Rubber plant (Ficus elastica) wants bright indirect light, moderate watering once the top of the soil has dried, and steady warmth away from cold drafts. It is a fast-growing, tree-like fig with large glossy leaves, it drops leaves when overwatered or chilled, and it is toxic to cats and dogs through its milky sap. It is not the same plant as jade plant, which is sometimes sold under a "rubber plant" nickname.
| Attribute | What a rubber plant needs |
|---|---|
| Light | Bright indirect light; minimum 75 to 100 foot-candles, prefers 200 to 500 |
| Water | Moderate; water once the top of the soil has dried, never leave the pot in standing water |
| Humidity | Likes some humidity; average household air is acceptable |
| Soil / pot | Well-draining potting mix in a pot with drainage holes |
| Fertiliser | Balanced fertiliser at half strength monthly in spring and summer; none in winter |
| Temperature | Keep at normal room warmth; cold drafts and sudden drops cause leaf loss |
| Toxicity | Toxic to cats and dogs, ASPCA direct entry (Indian rubber plant) |
Is a rubber plant the same as a jade plant?
No. The rubber plant or rubber tree is Ficus elastica, a tall, fast-growing fig, while jade plant (Crassula ovata) is an unrelated succulent. Per North Carolina State Extension, jade plant carries the nicknames Chinese rubber plant, dwarf rubber plant and Japanese rubber plant, so a tag reading only "rubber plant" can mean either. The two need opposite care: jade plant is a succulent that dries out fully between waterings, while Ficus elastica wants moderate water and some humidity. This site's own jade plant guide covers the succulent side of the mix-up. A third plant, the "American rubber plant" (Peperomia obtusifolia), is also unrelated and is covered by the peperomia guide.
| Sold as | Actual plant | Growth habit | Water |
|---|---|---|---|
| Rubber plant / rubber tree (this guide) | Ficus elastica | Tree-like fig, large glossy leaves | Moderate |
| Chinese, dwarf or Japanese rubber plant | Crassula ovata, see jade plant care | Slow succulent shrub, fleshy leaves | Dry out fully between waterings |
| American rubber plant | Peperomia obtusifolia, see peperomia care | Compact, semi-succulent leaves | Let the top soil dry between waterings |
How much light does a rubber plant need?
A rubber plant needs bright indirect light; North Carolina State Extension gives a minimum of 75 to 100 foot-candles and a preferred range of 200 to 500 foot-candles. Below the minimum the plant stretches and drops lower leaves, so a spot near a bright window suits it better than a dim corner. The general light guide explains how to read a room's light level.
How often should you water a rubber plant?
Water moderately, once the top layer of soil has dried, and never let the pot sit in standing water. North Carolina State Extension lists overwatering as a cause of leaf loss and describes the plant's water need as moderate, which sits between a succulent's and a calathea's. Soaking the pot, letting it drain fully and then waiting for the top of the soil to dry is the routine that avoids root rot. The watering guide covers the finger test, and overwatering vs underwatering shows how to tell the two faults apart.
Does a rubber plant need humidity?
A rubber plant likes some humidity, but average household air is acceptable. North Carolina State Extension notes it appreciates humid air without making it a strict requirement, so it is far less fussy than calathea. Dry air in winter is the main time to help it with a pebble tray or a nearby humidifier. The humidity guide lists which plants need more.
What soil and pot does a rubber plant need?
Use a well-draining potting mix in a pot with drainage holes. A fast-growing tree-like plant in a heavy, water-retaining mix is exactly the setup that leads to overwatering, so add perlite or bark to a standard mix for aeration. Repot into the next pot size up when roots circle the pot or push out of the drainage holes; an oversized pot stays wet too long. See the soil and pot guide and the repotting guide.
How and when do you fertilise a rubber plant?
Feed with a balanced fertiliser at half strength about monthly during spring and summer, and stop entirely in winter. Rubber plants are moderate feeders and growth slows sharply in low winter light, so winter feeding only builds up salts in the soil. The fertilising guide covers dilution and salt build-up.
