Rubber Plant Care: Light, Watering, Pruning and Leaf Drop
Rubber plant care indoors: the light Ficus elastica needs, how often to water, pruning to make it bushy, repotting, and why leaves drop or turn yellow.

Rubber plant care is straightforward: give Ficus elastica bright, indirect light with a little direct sun, water when the top 5 cm of soil is dry, keep it warm and away from drafts, and wipe the big leaves now and then. Prune in spring to make it bushy, and repot every couple of years. Most problems, especially falling leaves, come from low light, cold or uneven watering.
Rubber plants are fig trees from South and South-East Asia, where they grow into huge trees. Indoors they make tall, glossy plants with leaves in dark burgundy ('Burgundy', 'Black Prince'), green ('Robusta'), or variegated cream, pink and green ('Tineke', 'Ruby'). They're tougher and less sensitive than their cousin the fiddle leaf fig, which makes them a good first tree for a bright room.
Rubber plant care at a glance
| Need | What works | Avoid |
|---|---|---|
| Light | Bright indirect; a few hours of gentle sun | Dark corners; strong midday sun through glass |
| Water | When top 5 cm is dry; soak and drain | Wet soil for days; letting it dry out fully |
| Soil | Well-draining houseplant mix with bark and perlite | Heavy, dense compost |
| Temperature | 16–27°C | Below 12°C; drafts; radiators |
| Humidity | Average household is fine | Very dry air by heaters |
| Feeding | Monthly in spring and summer | Winter feeding |
| Repotting | Every 2–3 years, spring | Huge jumps in pot size |

