hi... im Derek, new to this site, does anyone know anything about aqua bonsai? I tried to research it online and found a Tokyo based company that did them, but they do not respond to email, and the site is partially down, so I suspect they are out of business
any info on how you can get a tree to grow in water with no substrate will be helpful
thanks

Hi and welcome. Here is the link with the info from this very site. Just a search button away
