Rubber plants prefer warm temperatures. Although rubber plants adapt quickly to household and office temperatures, for best results, maintain a day-time temperature of 80 degrees Fahrenheit or more, and a night-time temperature of 65 degrees.
Rubber plants require adequate soil moisture, but over-soaking the soil will cause problems. To avoid over-soaking, use pots that drain. If the pot is set in a saucer, discard the excess water after each watering.
To ensure proper growth, place your rubber plant in a commercially available potting soil. Repot the plant when it requires re-watering on a daily basis, or if it becomes too large for its container. Apply a soluble fertilizer suitable for house plants once every two months if the plant is exposed to high light, and once every four months in medium-lit areas.
With proper care, rubber-plant leaves will retain a glossy appearance. Gently wipe leaves with a moist tissue or soft cloth to remove dust. To remove stubborn stains, add a small amount of hand soap to the water. To give leaves a shiny appearance, wipe them with a cloth moistened with leaf-shine products available at your favorite garden center or nursery.
