Why does your Lily Oriental have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
This fungal pathogen thrives in humid conditions and can cause rapid foliage senescence and petal drop. It often begins with small brown spots that quickly coalesce, leading to the death of leaves.
Excessive moisture around the bulb causes rhizome and root decay, severing the plant's ability to support foliage. This leads to a sudden wilting and dropping of leaves as the vascular system fails.
Oriental lilies are sensitive to sudden heat waves or unexpected frost after bud development. Rapid shifts in temperature trigger a stress response that forces the plant to shed leaves to conserve energy.
High populations of spider mites pierce the leaf cells to feed on sap, causing rapid chlorosis and premature leaf drop. This is particularly common in dry, hot environments where lilies are grown.
