How to Care for Rubber Tree

The Rubber Tree (Ficus elastica) is a popular, easy-care houseplant grown for its large, glossy, leathery leaves and upright, tree-like form. With bright indirect light and consistent care it can grow into an impressive indoor specimen several feet tall.

Light

Rubber Trees do best in bright, indirect light near an east-facing window or a few feet back from a brighter one. They tolerate some direct morning sun, but harsh midday sun can scorch the leaves. In low light, growth slows, new leaves shrink, and variegated forms lose their color, so give variegated cultivars especially bright light. Rotate the plant periodically for even growth.

Water

Water when the top inch of soil feels dry, then water thoroughly until it drains from the bottom. Let excess drain away and never let the pot sit in water. Rubber Trees dislike both drought stress, which causes leaf drop, and constant sogginess, which leads to root rot and yellowing leaves. Reduce watering in the darker, cooler months when the plant uses less.

Soil & Potting

Use a well-draining, aerated potting mix; a general houseplant mix amended with perlite, bark, or coarse sand works well. Choose a pot with drainage holes. These plants prefer to be slightly snug in their container and grow steadily in a mix that holds some moisture but drains freely.

Humidity & Temperature

Average room temperatures of about 60-75F (16-24C) suit it well, and it should be kept away from cold drafts, heating vents, and sudden temperature swings, which trigger leaf drop. It tolerates ordinary household humidity but appreciates moderate humidity; occasional misting or a nearby humidifier keeps the foliage looking its best in dry indoor air.

Feeding

Feed monthly during spring and summer with a balanced, diluted liquid houseplant fertilizer. Ficus elastica is a moderate feeder; avoid overfeeding, which can cause salt buildup and leaf-tip burn. Stop or greatly reduce feeding in fall and winter when growth naturally slows.

Propagation

Propagate from stem-tip cuttings or by air layering. For cuttings, take a section with a couple of leaves, let the cut milky sap dry, then root it in moist mix or water in a warm, bright spot. Air layering is reliable for taller, leggy plants: wound the stem, wrap it with moist sphagnum moss and plastic until roots form, then sever and pot up the new plant.

Repotting / Pruning

Repot every couple of years in spring, moving up one pot size when roots fill the container. To manage height and encourage branching, prune the top or leggy stems in spring; the plant releases milky sap when cut, so handle cuts carefully and wipe tools. Pruning just above a leaf node encourages new shoots below the cut. Wipe the leaves periodically with a damp cloth to remove dust and keep them glossy.

Common Problems & Pests

Leaf drop is the most common complaint, usually caused by overwatering, cold drafts, or a sudden change in conditions. Yellowing lower leaves often signal overwatering, while brown crispy edges suggest underwatering or low humidity. Watch for scale, mealybugs, and spider mites, especially in dry air; treat with insecticidal soap or by wiping the leaves. Consistent conditions are the key to a happy Rubber Tree.

Seasonal Care Tips

In spring and summer, water more regularly, feed monthly, and do any repotting or pruning while the plant is actively growing. In fall and winter, cut back on water, pause fertilizing, keep the plant warm and away from cold windows, and provide as much light as possible during the short days.
