🌱 How to Care for Chinese Banyan to Prevent Bacterial Leaf Spot?

💧 How to Water

Water every 7 days, allowing the top 2–3 cm of soil to dry out between waterings. Reduce frequency in winter. Never let roots sit in water — good drainage is essential to prevent root rot.

☀️ Lighting

Needs bright indirect light — ideally placed near a south or west-facing window. Can tolerate a few hours of morning sun. Avoid sudden changes in light position, as the plant is sensitive to environmental shifts and may drop leaves.