Light
Rubber plants want bright light to stay full. Good spots include close to an east window, or a metre or two back from a south or west window. In medium light they're fine but grow slowly and shed lower leaves, leaving a bare stem. Variegated varieties lose their pink and cream colouring without enough light.
A few hours of direct morning sun is welcome. Strong afternoon sun through glass in summer can scorch the leaves, so filter it with a sheer curtain. Turn the pot every few weeks so the plant grows evenly. Check your spot with the plant light meter converter.
Watering
- Check the soil. When the top 5 cm is dry, water.
- Water evenly over the surface until it runs out of the drainage holes.
- Let it drain fully and empty the saucer or cover pot.
That usually lands at once every one to two weeks in summer and every two to four weeks in winter. The plant drinks more when it's bright and warm and much less in winter. Consistency matters: swinging between bone dry and soaking is a common trigger for leaf drop. The watering schedule tool gives you a starting interval to adjust.
| Signs | Too much | Too little |
|---|---|---|
| Leaves | Yellow, then drop, starting low | Droopy, curling, then crispy |
| Stem | Soft at the base (bad sign) | Firm |
| Soil | Wet for a week or more | Dry and light; pulling from the pot edge |
Soil and pots
Use a free-draining houseplant mix. A good recipe is two parts peat-free houseplant compost, one part orchid bark and one part perlite. Pots must have drainage holes. Rubber plants can get tall and top-heavy, so a heavier pot helps. Our houseplant soil mix guide covers alternatives.
Temperature and humidity
Normal room temperatures suit rubber plants. They dislike cold: below about 12°C, and in cold drafts from doors or windows, they may drop leaves. Average household humidity is fine, though very dry air near radiators can brown leaf edges.
Feeding
Feed monthly from spring to late summer with a balanced liquid fertiliser. Stop in autumn and winter. Use the fertilizer dilution calculator to get the dose right.
Pruning a rubber plant
Pruning keeps it a manageable size and encourages branching. Spring or early summer is the best time.
- Wear gloves; the milky latex is sticky and irritates skin.
- Decide where you want it to branch.
- Cut cleanly just above a leaf node (where a leaf joins the stem).
- Dab the cut with a damp paper towel until it stops bleeding sap.
- New shoots usually appear from one to three nodes below the cut within a few weeks.
For a fuller plant, cut different stems at different heights. You can also remove the top few leaves (called "notching" when you just nick above a node) to encourage a side shoot without cutting the whole top off.
Propagating rubber plants
- Stem cuttings: take a 15 to 20 cm tip cutting with a few leaves, let the sap stop, then root in water or moist perlite. A dusting of rooting hormone helps. Roots take four to eight weeks.
- Air layering: the best method for large, leggy plants. Roots form on the stem while it's still attached. See how to propagate houseplants.
Roll large leaves into a loose tube and tie them gently to reduce water loss while a cutting roots.
Repotting
Repot every two to three years in spring, going up just 5 cm in pot diameter. Slightly root-bound rubber plants grow fine, and staying in the same pot slows height growth if that's what you want. For very large plants, replace the top 5 cm of soil each spring instead. Use the repotting pot size calculator to pick a size and see how to repot a houseplant for the steps.
Common rubber plant problems
| Problem | Likely cause | Fix |
|---|---|---|
| Lower leaves dropping | Low light, cold, recent move | Brighter, warmer, steady spot |
| Yellow leaves | Overwatering; ageing lower leaves | Let soil dry more; check roots if many |
| Brown, crispy edges | Underwatering, dry heat | Water more evenly; move from radiator |
| Brown spots with yellow halo | Root rot from wet soil | See root rot treatment |
| Curling leaves | Thirst or cold | Check soil; move from drafts |
| Leggy, bare stem | Low light | More light; prune to encourage branching |
| Pale variegation | Not enough light | Move closer to window |
| Sticky leaves, bumps | Scale insects | Scrape and treat; see houseplant pests |
Leaf sheaths
New leaves grow wrapped in a red or pink sheath, which turns brown and falls off as the leaf opens. That's normal and not a problem.
Rubber plant in winter
Short days are the hardest time for a rubber plant. Move it a little closer to the window (but not touching cold glass), water less often, skip fertiliser and keep it away from radiators. Losing one or two lower leaves over winter is normal; losing many in a few weeks means it's too dark, too cold or too wet.
Rubber plant varieties
| Variety | Leaf colour | Light needs |
|---|---|---|
| 'Robusta' / 'Decora' | Glossy dark green | Medium to bright |
| 'Burgundy' / 'Black Prince' | Very dark red-black | Medium to bright |
| 'Tineke' | Green, cream and pale green | Bright |
| 'Ruby' | Pink, cream and green | Bright, for best pink |
| 'Shivereana' | Speckled yellow-green | Bright |

Frequently asked questions
How much light does a rubber plant need?
Bright, indirect light with some gentle direct sun is ideal, such as near an east window or a few feet back from a south or west window. Rubber plants tolerate medium light but grow slowly and lose lower leaves there. Variegated types need more light to keep their colour.
How often should I water a rubber plant?
When the top 5 cm of soil is dry, usually every one to two weeks in spring and summer and every two to four weeks in winter. Water thoroughly, let it drain and empty the saucer.
Why are my rubber plant leaves falling off?
Leaf drop is usually a reaction to change, such as moving to a new spot, cold drafts, low light or a swing between very dry and very wet soil. Overwatering that leads to root rot also causes lower leaves to yellow and drop. Keep conditions steady and check the roots if soil is staying wet.
How do I make my rubber plant bushier?
Cut the main stem in spring or early summer, just above a leaf node at the height you want. One or more side branches usually form below the cut within weeks. Pruning several stems at different heights gives a fuller shape.
Should I clean rubber plant leaves?
Yes. The large, glossy leaves collect dust that blocks light. Wipe both sides with a soft, damp cloth every few weeks. Avoid leaf-shine sprays, which can clog the leaf surface.
Is a rubber plant toxic to pets?
The ASPCA lists Ficus elastica as toxic to cats and dogs. The milky sap irritates skin and the mouth, so wear gloves when pruning and keep cut leaves away from pets.
