Why does your Lily Cold Play have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
This fungal pathogen thrives in high humidity and can cause rapid tissue death, leading to the sudden dropping of foliage. It often starts with brown spots that quickly spread across the lily leaves.
Lilies are susceptible to bulb rot if the soil remains saturated, which disrupts the transport of nutrients to the leaves. When roots decay, the plant cannot support its foliage, causing rapid leaf senescence.
Sudden shifts in temperature, particularly unexpected frost or extreme heatwaves, can trigger a stress response in 'Cold Play' lilies. This causes the plant to shed leaves to conserve moisture and energy for the bulb.
Small arachnids feed on the sap of Lily foliage, weakening the leaf structure. A heavy infestation can lead to rapid defoliation as the plant's ability to photosynthesize is severely compromised.
