I want to replant a new Juniper that I purchased so I checked out the beginner series video on soil. It looks like the best thing to do would be to purchase akadama, pumice and lava rock separately - then mix them together in a 1:1:1 ration. Does that sound correct?
Would anybody recommend a pre-mixed soil that would be Mirai approved? I’m kinda hesitant to buy all 3 individual rocks just yet since I don’t have very many bonsai starting out.
