The subject of Bonsai Pots is extensive and we will be updating this area as we receive information.

In the mean time some sites that have done a sterling job of this are shown below as a link.

We also welcome information to include here so please us our contact form to start a discussion and hopefully we can include your information for reference. We would also like to start a "chop marks" and Signature" reference going forward so take a picture and send it through to be included.
many thanks!
