Tips on Care and Sunlight Exposure for Rubber Plants

Rubber plants can grow up to 40 feet tall with leaves 8 to 12 inches in length. Most indoor plants, however, do not reach more than 10 feet tall. This plant, with its glossy leaves, makes an attractive decoration in a room. Proper care will keep it thriving for a long time.


Rubber plants do well in many soil conditions. A good potting soil is sufficient, as long as it is well drained. Cal Lemke of the University of Oklahoma Department of Botany and Microbiology suggests using two parts peat moss, one part loam and one part sand or perlite. Also make sure the pot has good drainage.

Light & Temperature

Rubber plants do best in bright light, but can adapt to lower levels of light. Placing the plant in an east- or south-facing window will give the plant sufficient light. Ideally, rubber plants like daytime temperatures between 75 and 80 degrees Fahrenheit and nighttime temperatures between 60 and 65 degrees.


Like all other plants, rubber plants need water. Water deeply and let the soil dry out slightly before watering again. In the winter, decrease the watering frequency to once every two weeks, allowing the plant to go dormant.


During the growing season, plants need fertilizer to flourish. For plants in bright light, apply a water-soluble houseplant fertilizer once every two months. In lower light, apply once every four months. Stop fertilizing in the winter months, allowing the rubber plant to go dormant.

Other Maintenance

Rubber plants can grow tall indoors. They may need staking to stay upright. You may also prune them if they get out of hand. Wipe any dust off of leaves with a damp cloth or tissue to keep them shining and the plant healthy.
