Why does your Zantedeschia Cantor have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Calla Lilies thrive in moist environments; dry indoor air causes the leaf margins to desiccate and turn brown. This is particularly common in heated homes during winter months.
Excessive buildup of fertilizers or minerals from tap water can burn the sensitive leaf tips of Zantedeschia. This often manifests as localized browning at the very edge of the foliage.
Allowing the soil to dry out completely between waterings causes physiological stress, leading to tip necrosis. Calla Lilies prefer consistently moist, but not waterlogged, substrate.
While less common for just tips, certain fungal pathogens can cause necrotic lesions that expand toward the leaf margins in humid conditions. This is usually accompanied by darker, water-soaked patches.
