Care at a glance
Light
Rubber plant is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Bright indirect light keeps leaves glossy and well-spaced. Variegated cultivars need brighter light; burgundy forms tolerate slightly less. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.
Watering
Water rubber plant when the top 3 cm of soil is dry, every 7-10 days. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Soak thoroughly then let excess drain. Yellow lower leaves are the first sign of overwatering.
Soil and pot
Rubber plant grows best in free-draining indoor tree mix. Standard potting compost with 20-30% perlite and a handful of orchid bark for structure. Repot every 2-3 years. 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
Rubber plant sits happiest at around 40-60% humidity and 18-26°C (65-80°F). Average humidity is fine. A pebble tray helps in winter. If you keep the room above 18 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 rubber plant sparingly. Balanced liquid feed at half strength every 4 weeks during the growing season. 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 rubber plant in the Growli community. Where a problem matches one of our diagnostic guides, click through for the full step-by-step recovery plan written for rubber plant specifically.
- Yellow leaves — Overwatering or sudden change in conditions.
- Brown patches on leaves — Sunburn or cold draught damage.
- Drooping leaves — Underwatering or root rot — check the soil first.
- Leaf drop after moving — Like fiddle-leaf figs, rubber plants sulk after relocation; give them 3-4 weeks.
Companion plants
Rubber plant pairs well with Fiddle leaf fig, Bird of paradise, and Monstera. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.
Propagation
Stem cuttings with one or two leaves root in water or moist mix in 4-6 weeks. Air-layering is more 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
Rubber plant is toxic to pets. ASPCA lists Ficus elastica as toxic to cats, dogs and horses due to the milky latex sap, which irritates skin and digestive tracts. 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.
Rubber plant care — frequently asked questions
What is the common name for Ficus elastica?
Ficus elastica is most commonly called Rubber plant, but it is also known as rubber tree, rubber bush, Indian rubber fig. The names refer to the same species, so care instructions for Rubber plant apply identically to anything sold as rubber tree.
How much light does rubber plant need?
Rubber plant grows best in bright indirect light (just back from a sunny window). Bright indirect light keeps leaves glossy and well-spaced. Variegated cultivars need brighter light; burgundy forms tolerate slightly less.
How often should I water rubber plant?
Water rubber plant when the top 3 cm of soil is dry, every 7-10 days. Soak thoroughly then let excess drain. Yellow lower leaves are the first sign of overwatering. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.
Is rubber plant toxic to cats and dogs?
Rubber plant is toxic to pets. ASPCA lists Ficus elastica as toxic to cats, dogs and horses due to the milky latex sap, which irritates skin and digestive tracts.
What USDA hardiness zone does rubber plant grow in?
Rubber plant is rated for USDA zone 10-12 (indoor-only) and RHS hardiness H1b. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
