Why does your Kalanchoe Passion Poseidon have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Kalanchoe species are sensitive to dry air; when humidity levels drop, the transpiration rate exceeds moisture uptake, causing the delicate leaf margins to desiccate and turn brown.
Accumulation of fertilizer salts or hard water minerals (calcium/magnesium) in the substrate can cause osmotic stress, leading to necrotic brown tips.
If the substrate dries out completely for too long, the plant sacrifices its extremities to preserve moisture in the core, resulting in crispy brown tips.
Excessive nitrogen or concentrated liquid fertilizers can cause a high salt index in the soil, physically burning the leaf tissues starting at the tips.