What temperature does a rubber plant need?
Keep a rubber plant at normal room warmth and away from cold drafts; North Carolina State Extension names temperature drops and cold drafts as a cause of leaf loss. Keep it clear of window glass on winter nights, exterior doors and air-conditioning vents. Plant-care growers commonly put the floor at about 60 to 65°F (16 to 18°C). See the temperature guide for comparison across plants.
How do you prune a rubber plant?
Cut the stem back to just above a node, and the plant grows two or more new shoots from below the cut instead of one. A single-stem rubber plant that has grown tall and bare can be cut to a node bearing two or three leaves to encourage side branching. The cut oozes milky sap, so wear gloves, keep it off skin and eyes, and keep pets away from the trimmings.
How do you propagate a rubber plant?
Take a stem-tip cutting with at least one node and two or three leaves, or air layer a section of stem while it is still attached to the plant. Air layering, which wounds a section of stem and wraps it in moist medium until it roots, has the highest success rate and suits a tall plant that has gone bare at the base. Cuttings are simpler but slower to root. Both use the same rule as this site's propagation guide: keep the cutting warm and lightly moist and do not overwater it while it roots.
Why is my rubber plant dropping leaves or turning brown?
| Symptom | Likely cause | Fix |
|---|---|---|
| Several leaves dropping at once | Overwatering, a temperature drop or a cold draft | Check the soil is not wet, and move the plant away from drafts |
| One or two old bottom leaves yellowing | Normal ageing, per North Carolina State Extension | Remove the leaf; no action needed |
| Long, leaning growth, dropped lower leaves | Too little light | Move to a brighter spot |
| Soft, yellowing leaves, wet soil | Overwatering or root rot | Let the soil dry; check the roots |
| Webbing, sticky residue or small bumps on leaves | Spider mites, mealybugs or scale, the pests North Carolina State Extension lists | See the spider mites guide |
Is a rubber plant toxic to cats and dogs?
Yes. The ASPCA lists Indian rubber plant (Ficus elastica) as toxic to dogs and cats. The milky sap contains the proteolytic enzyme ficin and the skin irritant psoralen (ficusin), so chewing a leaf causes drooling, vomiting and oral irritation, and skin contact with sap can cause dermatitis. It belongs with fiddle leaf fig, another fig that shares the same ficin and psoralen sap, in the site's not-safe-for-pets table. If a pet has chewed one, call a vet or the ASPCA Animal Poison Control Center on (888) 426-4435.
FAQ
- Is a rubber plant the same as a jade plant?
- No. The rubber plant or rubber tree is Ficus elastica, a fast-growing, tree-like fig with large glossy leaves. Jade plant (Crassula ovata) is an unrelated succulent that some nurseries sell as a Chinese, dwarf or Japanese rubber plant, and it needs far less water. Check the botanical name on the tag.
- How often should you water a rubber plant?
- Water moderately, once the top layer of soil has dried out, and never leave the pot standing in water. Overwatering, not underwatering, is the usual cause of leaf loss, and North Carolina State Extension lists it first among the plant's problems.
- Why is my rubber plant dropping leaves?
- The usual causes are overwatering, a temperature drop or cold draft, and too little light. North Carolina State Extension notes that it is normal for a few bottom leaves to yellow and drop; several leaves at once points to a care fault.
- Is a rubber plant toxic to cats and dogs?
- Yes. The ASPCA lists Indian rubber plant (Ficus elastica) as toxic to dogs and cats. The milky sap contains the proteolytic enzyme ficin and the skin irritant psoralen (ficusin), causing drooling, vomiting, oral irritation and skin dermatitis.
- How do you propagate a rubber plant?
- Take a stem-tip cutting with at least one node and two or three leaves, or air layer a section of a tall, bare stem while it is still attached to the plant. Air layering roots more reliably; cuttings are simpler. Wear gloves, since the cut sap is an irritant.
