In discussing and reading about Bonsai, I keep running across the term training pot, what is it?
Mature and finished Bonsai are displayed in ceramic pots, while Bonsai trees in training, are placed into training pots, which are either plastic, in the case of smaller trees, or mica pots for the larger trees. These are considerable less expensive than ceramic pots. The first training pots are generally rectangle in shape and 4, 6, or 8 inches in length, and 3 to 4 inches deep. The shape is similar to that of a traditional Bonsai pot. Larger trees are generally placed into mica pots, which are heavier and larger. The mica pots can be anywhere from 8 to 24 inches long, both rectangular and oval in shape, and 3 to 6 inches deep. The mica pots are made from a combination of mica and plastic, and are very sturdy. After saying all of this, any pot that is used for training purposes, and is not the final container for your Bonsai, can be considered a training pot.
