Why does your Lily LA Hybrid Orange have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
This fungal pathogen thrives in the humid microclimates often found around dense LA Hybrid Lily foliage. It causes rapid tissue decay and can lead to sudden leaf abscission, especially during damp spring weather.
Soil-borne Fusarium can infect the bulb of LA Hybrids, obstructing the vascular system. As the fungus destroys the internal structure, the plant loses the ability to supply nutrients to foliage, causing sudden wilting and leaf drop.
LA Hybrids are sensitive to extreme temperature shifts; sudden heat waves or unexpected late frosts can trigger a stress response. This causes the plant to shed leaves as a survival mechanism to reduce transpiration.
Inconsistent moisture levels disrupt the heavy water demands of large-flowered LA Hybrids. Either extreme drought or saturated, anaerobic soil (leading to root suffocation) will cause the plant to shed leaves rapidly.
