Burgundy Rubber Plant (black rubber plant) care

Light

Bright but filtered. Burgundy Rubber Plant burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright, indirect light keeps the leaves their darkest burgundy; too little light and new growth reverts to plain green and stretches. A few hours of gentle morning sun is fine, but harsh midday sun scorches the foliage. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering burgundy rubber plant: when the top 3-5 cm of soil is dry, roughly every 7-10 days in growth. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Water thoroughly until it drains, then let the top few centimetres dry before watering again. Overwatering causes yellowing and lower-leaf drop; let it dry more in winter. Wipe the broad leaves to keep them glossy and dust-free.

Soil and pot

Burgundy Rubber Plant grows best in well-draining, peat-free houseplant mix. A free-draining mix of coir or potting compost with added perlite and bark or orchid mix. Must drain freely — soggy roots cause rot. Slightly acidic to neutral pH suits it best. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Burgundy Rubber Plant sits happiest at around 40-60% humidity and 16-29°C (60-84°F). Tolerates average household humidity well but appreciates moderate moisture; very dry air can brown leaf edges. Keep away from radiators and cold drafts, both of which stress the plant and trigger leaf loss. If you keep the room above 16 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed burgundy rubber plant sparingly. Feed every 2-4 weeks through spring and summer with a balanced liquid houseplant fertiliser at half strength; pause in autumn and winter when growth slows. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on burgundy rubber plant in the Growli community. Each is annotated with the most common cause so you know where to start.

• Leaf drop after a move — Ficus elastica hates change — relocation, drafts or sudden temperature swings cause sudden leaf shedding. Settle it in one stable spot away from doors and vents.
• Yellowing lower leaves — Usually overwatering or poor drainage. Let the top few centimetres dry between waterings and ensure the pot drains freely.
• Reverting green growth — Insufficient light fades the deep burgundy and produces plain green, leggy growth. Move to a brighter indirect spot to restore colour.
• Sap latex sensitivity — The white latex irritates skin and is toxic to pets. Wear gloves when pruning and wipe away drips to avoid staining surfaces.

Propagation

Propagate by stem-tip cuttings or air-layering in spring and summer. Take a cutting with 1-2 leaves, rinse the milky sap, let it callus briefly, then root in moist mix or water; air-layering is the most reliable for thick stems. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Burgundy Rubber Plant is toxic to pets. Toxic to cats and dogs. The ASPCA lists Ficus (Indian rubber plant) as toxic, with toxic principles ficin (a proteolytic enzyme) and ficusin (psoralen) concentrated in the milky white sap. Ingestion or sap contact can cause oral and skin irritation, drooling, vomiting, diarrhoea and decreased appetite. Keep out of reach of pets and wash hands after pruning. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
