Why does your Zantedeschia Captain Ventura have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
As tropical plants, Calla Lilies thrive in humid environments; dry indoor air causes the leaf margins and tips to desiccate and turn brown.
Excessive buildup of mineral salts from fertilizers can draw moisture out of the leaf tissues, leading to necrotic brown tips on the 'Captain Ventura' foliage.
Allowing the rhizome to dry out completely between waterings stresses the plant, causing the tips of the large leaves to crisp up.
High levels of chlorine, fluoride, or salts found in municipal tap water can cause tip burn in sensitive cultivars like 'Captain Ventura'.
