Rubber plant (Ficus elastica) care guide
Ficus elastica
Easy care⚠️ 🐾
Rubber plant (Ficus elastica) (Ficus elastica) does best when watered about every 7 days. Let the top 2–3 cm of soil dry out before watering again; adjust the rhythm to season and light.
Place it in bright indirect light. Humidity needs are average room. The comfortable temperature range is 18–25°C. During the growing season, feed it about every 30 days.
Care difficulty: easy — great for beginners.
⚠️ Pet safety: Rubber plant (Ficus elastica) is toxic to cats and dogs. Milky sap irritates skin and mucosa. Keep it out of reach, and if your pet chews it, contact a vet.
The rubber plant earned its name honestly: every cut or snapped leaf bleeds thick white latex, the same stuff once tapped for rubber. It is the most forgiving of the big indoor figs, with thick leathery leaves that tolerate dry air and the odd missed watering far better than a weeping fig or fiddle-leaf fig. Left alone it grows as a single tall stem that rarely branches by itself, so shaping it is up to you. Give it bright indirect light, 18–25°C and water about every 7 days when the top few centimetres are dry. Variegated types such as Tineke or Ruby need the brighter end of that light to keep their colour. The latex irritates skin and the mouths of pets.
Common problems and fixes
Lower leaves turning yellow and falling off
Why: Most often overwatering: rubber plant roots sit in a big pot of soil that stays wet for weeks. The loss of one old leaf now and then is normal ageing.
What to do: Let the top 3–5 cm dry before watering, empty the saucer and make sure the pot has holes. If several leaves go at once, check the roots for rot.
Rubber plant leaves drooping or curling
Why: Thirst, if the soil is dry right through, or a cold draft if it stands by a door or a window opened for airing.
What to do: Soak dry soil thoroughly and the leaves perk up within a day. If the soil is moist, move the plant out of the draft and keep it above 18°C.
White sticky liquid dripping from the stem
Why: It is latex, not a disease. It leaks from any wound: a pruning cut, a broken leaf, a scratch from a pet.
What to do: Blot it with a paper towel or hold a damp cloth to the cut until it seals, usually within minutes. Protect floors and wear gloves, as it stains and irritates skin.
Rubber plant growing tall with only one stem
Why: Ficus elastica has strong apical dominance: the top bud suppresses all the buds below it.
What to do: In spring cut the stem just above a leaf at the height you want branches. Two or three buds below the cut will sprout within a few weeks.
Variegated rubber plant losing its colour
Why: Too little light. The plant makes more green chlorophyll to compensate, so new leaves come out darker and the cream or pink fades.
What to do: Move it closer to a bright window with indirect light. New leaves will keep their pattern; leaves that already turned green won't change back.
Dry brown patches on rubber plant leaves
Why: Sunburn from hot midday sun through glass, or leaves pressed against a cold window in winter.
What to do: Keep it in bright indirect light, a little back from south-facing glass, and make sure leaves don't touch the window.
Care through the seasons
☀️ Spring and summer
From spring to late summer a healthy rubber plant produces a new leaf every couple of weeks, each unfurling from a red or pink sheath that dries and falls off by itself. Water about every 7 days when the topsoil is dry, feed every 30 days, and do pruning, air layering and repotting in spring so wounds heal fast. Wipe the big leaves with a damp cloth monthly; clean leaves catch more light.
❄️ Autumn and winter
From October to February growth slows and the plant uses much less water, so stretch the interval between waterings and skip fertilizer. Keep it at 18–25°C and away from radiators and cold glass. Rubber plants handle dry winter air well, so there is no need for misting; just keep the leaves free of dust.
How to propagate
Air layering is the classic method for rubber plants and the best way to shorten a plant that has hit the ceiling. Make an upward cut a third into the stem below a leaf, wedge it open with a matchstick, wrap it in damp sphagnum moss and cling film, and cut off the rooted top after 6–8 weeks.
Tip cuttings 15–20 cm long root well too. Rinse the latex off the cut under running water, let it dry for an hour, remove the lower leaves and roll the top leaf loosely with a rubber band to reduce water loss. Root in water or moist perlite at 22–25°C; roots take about 4–6 weeks.
The old stump you cut from will not die: it will branch from the buds just below the cut, so propagation doubles as pruning.
Tips from experience
- The red sheath around a new leaf is supposed to dry up and drop; don't peel it off early.
- Prune in spring and have paper towels ready for the latex.
- Wipe the leaves instead of using leaf-shine sprays, which clog the pores.
- Variegated varieties need more light than plain green ones.
- Plantik can remind you to check the soil about every 7 days so the big pot never stays soggy.

▸How often should I water Rubber plant (Ficus elastica)?
About every 7 days. In winter or lower light, stretch the interval; in hot bright rooms, shorten it slightly. Always check the soil first.
▸What light does Rubber plant (Ficus elastica) need?
Rubber plant (Ficus elastica) prefers bright indirect light, with a comfortable range of 18–25°C.
▸Is Rubber plant (Ficus elastica) toxic to cats and dogs?
Yes. Milky sap irritates skin and mucosa.
▸How often should I fertilize Rubber plant (Ficus elastica)?
Roughly every 30 days during spring and summer; pause or halve feeding in winter.
▸How do I make my rubber plant bushier?
Cut the main stem in spring just above a leaf node. New branches will grow from the buds below the cut, and you can root the top as a new plant.
▸Is rubber plant latex dangerous?
It irritates skin, eyes and the mouth, and it is a problem for people with latex allergy. Wear gloves when pruning and keep pets from chewing leaves.
▸How often should I water a rubber plant?
About every 7 days in spring and summer, once the top 3–5 cm of soil are dry. In winter water less often.
▸Why does my rubber plant have a red sheath on top?
That is the protective sheath of the next leaf. It is normal and drops off once the leaf unfurls.
