Rubber plants grow well in many different conditions and will grow to eight to 10 foot tall. This is why they are a favored plant in many offices where growing situations are often not the best. They can take a little abuse and still look good.
Rubber plants prefer warm temperatures. They adapt quickly to household and office temperatures, but thrive in conditions that maintain a daytime temperature of 80 degrees Fahrenheit or more, and a nighttime temperature of 65 degrees. If possible a natural eastern lighting is best.
Rubber plants require adequate soil moisture, but over-soaking the soil will cause major problems. To avoid over-soaking, use pots that drain. If the pot is set in a saucer, discard the excess water after each watering. Pebbles in the plants saucer will help if there is too much water by raising the plant above the water and it will also add humidity around the plant.
Re-pot the plant when it requires re-watering within one to three days or if it becomes too large for its container. You can use a commercially available potting soil. I use a potting soil that is more porous than some to make sure I have good drainage.
Apply a soluble fertilizer suitable for houseplants once every two months if the plant is exposed to high light, and once every four months in medium-lit areas. This rule of thumb does not apply during the winter months (January and February) when fertilizing is not required. The plant is in a natural resting period at this time.
Rubber plants are healthy and happy if their leaves retain a glossy appearance. Gently wipe leaves with a moist tissue or soft cloth to remove dust. This improves the appearance of the plants and also helps the plant leaves to breath better.
You can remove stubborn stains on plant leaves by adding a small amount of hand soap to the water.
