You may look into Leatherback's website guide on the subject.

Thanks for the link! I was there before to get some info and it’s really useful site. I’ll ask the nursery when they repotted the last time, but looks like it’s fine for now. I’ll manipulate with sacrifice branches in the first year or two to thicken here-there.

Thank you for the warning, Auk. I choose the species on purpose, cause I like to think about myself like “not your average rookie”. I don’t care if I read somewhere that I need watering like blabla or fertilizing like blabla. I observe the tree instead.
I won’t touch now. I wait that he starts the Serissa Migration Ritual, and when it’s over, slowly I’ll start to working with him, but before that, I’ll buy some mallsai to get some practice.

I thought to start to use a 6500K light or even a specific grow light to give more support. Someone have experience with bonsai + artificial light?

About the placement : I got it form a local nursery, which is 5 mins by car from my home. The position of the Serissas in their shelf was exactly the same (SE) where I placed, just we live in a bit higher altitude. Like this I try to reduce the stress.

My concern is about the humidity and temperature. I have a reptile room where those are perfect, but the air cleaner can cause problems, and no natural light there. If nothing else helps, I’ll free up a terrarium and give a proper setup with heating and constant hygro.

In which time interval they start to drop the leaves after moving?
