The constant care that bonsai trees receive allows them to live years longer than their natural counterparts. There are two different types of bonsai placement: outside and inside.

Actually, there are no inside types of bonsai unless the conditions inside a house are those which allow this little tree to live.  House bonsai are the species that cannot handle freezing, like the ficus, carmona, Sageretia Seri, etc.

The bonsai's adaptation to the inside of a house depends on the environmental conditions, such as light, temperature, humidity, etc. With respect to the light, you can say that it is the most important element for the growth of bonsai.  Therefore, you must try to always situate the bonsai close to a window with ample light.

To avoid dehydration in your bonsai, you should maintain an environmental humidity level of 50% at a minimum.  The higher the temperature, the greater the humidity level should be. It is important to point out that house bonsai cannot handle drafts.

Outside bonsai, as their name suggests, need the same conditions as trees living in nature. As a general rule, place them in sunny areas, although, if the summers reach elevated temperatures, give them shelter from the sun and wind to avoid burning the leaves.

In terms of temperature, it is recommended to protect bonsai from frost.  Bonsai, to remain dormant over the winter, need a temperature that oscillates between 0º and 5ºC. Bonsai, living in a reduced space, need periodic watering.  The rule is to water them when the surface of the earth is dry.   It is advisable to water them with rain water.  If that is not possible, a trick is to allow water from the tap to sit out for 5 or 6 days in a container to eliminate the problem of chlorine spots.

On top of watering, bonsai need to be sprayed to eliminate dirt and dust that can collect on their leaves.
