leaves as it fails to maintain photosynthetic efficiency.
Sucking insects like spider mites can deplete the sap of Abutilon pictum, causing enough physiological stress to trigger leaf drop. This is often accompanied by stippling on the leaf surface.
