Rubber Plant Care: Light, Water, Pruning and Leaf Drop Fixes

A rubber plant (Ficus elastica) gives you big, glossy, almost leather-like leaves and grows into a striking indoor tree. It is easy to keep once you get two things right: bright light and careful watering. Most problems, from dropping leaves to droopy stems, trace back to one of those.

Rubber plant care at a glance

Need	What a rubber plant wants
Light	Bright, indirect light; 1 to 2 hours of gentle morning sun is fine
Water	When the top 1 to 2 inches are dry; less in winter
Soil	Well-draining indoor potting mix with extra perlite or bark
Temperature	60 to 80°F (16 to 27°C); keep above 55°F (13°C)
Humidity	Average home humidity (40 to 50%) is fine
Fertilizer	Balanced liquid feed at half strength, monthly in spring and summer
Growth	Fast in good light; 6 to 10 feet indoors if not pruned
Pets	Keep away: the milky sap can irritate mouths and skin

How much light does a rubber plant need?

Rubber plants grow best in bright, indirect light. A spot a few feet from an east-facing window is ideal, or set back from a south or west window behind a sheer curtain. A little soft morning sun keeps the leaves glossy and the color deep, especially on burgundy and variegated types.

• Too little light: long gaps between leaves, small new leaves, a plant leaning toward the window, and lower leaves dropping.
• Too much harsh sun: bleached, pale or brown crispy patches on the leaves facing the window.
• Variegated types (‘Tineke’, ‘Ruby’) need the brightest spot. In low light their cream and pink patches fade back to green.

Turn the pot a quarter turn every couple of weeks so the trunk grows straight. Our houseplant light guide shows how to judge your windows.

How often to water a rubber plant

Water when the top 1 to 2 inches of soil feel dry. In a bright room in spring and summer that is usually every 1 to 2 weeks. In winter, when growth slows, it can be every 2 to 4 weeks.

1. Push a finger 2 inches into the soil. If it is dry, it is time.
2. Water slowly until water runs out of the drainage hole.
3. Let it drain for 15 to 30 minutes, then empty the saucer.
4. Do not water again until the top layer dries out.

A rubber plant is a little more forgiving of thirst than of wet feet. If you are unsure, wait a few more days. More tips in our watering guide.

Best soil and pot

Use a well-draining indoor potting mix. Mixing in about one part perlite or orchid bark to three parts potting mix gives the roots air and stops the soil staying soggy. Always use a pot with a drainage hole.

Rubber plants grow well when slightly snug in their pot. Choose a pot only 1 to 2 inches wider than the root ball. Heavy ceramic or terracotta pots help stop tall plants from tipping. Our potting soil guide has simple recipes.

Temperature and humidity

Keep a rubber plant between 60 and 80°F (16 to 27°C). It dislikes cold more than heat: below about 55°F (13°C) leaves can drop, and a cold draft from a door or window in winter often causes sudden leaf loss.

• Keep it away from radiators, heating vents and air conditioners.
• Average room humidity is fine. Dusty leaves block light, so wipe them with a damp cloth every few weeks.
• Do not use leaf-shine products. They clog leaf pores.

See our temperature guide and humidity guide for more.

Fertilizing a rubber plant

Feed with a balanced liquid houseplant fertilizer at half strength once a month from spring to late summer. Stop in autumn and winter. Always fertilize damp soil, never bone-dry soil, and skip feeding for 4 to 6 weeks after repotting. Our fertilizing guide explains the details.

How to prune a rubber plant to make it bushy

Left alone, a rubber plant grows as a single tall stem. Pruning the top makes it branch out and grow fuller.

1. Prune in spring or early summer, when the plant is growing fast.
2. Wear gloves. Cut stems leak a milky white sap that can irritate skin and stain floors, so put a cloth down.
3. Use clean, sharp pruners. Cut about 1/4 inch above a leaf node (where a leaf meets the stem) at the height you want.
4. Dab the cut with a damp paper towel until the sap stops.
5. Expect 1 to 3 new branches to grow from just below the cut within a few weeks.

Never remove more than a third of the plant at once. Our pruning guide shows exactly where to cut.

How to propagate a rubber plant

The tip you prune off can become a new plant.

1. Take a 6 to 8 inch tip cutting with 2 to 3 leaves. Remove the lowest leaf.
2. Let the sap stop, then rinse the cut end.
3. Place the cutting in water or a small pot of moist potting mix with perlite.
4. Keep it warm and in bright, indirect light. A clear bag over the top raises humidity.
5. Roots usually form in 3 to 6 weeks. Pot water-rooted cuttings when the roots are 1 to 2 inches long.

You can roll large leaves gently and tie them loosely to save space and reduce water loss. More methods in our propagation guide.

When and how to repot

Repot every 1 to 2 years in spring, or when roots poke out of the drainage holes and water runs straight through. Move up only one pot size. If the plant is already as tall as you want, refresh the top 2 inches of soil instead of repotting. See our repotting guide.

Common rubber plant problems and fixes

What you see	Most likely cause	What to do
Lower leaves turn yellow and drop, soil wet	Overwatering	Let soil dry, check roots, water less often
Sudden leaf drop after a move or cold night	Shock or cold draft	Keep it in one warm, bright spot; it will regrow
Drooping leaves, dry soil	Underwatering	Water thoroughly; it should perk up in a day
Leggy stem, small leaves, big gaps	Too little light	Move closer to a bright window; prune to branch
Brown crispy patches on sunny side	Sunburn	Move out of harsh afternoon sun
Brown edges or tips	Uneven watering or salt build-up	Water deeply, flush the soil every few months
Sticky leaves, white fluff or tiny bumps	Mealybugs or scale	Wipe with rubbing alcohol, repeat weekly
Fine webbing, speckled leaves	Spider mites	Rinse leaves, use insecticidal soap

Is a rubber plant toxic to pets?

Treat a rubber plant as mildly toxic. Its milky latex sap can irritate skin and, if a cat or dog chews a leaf, may cause mouth irritation, drooling or vomiting. Place it out of reach of curious pets and wear gloves when pruning. If you need pet-safe alternatives, see our pet-friendly houseplants.
