Ficus elastica ‘Robusta’ – Care Guide

Light

Thrives in bright, indirect light but tolerates moderate light conditions. It prefers filtered sunlight, though it can adapt to slightly lower light. Avoid prolonged direct sunlight, which may scorch the leaves, and avoid very dim areas where growth may slow.

Watering

Water when the top 3–5 cm of soil feels dry to the touch. Keep the soil lightly moist in spring and summer but allow it to dry slightly between waterings. In winter, water less frequently. Always ensure good drainage, as Ficus ‘Robusta’ dislikes sitting in waterlogged soil.

Temperature and Humidity

Temperature: Prefers warmth between 18–28 °C. Protect from cold drafts and sudden temperature changes.
Humidity: Average indoor humidity (40–60%) is usually sufficient. Mist occasionally or wipe the leaves with a damp cloth to remove dust and maintain their healthy shine.

Soil and Potting

Use a rich, well-draining potting mix — compost combined with perlite and a little bark or sand is ideal. Repot every 2–3 years in spring to refresh nutrients and allow room for root growth. Choose a heavy, stable pot to support its upright form.

Feeding

Feed every 4–6 weeks during the growing season (spring and summer) with a diluted, balanced liquid fertiliser. Avoid over-fertilising and suspend feeding in autumn and winter.

Pruning and Maintenance

Prune lightly in spring or summer to shape the plant and control height. Remove any yellowing or damaged leaves at the base. Wipe the large leaves regularly with a soft, damp cloth to restore their shine and support photosynthesis. Rotate occasionally to encourage even growth.

Growth and Maturity

A moderate to fast grower, Ficus ‘Robusta’ can reach 2–3 metres indoors with time and care. It forms a strong, upright trunk and broad, glossy leaves that create an effortlessly tropical statement. With consistent care, this variety can live for decades, becoming more impressive each year.

Common Issues

• Yellowing leaves: Overwatering or poor drainage.

• Brown edges: Low humidity or under-watering.

• Leaf drop: Caused by environmental change, drafts, or inconsistent watering.

• Pests: Occasionally affected by scale or spider mites — treat with neem oil or insecticidal soap.

Background and Benefits

Ficus elastica ‘Robusta’ is a cultivar of the traditional Rubber Tree, once grown extensively for its latex-producing sap. Today, it’s primarily cultivated as an ornamental plant, admired for its durability and glossy aesthetic. Its large leaves help purify the air by filtering toxins such as formaldehyde and benzene, making it both beautiful and beneficial.

A long-time interior design favourite, ‘Robusta’ symbolises endurance, stability, and abundance — qualities that make it as meaningful as it is striking.
