Why does your Lilium OT Big Brother 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 the foliage. As the fungus attacks the leaf tissue, the plant may shed leaves prematurely to mitigate further spread.
Lilium OT hybrids require well-draining soil; excessive moisture leads to anaerobic conditions in the bulb area. This disrupts the vascular system, causing the plant to shed leaves as it struggles to transport oxygen and nutrients.
Oriental-type hybrids like 'Big Brother' are sensitive to sudden temperature shifts or extreme heat waves. Rapid changes can trigger a stress response, leading to the shedding of older leaves to conserve energy.
A lack of available nitrogen prevents the plant from maintaining chlorophyll levels in its foliage. In lilies, this often manifests as yellowing lower leaves that eventually drop off.
