Ficus elastica is an easy plant to grow if watering is managed carefully. Allow the compost to dry to the touch before watering again, and never let the pot sit in water. While it tolerates average household humidity, you can mist the leaves in summer to boost moisture, and occasionally clean them with a damp sponge or cloth to keep the foliage glossy.
Feed monthly during spring and summer with a balanced houseplant fertiliser. Place in bright, indirect light for best growth, though it will adapt to slightly lower light. Keep temperatures stable, avoiding draughts or sudden fluctuations, and ensure the plant does not drop below a minimum of 12°C (54°F) in winter. Repot every 2-3 years in spring, or refresh and topdress the compost on larger plants, pruning if needed to maintain a neat, bushy habit.
