Why does your Camellia japonica have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Camellias are sensitive to high salt concentrations in the soil. Excessive use of synthetic fertilizers can lead to salt buildup, which draws moisture out of the leaf tips through osmosis, causing them to turn brown and crispy.
Japanese Camellias require consistent moisture and do not tolerate drying out completely. When the substrate dries too much, the plant cannot transport water to the furthest extremities of the leaf, resulting in necrotic tips.
As an understory plant, Camellia japonica thrives in humid environments. In indoor settings or very dry climates, low ambient humidity causes rapid transpiration from the leaf margins faster than the roots can replace it.
Camellias can be sensitive to the mineral content and chemicals in municipal tap water. High levels of fluoride or chlorine can cause tip burn as the plant accumulates these elements in the leaf margins.
