For many people, the Chinese elm (ulma parviflora) is often their first bonsai tree. These trees are quite common and are often seen in shopping centers and are sold as "indoor bonsai." While Chinese elms can be grown indoors, they are more properly outdoor trees and benefit much more if they can live outdoors year round, provided that the winter temperatures do not go too far below freezing for extended periods. If winter temperatures get too cold (below -3C or 25F), then an unheated room or garage might be more appropriate for them.
Chinese elms, if they are grown indoor, will eventually lose their vigor and leaves will eventually drop off. This tree naturally loses its leaves each year because it is deciduous. They need a very good light source if grown indoors, e.g. a south or west facing window. They should be located as near the window as possible to maximize the available light. If maximum light is not available, a supplemental electric lighting source may also be needed.
The soil in a Chinese elm bonsai should be freely draining and it should be kept evenly moist at all times. Regular checking of the soil with your finger will insure that enough moisture is available to the tree's roots.
They can also benefit from having the pot placed on a tray beneath them to collect the excess runoff from your watering. This will create a micro-environment inthe vicinity of the tree that will have increased humidity. The tree should not be exposed to a heat blast from a furnace duct or heater since this dries the tree out too much.
But even with all the best care that can be provided indoors, the Chinese elm flourishes best when it is grown as an outdoor tree and one should always consider that ption first regardless of whether or not the retailer indicated that they are an indoor tree at the time of purchase.
