Glossy and upright, the rubber plant wants bright filtered light and a thorough but unhurried watering routine — moderate in summer, sparing in winter, always letting the top of the compost dry first. It hates cold draughts and sudden moves, dropping leaves when it sulks, and its milky sap is an irritant. Ficus elastica is toxic to cats and dogs.

Care at a glance

Light
Bright, filtered or indirect lightAn east window or just back from a brighter one; variegated forms need more light to hold their cream and pink. Shield from harsh afternoon sun.
Water
Moderately in growth, sparingly in winterLet the top few centimetres dry, then water thoroughly and drain. Both extremes drop leaves, so aim for even, unhurried watering.
Soil
Free-draining houseplant compostA loam-based or multipurpose mix with added perlite or bark to keep it open.
Humidity
Average humidity is fineTolerates dry rooms; wiping the big leaves keeps them glossy and dust-free.
Temperature
16–24 °C (61–75 °F)Keep above 13 °C (55 °F) and well away from cold draughts and heat sources, both of which trigger leaf drop.
Difficulty
EasyStraightforward once settled, but it resents being moved and shows it by shedding leaves.
Pets
Toxic to petsToxic to cats and dogs — the milky latex sap irritates the mouth, gut and skin (ASPCA, as Indian Rubber Plant).

Propagation

Take a tip or stem cutting in late spring with two or three leaves. The cut weeps sticky white latex, so dab it with a tissue and let the end dry briefly; the sap can irritate skin, so wash your hands afterwards.

Root the cutting in water or in damp, gritty compost kept warm and lightly shaded — rooting takes several weeks and is more reliable with bottom heat. To rejuvenate a tall, bare specimen, air-layering is the surer method: wound the stem, wrap the spot in damp moss and plastic until roots form, then sever below the new roots.

Common problems

  • Sudden leaf drop

    Likely cause: A change in conditions — a draught, a cold spell, a move to a new spot, or over/under-watering. Ficus dislikes change.

    Fix: Settle it in one stable, bright, draught-free position and keep watering even; new leaves return once it adjusts.

  • Lower leaves yellowing then falling

    Likely cause: Usually overwatering and cold, wet roots, though a little natural loss of old leaves is normal.

    Fix: Let the compost dry further between waterings, check drainage, and keep it warmer.

  • Brown, scorched patches on the leaves

    Likely cause: Direct, hot sunlight burning the broad leaf surface.

    Fix: Move it to bright but filtered light, away from glass that magnifies midday sun.

Frequently asked questions

Why is my rubber plant dropping leaves?

Leaf drop is the rubber plant's stress signal, almost always triggered by change: a cold draught, a sudden move, or swings between bone-dry and waterlogged soil. Pick a settled position with steady warmth and light, keep the watering even, and the shedding stops as it adjusts.

How do I make my rubber plant branch instead of growing straight up?

Cut off the growing tip just above a leaf. Removing the top bud forces dormant buds lower down to break, giving you two or more side branches. Spring is the best time, and you can root the cut-off top as a new plant.

Is the white sap from a rubber plant dangerous?

The milky latex is an irritant rather than a serious poison: it can sting skin and eyes and upset the stomach if eaten, and people with latex allergies may react. Wash your hands after pruning and keep it away from pets and children.

Why are my variegated rubber plant's new leaves turning plain green?

Variegated forms such as 'Tineke' need plenty of bright light to keep their cream and pink markings. In dim conditions the plant reverts to more efficient all-green leaves; move it brighter and prune back the plain growth.
