Why does your Cycas revoluta have brown leaf tips? Diagnose the cause and fix it with our step-by-step guide.
Sago Palms are sensitive to dry air and inconsistent moisture. When the substrate dries out too completely, the tips of the stiff leaflets lose turgidity and undergo necrosis.
Accumulation of mineral salts from tap water or over-fertilization can cause osmotic stress. This prevents the distal ends of the leaflets from receiving adequate hydration, leading to chemical burn at the tips.
While underwatering is common, inconsistent watering cycles can lead to root damage. If roots cannot function due to fluctuations between saturation and drought, the tips will brown first.
Sudden exposure to cold drafts or extreme heat can shock the Cycad's vascular system. This thermal stress often manifests as localized tissue death at the leaf extremities.
