Why does your Lilium martagon have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Lilium martagon prefers moist but well-drained soil; excessive water around the bulb causes oxygen deprivation in the roots, leading to chlorosis (yellowing) of the foliage. This is often a precursor to fungal bulb rot.
Yellowing leaves, especially when starting from older, lower foliage, can indicate a lack of nitrogen or magnesium. This is common in lilies grown in depleted or highly leached soils.
This fungal pathogen causes leaves to turn yellow and eventually develop brown, water-soaked lesions. It thrives in high humidity and cool temperatures typical of the Martagon's native habitat.
While hardy, extreme heat spikes during the summer dormancy period can cause the foliage to yellow and wilt prematurely. This is a physiological response to prevent excessive transpiration.
