Red Zantedeschia aethiopica Brown Leaf Tips - Causes & Fixes

error

Low Humidity / Dry Air

Calla Lilies thrive in moist environments; dry indoor air, especially during winter heating, causes the leaf margins and tips to desiccate. This is common when the plant is kept in climate-controlled rooms without a humidifier.

Very Common

How to confirm: Check if the browning occurs primarily on newer leaves or during periods of low ambient humidity.

Salt Accumulation (Fertilizer Burn)

Excessive buildup of mineral salts from tap water or over-fertilization can cause osmotic stress, leading to scorched leaf tips. Red Calla Lilies are sensitive to high salt concentrations in their growing medium.

Very Common

How to confirm: Look for a white, crusty residue on the soil surface or the edges of the pot.

1 Flush the soil thoroughly with large amounts of distilled or rainwater to leach out accumulated mineral salts from the growing medium.

2 Repot the plant in fresh, high-quality potting soil to completely remove the salt-saturated medium and provide a clean environment.

Inconsistent Watering

Allowing the soil to dry out completely between waterings causes physiological stress that manifests as brown, crispy tips. While they dislike sitting in soggy soil, Calla Lilies require consistent moisture levels.

How to confirm: Insert your finger 2 inches into the soil to see if it has reached a bone-dry state before you last watered.

warning

Fungal Leaf Spot (e.g., Alternaria)

Pathogenic fungi can enter through wounded or stressed leaf tissue, causing necrotic brown spots that often start at the tips. This is more common in stagnant, humid conditions where airflow is restricted around the foliage.

Common

How to confirm: Examine if the brown areas are accompanied by dark, concentric rings or spreading lesions on the leaf blade.

1 Prune and remove all affected leaves to prevent the fungal spores from spreading to healthy foliage.

2 Apply a fungicide to treat the infection and improve air circulation around the plant to reduce humidity.
