Powdery Mildew

A fungal disease caused by pathogens like Podosphaera aphanis, which thrives in high humidity and stagnant air around the large foliage of Calla Lilies. It manifests as white, flour-like patches on the leaves that can eventually lead to leaf necrosis.

Very Common

How to confirm: Check if the white spots appear as fuzzy patches on the upper surface of the leaves rather than a thin dust.

Mealybugs

Small, soft-bodied insects that secrete a white, waxy, cottony substance to protect themselves. They tend to hide in the crevices between the leaf sheath and the stem of the Zantedeschia.

Common

Calcium Deficiency (Lime Scale/Mineral Deposits)

Hard water deposits or excess minerals from fertilizers can leave white, crusty residues on the surface of the foliage. This is not biological but appears as a dry, white film often following water splashes.

Common
lightbulb
How to confirm: Wipe the residue with a damp cloth; if it disappears and doesn't feel fuzzy, it is mineral buildup.
build How to fix it
1 Gently wipe the foliage with a soft, damp cloth to remove the mineral deposits and prevent further buildup.
2 Switch to using distilled water or rainwater for irrigation to prevent new lime scale and mineral crust from forming on the leaves.
3 Flush the soil with pure water to leach out excess mineral salts and prevent them from accumulating on the plant surface.
