Rubber Plant (Ficus Elastica): Complete Care Guide

The rubber plant (Ficus elastica) is one of the most rewarding houseplants you can grow. Its large, thick, glossy leaves add a sculptural touch and it shrugs off neglect. With simple care it can go from a small pot to a near six-foot specimen.

Origin and character

It comes from Southeast Asia, where it grows into a huge tree. Indoors it stays far more compact but keeps that sturdy habit and those leathery leaves, which can be deep green, burgundy (the Abidjan variety) or variegated (Tineke, Ruby).

Light

• Ideal: bright, indirect light near a window with a sheer curtain.
• Variegated types: need more light to keep their pink and cream; in low light they revert to green.
• Avoid: harsh direct sun, which scorches the leaves, and very dark corners, where it stretches and drops lower leaves.

Watering

Water when the top 1-1.5 inches of soil are dry. In spring and summer that's usually every 7-10 days; in winter, much less. The rubber plant prefers to stay slightly dry rather than soggy.

Rule of thumb: if in doubt, wait one more day. Overwatering is its main enemy.

The classic overwatering sign is yellow leaves dropping from the bottom. If that happens, check our yellow leaves guide to rule out root rot.

Humidity and temperature

It tolerates average household humidity, though it appreciates a little extra moisture in the air. Keep it between 60 and 80 °F and away from cold drafts and radiators, which dry the leaves out.

The key: clean, glossy leaves

Its big leaves gather dust easily, and dust blocks the light the plant needs.

• Wipe the leaves every 2-3 weeks with a damp cloth, supporting each leaf from below with your other hand.
• Skip commercial leaf shines — they clog the pores. A cloth and water is all you need.

Soil and repotting

Use a good all-purpose mix with a handful of perlite for drainage. Repot every 1-2 years, in spring, into a pot a couple of inches larger and always with drainage holes.

Pruning to branch out

Left alone it grows as a single straight stem. For a bushier plant:

1. Cut the main growing tip with clean scissors, just above a node.
2. A white latex will ooze out — wipe it carefully (it irritates sensitive skin).
3. Within a few weeks, two or more new branches sprout below the cut.

Spring is the best time to prune and to root the cutting in water or soil.

Common problems

• Yellow leaves dropping: almost always overwatering.
• Lower leaves dropping on their own: normal with age, or low light if it's widespread.
• Brown, crispy edges: very dry air or hard, calcium-rich water.
• Leaf drop after moving it: it hates sudden changes; give it time to settle.

Is it toxic?

Yes. The milky sap contains compounds that irritate the skin and mouths of pets and children if chewed. Keep it out of reach and wear gloves when pruning.

With good light, careful watering and clean leaves, the rubber plant is one of those plants that grows year after year asking for almost nothing in return.
