Ficus Elastica (Rubber Plant): Care, Varieties & Growing Tips

The Rubber Tree Plant

Ficus elastica, the Rubber Plant, is a bold, fast-growing houseplant that can reach impressive heights in a few years. Its name comes from the milky latex sap that oozes from cuts – an irritant to skin and eyes, and toxic if ingested. On the plus side, it’s a top air purifier, pest-resistant, and boosts room humidity.

Modern cultivars have largely replaced the original species. Look for ‘Robusta’ (hardier), compact ‘Decora’, near-black ‘Black Prince’, and variegated types like ‘Doescheri’ (pink/purple flushes) or the common cream-and-green variegated form.

Rubber Plant Care Instructions

Light

Bright indirect light with some morning/evening sun. All-green types tolerate shade but become leggy; variegated forms need good light to keep markings.

Watering

Water thoroughly when the top half of soil dries out – typically once a week in summer. Never let it sit in water. In winter, keep soil just moist.

Humidity

Mist occasionally in very dry air; otherwise not critical.

Feeding

Heavy feeder: weak fertilizer every couple of waterings in spring/summer. No feeding in winter or for 3–6 months after repotting.

Temperature

10–29°C/50–85°F. Can tolerate 4.5°C/40°F briefly if kept dry. Above 29°C leaves lose turgidity.

Repotting

Repot when growth stops due to pot-bound roots. Either move up a pot size or top-dress (replace top few inches of soil).

Propagation

Stem cuttings (10–15 cm) with one leaf. Let sap dry, then root in gritty compost or perlite with bottom heat. Best in summer.

Speed of Growth

Moderately fast. Summering outdoors boosts growth, but avoid wet, intense sun.

Height / Spread

Up to 3 m (9 ft) in ideal conditions. Pruning central stem encourages bushier, wider growth (max spread ~1 m/3 ft).

Flowers

Insignificant; new leaves emerge from colorful (often red) sheaths.

Anything Else?

Dust leaves regularly with a damp cloth. Leaf shine products can be used for gloss.
