Why does your Kalanchoe Passion Nilus have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Kalanchoe species are sensitive to high concentrations of salts from tap water or excessive fertilizers. These salts accumulate at the leaf margins, causing the tips to desiccate and turn brown.
As a succulent, while it handles dry air better than tropicals, extreme drops in humidity combined with warm indoor heating can cause rapid transpiration at the leaf edges, leading to browning.
Allowing the soil to dry out completely and then saturating it causes osmotic stress. This fluctuation disrupts the hydraulic pressure in the succulent leaves, often manifesting as necrotic tips.
Excessive application of high-nitrogen fertilizers can lead to an accumulation of nutrients that pulls moisture out of the leaf cells through osmosis, burning the delicate tips of the Passion Nilus.
