How often should a bonsai be watered indoors during the winter?
Water bonsai plants frequently. In their shallow pots, with limited root space, they can easily dry out. As soon as the soil surface begins to dry, place the pot in a baking pan filled with about an inch of water. Leave the pot standing in the water until the soil surface becomes moistened. In between waterings, mist the bonsai s leaves with water from a spray bottle.
