Commonly known as: XL Rubber Tree Robusta
Botanical name: Ficus elastica ‘Robusta’
XL Rubber Tree Robusta delivers bold foliage and clean structure without variegation. The large, thick leaves emerge deep green with a glossy finish, creating a strong visual anchor in a room. Unlike variegated varieties, Robusta keeps a solid green tone, which makes it easy to pair with different interiors.
At 90cm–1m tall in a 30cm pot, these plants already have weight and presence. The upright growth habit keeps the silhouette neat, while the wide leaves add depth and fullness. Positioned correctly, it works well as a floor plant in living areas, offices, or entrance spaces.
Light plays an important role in maintaining strong leaf development. Bright, indirect light encourages firm growth and balanced spacing between leaves. Stable watering and proper drainage help prevent stress. With consistent care, Rubber Tree Robusta grows steadily upward and can be pruned to encourage branching if desired.
XL Rubber Tree Robusta Care Guide
Watering – How often should it be watered?
Water once the top 4–6cm of soil has dried out. Keep the soil evenly moist but never waterlogged. Always allow excess water to drain fully.
Light – What light does XL Rubber Tree Robusta need?
Bright, indirect light works best. A position near a large window with filtered light supports healthy growth. Avoid harsh afternoon sun, which can scorch leaves.
Humidity – Does it need extra humidity?
Average indoor humidity is sufficient. Keep it away from heaters and cold drafts to prevent leaf stress.
Soil – What soil works best?
Use a structured, well-draining mix. Indoor Potting Soil works well as a base. Improve airflow and drainage by incorporating Perlite and Bark Chips.
Feeding – How should it be fertilised?
Feed during spring and summer with Grobest Organic Fertiliser every 4–6 weeks. For stronger seasonal growth, Novatec Soluble Fertiliser can be used occasionally at reduced strength.
Repotting – When should it be repotted?
Repot every 18–24 months or once roots begin filling the pot. Move up one size only. When repotting, incorporate TerraPlus Natura N and Controlled Release Fertiliser into fresh mix.
Pests – What pests should I watch for?
Inspect leaves and stems for scale and spider mites. Treat early with an insecticidal spray if needed.
Temperature – What temperature suits it best?
Rubber Tree Robusta grows well between 18°C and 28°C. Avoid temperatures below 15°C and sudden environmental changes.
