Care Guide for Ficus elastica 'Robusta'
- Light: Prefers bright, indirect light. Tolerates lower light but grows slower. Avoid harsh direct sun.

- Soil: Use a well-draining mix with coconut coir and perlite or pine bark.
- Humidity: Normal room humidity is fine. In dry air, mist occasionally to prevent crisping edges.

- Feeding: Apply a balanced liquid fertilizer every 4–6 weeks year-round at half strength.
- Repotting: Every 2–3 years or when rootbound. Use breathable pots with drainage holes.
- Pruning: Cut back to control height or shape. Clean shears prevent sap spread and infections.
Common Problems and Solutions

- Brown tips: Low humidity or inconsistent watering. Raise humidity and maintain even moisture.
- Leaf drop: Caused by sudden light, draft, or watering changes. Keep conditions stable.
- Root rot: Results from soggy substrate. Repot in fresh mix and reduce watering frequency.

- Leaf care: Clean leaves regularly with a damp cloth or plant gloves to support healthy photosynthesis.
- Hydroponics: Can adapt to semi-hydro systems like LECA with stable nutrients and airflow.
