Should I or shouldn't I

Greetings guys andd gals

So had a very good growing season and things are still going strong iv got many tree saplings andd I'm just curious to know if I should do a bit of pruning and wiring or just let them grow big and strong for a few seasons before pruning and wiring I'll add attachments too show my trees in question got 4 flame trees, a pine and 3 / 4 possible zelkova Japanese elms

Thanks in advance

No, dont mess with small saplings. Just let them grow.

If you want your bonsai to have movement near the roots, the first year is the time to do it. Look into baby bending seedlings.
