Why does your Kalanchoe Passion Castalia have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Kalanchoe species are sensitive to salt buildup from tap water or excessive fertilizer. As the plant transpires, salts accumulate in the leaf margins, causing tissue desiccation and browning at the tips.
Passion Kalanchoe prefers moderate humidity; extremely dry indoor air can cause the delicate leaf margins to lose moisture faster than the roots can replace it, leading to crispy brown tips.
While Kalanchoes are succulents, allowing the soil to stay bone-dry for too long causes the plant to sacrifice its furthest extremities (the tips) to preserve moisture in the fleshy leaves.
Excessive moisture can damage the fine feeder roots of 'Passion Castalia'. When these roots die from lack of oxygen, they cannot transport water to the leaf tips, resulting in localized browning.
