Ficus bonsai are ideally suited for indoor bonsai. There are many different varieties that are natural dwarfs. These varieties have very small leaves and slow growth habits. There are many varieties of ficus including narrow-leaf ficus, dwarf ficus, and weeping ficus. Ficus bonsai should be kept indoors all year round. With a few simple guidelines your Ficus bonsai can be grown without difficulty.

Watering 

Ficus bonsai, as with most bonsai, like to dry out between waterings. Feel the soil every day. If there is a rock in the planting lift it up and feel under it, otherwise, just stick your finger about a half of an inch to an inch into the soil. If the soil feels dry, water your bonsai. Never let your bonsai go totally dry for extended periods!!! The best way to water your bonsai is to soak it in a sink or container of water up to the trunk for about 5-10 minutes. Then allow it to drain. If top watering your bonsai, water, wait a few minutes, and water again. Repeat this several times to insure that your bonsai has received a thorough watering. Eventually you will be able to determine a watering schedule that meets your climate conditions..

Light

Ficus bonsai grow well in either direct or indirect sunlight. We prefer to grow Ficus in shady areas, out of the hot afternoon sun. Sometimes the direct afternoon sun can burn delicate leaves, especially when shining through a household window. Direct morning sunlight is great for almost all bonsai because of its low intensity. We have also found that most types of Ficus grow well under supplemental lighting sources, such as grow lights.
 

Repotting

Ficus bonsai should be repotted about every two years, although they should be checked every year. The best time to repot Ficus is in the early spring. After repotting, water thoroughly and keep the plant in a shady location for several weeks so that new roots may grow.

Winter Care

Ficus bonsai should be kept indoors during the winter months. Display them in a sunny spot that does not go below 60 degrees Fahrenheit. Some leaf drop may occur if the temperatures are too cool or if your Ficus bonsai is placed in a cold drafty environment, such as a location close to an outside door. Although some leaf drop is normal, measures should be taken to protect your Ficus from the cold.
