Most trees and shrubs trained as bonsai originate in the temperate zone where the difference between summer and winter temperatures are quite dramatic.
These temperature swings trigger cyclical changes in the life cycles of these plants.
The cooling fall air causes them to go into dormancy. Winter's cold prepares them to bloom in the spring. The warming spring air causes them to break dormancy and begin another season of growth.
The constant warmth of the home will not suit these bonsai plants. These types of bonsai trees can be brought in for short periods of time but they need to spend the bulk of their lives outdoors in order to remain healthy.

Indoor Bonsai Care
Three things are especially important where caring for indoor bonsai is concerned: temperature, light, and humidity.
Tropical indoor bonsai like a hot house environment where the temperature never falls below 60 degrees F. (16 degrees C). These plants enjoy daytime temps in the neighborhood of 75 degrees F (24 degrees C). The temperature should fall by 5 degrees or so at night just as it does outdoors.
Subtropical bonsai species prefer a house that is cooler in the winter. 41-60 degrees F (5-12 C) is the proper range.
Staging these indoor bonsai in a window dressed with thermal drapes will help to supply the lower night temperatures they require. When the curtains are closed at night, the cool air will be trapped around the plants.
Subtropical indoor bonsai trees should not be set on top of or too near radiators. They will benefit from a summer vacation in a shady outdoor location that is protected from high winds. Bring them back inside when night temps begin to fall into the 40s F.
Some of these plants, azaleas for instance, enjoy a short dormancy period. They should be placed in a bright, cool room and kept nearly dry until spring.
How much light an indoor bonsai plant needs depends on the cultivar. Different species have different requirements. It is best to consult a growing guide for the type of bonsai indoor tree you are growing for the specifics.
Indoor bonsais receiving too little light will exhibit spindly growth and the spaces between the leaves will lengthen.
Indoor bonsai growing in a window, will get a lot more light than those growing just a few feet away. Keep the curtains open during the day. Even a white sheer greatly diminishes the light entering the room.
Plants can be placed away from windows if artificial light is supplied. Put the lights on a timer and run them for 10-15 hours per day.
