7 month old flame tree Delonix regia

Was wondering when I should trim the roots down and repot. And any other tips you all might have


I’m also very new to the bonsai world but trying my best and doing a lot of research and having fun doing it!

I don’t know the first thing about the species, but if it’s tropical, repotting in summer when the tree is active is often appropriate. I’d also see about wiring the new shoots before they thicken up to the point where they are no longer flexible.
