Why does your Zantedeschia Captain Beretta have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Zantedeschia cultivars like 'Captain Beretta' are tropical plants that require high ambient moisture. Dry air, often caused by indoor heating, causes the delicate leaf margins to desiccate and turn brown.
Fluctuations between bone-dry soil and saturated conditions stress the rhizome. Additionally, the accumulation of mineral salts from tap water can burn the sensitive tips of Calla Lily foliage.
When the roots absorb water faster than the leaves can transpire it, cells in the leaf tips can burst. This cellular rupture leads to localized necrosis appearing as brown tips.
Excessive moisture at the base of the plant combined with poor airflow can trigger fungal pathogens. This often begins as small brown spots that eventually expand to the leaf tips.
