Some bonsai pots do not come with pre-drilled drainage holes. Select a shape and color that you personally find aesthetically pleasing. It’s important to visualize the bonsai before you buy the plant and bring it home. Then look around at the selection of plants and imagine what each plant would look like after it is pruned. Decide what size bonsai tools you would like before actually going out to select the plant. Bonsai trees can be as anywhere from miniature to large bonsai. Select the size of your bonsai. Some trees will require a lot of water during a hot summer while others are heat hardy. Other trees will not survive long in the freezing weather.
