Overwatering and Root Rot

Calla Lilies are sensitive to stagnant water; excessive moisture causes Rhizome rot, which disrupts the plant's ability to transport water to the foliage, resulting in sudden drooping.

Very Common

How to confirm: Gently lift the rhizome from the soil to check if it is soft, mushy, or emitting a foul odor.

1 Immediately remove the plant from its current container and inspect the rhizome for mushy, dark, or foul-smelling rot.

2 Trim away all decayed roots and repot the plant in a well-draining, fresh medium like Espoma Organic Potting Soil Mix to prevent further rot.

Underwatering and Drought Stress

While they enjoy moisture, Zantedeschia aethiopica requires consistent hydration; when the growing medium dries out completely, the turgor pressure in the leaves drops, causing wilting.

Very Common

Temperature Fluctuations or Cold Stress

Purple Calla Lilies are tropical perennials that are highly sensitive to frost and cold drafts, which can cause metabolic slowdown and leaf collapse.

Common

1 Move your Calla Lily to a stable, warm environment away from cold drafts, windows, or air conditioning vents to prevent further metabolic shock.

2 Monitor the soil moisture closely using a moisture meter to ensure the plant isn't being overwatered while in its stressed, dormant-like state.

Nutrient Deficiency (Nitrogen)

A lack of essential nitrogen prevents the development of strong cell walls and chlorophyll, leading to weakened stems that cannot support the weight of the leaves.

Common

How to confirm: Look for a pale, yellowish tint on the older leaves in addition to the drooping symptom.
