Rubber Tree Plant

Rubber tree (Hevea brasiliensis), is of high commercial importance, as a source of natural rubber. However, rubber tree plants that are among the popular houseplants, have nothing to do with Hevea brasiliensis (genus Hevea). These plants are otherwise known as rubber fig, rubber bush, rubber plant, or Indian rubber bush, belongs to the fig genus, Ficus. Even these rubber tree plants (Ficus elastica) produce latex, which is sometimes used for making rubber, but is not a commercial source for the same. This sap can cause skin irritation and its ingestion can be dangerous too. It is said that these plants are among the oldest ones that are being grown as houseplants. They are not messy and it is not very difficult to grow them.

Tips to Grow Rubber Tree Plants

Natives to Northeast India and certain parts of Indonesia, rubber tree plants are now popular as houseplants, across the globe. In frost-free areas, this plant is often found as outdoor as well as indoor plants and they are mostly grown indoors, in places that are prone to frost. They have waxy, oblong leaves that are green with burgundy shades. In their natural habitat, these plants can grow up to 50 meters in height, but, you may start with a young plant that can be successfully grown indoors, to a maximum height of 10 feet.

• Even though, these trees are found to thrive in different soil conditions, it is always better to plant them in well-drained potting mix. Water the plant, as and when the soil gets dry. Repotting of a rubber tree plant can be done every other year or once in three years.
• These plants require warm spots, away from direct sunlight and so, place them in locations that can provide with five to six hours of bright, indirect light.
• For optimal growth, the temperature should be maintained between 55 to 75 degrees. You may even keep a tray with pebbles and water, beneath the pots, so as to maintain the humidity levels.
• Watering is another important aspect of rubber tree care. You must water them, only the soil gets dry. Even once a week watering is preferable. During winters, reduce the frequency to once in two weeks. Over watering or under watering may result in the rubber tree plant losing leaves.
• You may go for a phosphorous rich fertilizer (like 5-10-5 NPK), during the first two to three months of growth. Afterwards, try nitrogen-rich ones, like, 10-5-5 NPK, for its whole life. Feed the plants once a month, during spring and summer and during fall, reduce the frequency to once in two months.
• Pruning is very important, if you want an indoor plant with an average size. You may prune the plant during late spring or early summer. Pruning the central stem regularly promotes growth of branches, at the same time, controls its height. Cut off the stem, just above the node.

In short, rubber tree plant is a good choice for an indoor plant. You may also grow it outdoors. If you want a huge tree, refrain from pruning. Pruning regularly is good to maintain an average size plant. The above said is only a brief overview about rubber plant care. It will be better to gain more knowledge about growing these plants, before getting them. You may follow the instructions of a horticulturist, or else, contact the local nursery.
