Why does your Lily New Wave have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
This fungal pathogen thrives in high humidity and causes rapid leaf senescence and dropping. It often begins with small brown spots that quickly expand, leading to the premature death of the foliage.
New Wave Lilies are sensitive to sudden fluctuations in temperature. A sharp drop in temperature or a late spring frost can trigger the plant to shed leaves as a survival mechanism to protect the bulb.
Excessive moisture in the soil leads to Phytophthora or other root-rotting pathogens, which prevents the plant from supporting its foliage. As roots decay, the plant loses the ability to transport water, causing sudden leaf drop.
This-specific fungal infection attacks the leaf tissue, causing necrotic spots that eventually lead to the detachment of entire leaves. It is common in lilies during periods of wet weather.
