A popular indoor tree is the weeping fig, also known as the ficus benjamina. The tree gets its name from its branches that tend to hang down when grown indoors, although some people claim the name comes from the tree's habit of weeping copious amounts of leaves onto the floor. Weeping fig trees are hardy indoor plants, but they do need specific care if they are to flourish.
Prepare a proper growing environment for the plant. Indoor fig trees, like most tropical plants, prefer well-drained soil composed of peat moss, bark and sand. A 10-inch pot will be sufficient to sustain a fig tree of up to 5 feet tall. Place the potted tree near a curtained window with southern exposure, as they grow best in bright, filtered light. Set the thermostat to range between 68 and 85 degrees. Although the tree can survive temperatures in the 40s and 50s, it will not thrive.
Keep the environment consistent. Indoor fig trees do not respond well to change. Changes in light, temperature and water will cause the tree to drop its leaves. Keep the soil moist but not soggy. Indoor fig trees rarely need fertilizer and can adjust to a wide range of water levels; the important thing is to keep the moisture level consistent and to not let the soil dry out between waterings. Just like people, indoor fig trees will consume more water during hot weather and will use less during cooler temperatures, so adjust your watering schedule accordingly.
