The rubber plant is a popular ornamental plant from the Ficus genus. For the indoor grower, looking for a tree type plant species with attractive foliage which can grow from 1 ft to over 8 ft tall, this is an excellent choice. The rubber plant is all about having a small tree indoors with broad shiny attractive leaves. When this plant is about 1 – 2 ft tall, it is well suited to be sitting as a centerpiece on a table, on a shelf, or on a windowsill, but once it begins to grow above 3 ft it looks great standing next to a fireplace, television area or near door entrances (as longs as there are no cold drafts).
Temperature: Average room temperatures of 60 - 75°F (15 - 24°C are fine. Avoid lower than 55°F (12°C), sudden temperature drops and cold drafts.
Light: A nice brightly lit spot is ideal, without direct sunlight.
Watering: Water once the soil becomes slightly dry to the touch and make sure the pot has sufficient drainage holes to allow excess water to seep through. The worst thing you can do regarding watering is "give it too much".
Soil: A well-draining and well-aerated potting soil is needed. 1 part peat, 1 part pine bark, and 1 part coarse sand (or perlite) is a good mix.
