Why does your Lilium OT Theo 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 senescence of leaves. The fungus attacks the leaf tissue, often starting with brown spots that lead to sudden defoliation.
Excessive moisture at the bulb level causes the roots to decay, cutting off the supply of nutrients and water to the foliage. This sudden interruption in transpiration often triggers a stress response resulting in rapid leaf drop.
Lilium OT hybrids are sensitive to extreme temperature fluctuations. A sudden heatwave or an unexpected late frost can cause the plant to enter a forced dormancy state, shedding leaves to protect the bulb.
A sudden depletion of mobile nutrients in the soil can lead to rapid chlorosis and leaf abscission. If the lily has just finished a heavy blooming period, it may have exhausted available soil resources.
