Please forgive my ignorance, I received a grow from seed kit last October, with very minimal instruction, and after three months in the fridge I have potted my seeds. This is where the instruction ends.
I have some shoots, roughly 2” in length, currently In biodegradable pots. Now I am aware that at some point these will need to be repotted and I read somewhere that the roots will need trimming. Any advise as to when I should be doing this and what sort of pot they should go in to, will be greatfully received.
Thank you very much.

Hi and welcome te the empire.

Hm.. grow a bonsai from seed is a bit of a scam i am afraid. Bonsaiseed does not exist.beffectively you have very expensive treeseeds.

For now focus on it staying alive. If you have a healthy plant in summer you can consider other things. But if you are now in wintet, this is not a good time to have seeds germinate. So focus on keeping it alive. Lots of sun. Not letting iit fully dry out. Yet letting the soil dry out enough to avoid damping off..

Haha, yeah, I understand there isn’t such a thing as bonsai seed.
I timed it so they would be getting potted close to the beginning of spring.
So, as long as I can keep my trees alive at this stage, what are the next signs that I have to intervene, repotting, trimming roots etc?
Just so I know what I’m looking out for.
Thanks very much for the reply.

There are loads of choices for you to male. Most of them are personal preference. On my website Inhave a lot of articles about growing stuff. Take a look there.

Main thongs are rootspread, trunk size and shape. That will be the first few years..

Decide upon ground growing vss pot growong. Sacrifice branches vss trunk chops.
