An undemanding plant, ficus plants make great indoor additions. They are not prone to pests or to disease. What we find indoors in the United States now is generally an improved upon hybrid of those native to India and Southeast Asia. They are able to withstand a great deal of heat and sun while growing rapidly. Ficus do not tolerate cold temperatures well.
Plant the ficus in a pot large enough to promote future growth. Choose a decorative container, 18 to 24 inches deep and 12 to 18 inches in diameter. Place a sponge in the bottom of the pot over the drainage holes. Fill the pot with potting soil, leaving a 1-inch space at the top of the pot. Dig a hole in the center of the pot 12 to 18 inches deep. Place the ficus plant's root ball into the hole, and cover with soil. Firm the soil around the base of the ficus, ensuring the entire root system is underneath the soil.
Water the container well, allowing excess water to drain from the bottom of the pot. Apply an indoor plant fertilizer according to the label directions. Apply a layer of mulch around the base of the plant in the container.
Place the container in bright light in an area with high humidity. Mist the leaves with water from a spray bottle twice daily to encourage a moist environment. Run a humidifier in areas where the humidity level is low. Turn the pot once a week to provide an even amount of light to the entire plant and prevent it from leaning.
Water the container when the top 1 to 2 inches of soil has become dry. Provide enough water that the excess drains from the bottom of the pot. Allow the top layer of soil to dry between watering.
Fertilize the plant once a month with an indoor fertilizer. Apply according to the label directions. Do not fertilize in the winter months when the plant is dormant.
