Want to grow bonsai indoors? Temperature and dormancy requirements of certain species will imparct your success with indoor bonsai. Deciduous species of tree bonsai--such as elm--will drop their leaves, just as they would in fall and winter outdoors.
Give them some time in a dormant period outside, as temperatures cool in the fall, before transitioning them back indoors, which will trigger them to begin growing and leafing again. We all need a break sometimes!
