Why does your Ficus aurea have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Ficus aurea is a tropical species that thrives in high humidity; dry indoor air causes the leaf margins to desiccate and turn brown. This is especially common during winter months when indoor heating reduces ambient moisture.
Excessive buildup of mineral salts from fertilizers in the potting medium can draw moisture out of the leaf tips. As the plant transpires, these salts concentrate at the furthest extremities of the foliage.
Allowing the root ball of a Ficus aurea to dry out completely before watering causes physiological stress. Fluctuations between extreme drought and saturation disrupt the plant's hydraulic pressure, leading to necrotic tips.
Ficus species can be sensitive to the chlorine and fluoride levels found in municipal tap water. These chemicals accumulate in the leaf tissue over time, eventually causing tip necrosis.
