Question
What is a good basic mix for Bonsai potting compost? I understand it varies depending upon which tree you are growing.

Answer
Hi Alex,

This is one of the most frequently asked questions at BonsaiOutlet.com. And it's also one of the most widely debated subjects. Everyone seems to have their own mix.  

We blend our own soil, but for education purposes, you should consider reading the following articles.
