Hello Mirai community.
My plan for the oncomming spring is to put an acer air layer into a wooden box.
My question is, what soil type is best to use to promote as much growth as possible.
is a 1 : 1 : 1 akadama lava pumice ok, or are there better alternatives like only use pumice?
i find alot of soil mixes for refinement, but nothing for much growth.
I know that placing it in the field is best, but that is not an option.
The plan is to grow primary branches since there are none of them on the trunk.
I live in Belgium.
Thanks in advance.
PS: sorry for any spelling mistakes
