🌱 How to Care for Narrow-Leaf Fig to Prevent Anthracnose?

💧 How to Water

Water thoroughly when the top 2-5 cm (1-2 in) of soil feels dry, then let the pot drain fully - this ficus is more tolerant of brief dryness than of soggy, waterlogged soil, which quickly leads to root rot.

☀️ Lighting

Place in bright, indirect light close to a window; a few hours of gentle morning sun is fine, but shield the plant from intense direct midday sun, which can scorch the narrow leaves.

🪴 Ideal Soil

Use a well-draining, fertile potting mix (standard potting soil amended with perlite or coarse sand) with a near-neutral pH of about 6.0-7.5, and always choose a pot with drainage holes.
