Despite the fact that they look pretty tough, bonsai trees can be quite picky with their water and light requirements.

When you bring a bonsai tree indoors it will require sufficient lighting to replace the natural sunlight that it would have been receiving outdoors. Your plant will also benefit if it is placed in a well ventilated area.

How frequently you water your bonsai will depend on what kind it is and the condition of its soil. There are some bonsai trees that require well watered soil, but others are able to survive with almost no moisture.

A bonsai plant will respond well to frequent misting as it soaks up the humidity. You can use a humidity tray, but be certain that your pot is placed on some small rocks or a stand, and not sitting directly in the water.

The indoor bonsai tree will still need to be regularly pruned and cut to maintain its appearance. Bonsais often appear changeless; however, they are definitely a living, growing tree. You need to repot your bonsai, whether it's indoors or out, every year to three years, depending on the variety. As well, you'll need to give proper maintenance to the branches in order to preserve its distinctive style.

In the wintertime, you'll likely have to reduce fertilization, depending on the type of bonsai you have. The reason is that some bonsai varieties go dormant at this time and don't require as much nutrition as they do in the warm seasons. Your indoor bonsai might not fully experience the whole cycle of seasons because it is in an artificial environment.

You need to be on the lookout for pests and other irregularities that might appear on your indoor bonsai tree. Since they're indoors, they will likely attract mites and spiders from the outside. Use a soft, damp cloth or brush to carefully clean the branches and leaves of an indoor bonsai.
