There are so many things to consider when choosing a Bonsai Pot, like the length, the depth, and the width of the pot. All these considerations play an important role when planting a Bonsai tree. I have even read books that contain all kinds of rules and guidelines for specific pot shapes and what shape tree should be planted in each.
In our experience (mine and my husband’s), we have discovered that although it helps to keep in mind certain guidelines, one should ultimately follow one’s own set of rules when choosing the right pot for your Bonsai. Simply go with what feels and looks right to YOU, and keep in mind the health of your Bonsai comes first.
