Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry conditions often experienced by Calla Lilies, spinning fine silk webs to create a protective microenvironment for their colonies. They feed on the plant's cells, causing the characteristic stippling or yellowing of the foliage.

Very Common

High Humidity/Microclimate Mold

While less common than mites, extremely high localized humidity around the base of the Calla Lily's fleshy stems can sometimes cause fungal hyphae to appear as fine, hair-like filaments.

Common

How to confirm: Check if the webbing feels dry and brittle like silk or if it appears fuzzy and organic like mold growth on decaying tissue.

1 Improve airflow around the base of the plant by spacing it away from other dense foliage and using a small fan if necessary.

2 Reduce localized humidity by ensuring the soil surface dries out between waterings and avoiding water accumulation in the plant's crown.
