Why does your Lily Rio de Janeiro have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
As a cultivar of Hippeastrum, sudden drops in ambient temperature or exposure to drafts can trigger an emergency response, causing the plant to shed leaves to conserve energy.
Excessive moisture in the bulb's substrate leads to anaerobic conditions and fungal pathogens like Fusarium, which compromise the root system and cause foliage to detach.
A sudden change in light intensity, such as moving the plant into a much darker corner, can cause the lily to drop leaves as it cannot sustain its current photosynthetic rate.
Sucking insects can deplete the plant's vascular fluids rapidly; if the infestation is severe enough, the lily may drop leaves to mitigate further fluid loss.
