I have one of those ceramic self watering pots where there is one pot inside the other and the water is absorbed through the ceramic; however, will this be enough for my bonsai trees? I have a Golden gate ficus plant. I am also little worried about the drainage because the inner pot doesn’t seem to have any holes in the bottom, but it could be a possibility that it drains the same way it sucks the water. Also, if it will work for my bonsai, how much do I need to fill it up? Can I use self watering pots for Bonsai trees? Please advice. Thanks.
