Containers

Every bonsai pot is equipped with drainage holes to enable the excess water to drain out. Each hole is typically covered with a plastic screen or mesh to prevent soil from escaping. Containers come in a variety of shapes and colors (glazed or unglazed). The ones with straight sides and sharp corners are generally better suited to formally presented plants, while oval or round containers might be used for plants with informal shapes. Most evergreen bonsai are placed in unglazed pots while decidous trees are planted in glazed pots. It is important that the color of the pot compliments the tree. Bonsai pots are produced all over the world, some are higher quality than others and some are highly collectable such as ancient Chinese or Japanese pots made in highly touted regions with experienced pot makers such as Tokoname, Japan. However, highly collectable pots are not just confined to Asia, European Artists such as Byran Albright and Gordon Duffett produce unique pots which Bonsai artists collect.

Pre-Bonsai material are often placed in "growing boxes" which are made from scraps of fenceboard or wood slats. These large boxes allow the roots to grow more freely and increase the vigor of the tree. The second stage after using a grow box is to plant the tree in a "training box" this is often smaller and helps to create a smaller dense root mass which can be more easily moved into a final presentation pot.
