The indoor fig tree (Ficus) is one of the most common house plants in the world. The tree flourishes in tropical and temperate climates when grown outside as a patio or yard specimen. When grown indoors, the tree offers ideal hardiness and ease of care. The fig tree became a popular houseplant in the 1950s. Estimates claim there are over 800 species currently available, with 2,000 varieties in total. When grown indoors as a house plant, the fig tree will normally attain a height of 5 feet.
Plant the fig tree in well-drained potting soil. The tree enjoys a 50-percent peat moss mixture with a 50-percent potting soil. A large-sized fig tree that stands around 4 to 5 feet tall will do best if placed in a pot that is at least 10 inches or larger.
Place the fig tree in a sunny location. A south-facing window is ideal. The plant can also be grown under a skylight with ease.
Water the fig tree weekly. Keep the soil moist but not water-logged. The fig tree will enjoy a light, weekly misting with a handheld sprayer on its foliage. This helps remove dust and keep the plant healthy.
Fertilize once a month during spring and summer using a 20-20-20 balanced fertilizer. Follow the directions on the label for application instructions.
Place the ficus away from cold drafts. The ideal indoor temperatures is between 68 to 85 degrees F. Never subject the ficus to a temperature below 40 degrees F.
