Why does your Kalanchoe Rosalina Don Geraldo have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Kalanchoes are sensitive to accumulated salts from tap water or excessive synthetic fertilizers. When salts build up in the leaf tissue, they draw moisture out of the cells, causing the tips to desiccate and turn brown.
As succulents, Kalanchoes can handle dry air, but extreme drops in humidity (often caused by indoor heating) can cause rapid transpiration from the leaf edges. This leads to localized tissue death at the furthest points from the moisture source.
While Kalanchoe 'Don Geraldo' is drought-tolerant, prolonged periods where the soil stays bone-dry can cause the plant to sacrifice its leaf tips to conserve moisture. This results in crispy, brown margins.
Sudden exposure to intense, direct afternoon sunlight can overwhelm the photosynthetic capacity of the leaf edges. This thermal stress causes the delicate tissue at the tips to burn and turn brown.
