I recently aquired a Burning Bush Bonsia (10 years old) from a freind who is downsizing his collection. The tree is in great health, and was previosuly potted with traditional 1:1:1 of : Akadama, pumice, and lava rock soil mixture as is often recommeneded on this site as well.
It has become root bound and will need to be repotted. My friend mentioned that if moved to a bigger pot the soil mixture may need to be adjusted for more drainage.
For this type of tree is should i continue to use the traditional 1:1:1 of : Akadama, pumice, and lava rock soil mixture?
I have used this mixture for all my previous and current bonsai without issue, however i have never owned a Burning Bush, so any additional types from any owners would be great!
