Why does your Lilium OT Revelation have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
Fungal pathogens thrive in high humidity and can cause rapid tissue death, leading the plant to shed leaves as it attempts to isolate infected areas. This often starts with brown spots that expand quickly across the foliage.
Overwatering or poor drainage in lily bulbs causes oxygen deprivation, leading to decaying roots that can no longer support foliage. As the root system fails, the plant undergoes rapid senescence and leaf drop.
Sudden shifts in temperature or extreme dry spells cause lilies to enter a defensive dormant state to preserve the bulb. Rapid evaporation from leaf surfaces during heatwaves can trigger immediate shedding.
A lack of available nitrogen prevents the plant from maintaining chlorophyll and structural integrity in the leaves. While usually gradual, severe deficiency in established lilies can lead to yellowing followed by sudden drop.
