One of the most common indoor plants, the Ficus genus includes more than 800 different species and 2,000 cultivated varieties, all of which are plants and trees that are grown for their attractive foliage. The most commonly grown ficus trees are the rubber plant (Ficus elastica) and the Ficus benjamina. Because ficus trees are tropical and cannot tolerate temperatures below 40 to 50 degrees Fahrenheit, they're grown indoors in most climates. Ficus trees are known for their tolerance of low-light conditions and low-maintenance requirements.
Position your ficus tree in bright, filtered light, such as beside a southern- or western-exposure window with curtains or blinds. Ficus trees can tolerate low-light conditions quite well.
Maintain air temperatures around your ficus tree of 68 to 85 degrees Fahrenheit during the day and 60 to 65 degrees at night. Keep your ficus tree away from drafty areas and don't expose it to temperatures colder than 50 degrees.
Water your ficus tree once to three times per week, depending on your indoor environment, to keep the potting soil moist at all times but not soggy. Don't allow the potting mix to dry out between waterings, and pour water into the pot until it begins to drain from the bottom.
Feed your ficus tree with a water-soluble 10-10-10 or 20-20-20 NPK formula indoor plant fertilizer while the tree is actively growing, according to the instructions on the label. Most indoor ficus trees don't require fertilizers, but you can feed the ficus if it begins to lose its vigor.
