Why does your Lilium OT Profundo 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 senescence of foliage, leading to sudden leaf drop. It often manifests as brown spots before the entire leaf detaches from the stem.
Lilium OT Profundo requires well-draining soil; excessive moisture causes Phytophthora or Pythium rot, which destroys the root system's ability to support foliage. As roots decay, the plant sheds leaves rapidly to conserve moisture.
As an Oriental hybrid, Profundo is sensitive to extreme temperature fluctuations. A sudden drop in night temperatures or a heatwave can trigger a stress response, causing the plant to abort foliage.
A lack of available nitrogen prevents the maintenance of chlorophyll, leading to chlorosis and eventual leaf abscission. This is common if the bulb has exhausted the nutrients in its immediate planting hole.
