Why does your Lilium orientalis Mothers Choice 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 leaves, often preceded by small brown spots. In 'Mother's Choice', high moisture on the foliage can trigger a sudden collapse of the leaf structure.
Excessive soil moisture in heavy soils prevents oxygen from reaching the lily bulbs, leading to root decay. As roots die, the plant cannot support its large foliage, resulting in sudden leaf shedding.
Oriental lilies are sensitive to sudden heat waves; intense solar radiation can cause leaf tissues to desiccate and drop rapidly. This is common if 'Mother's Choice' is placed in a location receiving afternoon sun during mid-summer.
Severe infestations of spider mites can pierce individual leaf cells to feed on sap, causing rapid dehydration. This leads to a sudden yellowing and eventual drop of the foliage as the plant's vascular system is compromised.
