How long to wait before repotting?

[itsnhan]

I've recently gotten into bonsai and I acquired a really young (maybe a year old) maple, as well as a schefflera. The maple was repotted by the nursery but looking back at it, I should have just kept it in the original growing pot.

The schefflera is similar, I repotted it to switch to some more standard bonsai soil, but the pot it's in isn't really ideal. The tray underneath the pot is basically attached to it, so there's no easy way for me to wire it down. It isn't wobbling and it seems pretty firm.

I'm planning on just letting both grow over time and thicken up a ton before I do anything (the wiring was on the maple when I got it, but the main question I had is, considering they were both repotted recently, is it is it worth repotting within the same year if I would be able to swap it out to a better pot/soil (or grow in the ground) or should I wait until the subsequent year to make sure they recover

I've included the pictures of both (ignore the scuffed wiring on the schefflera, i removed it)

It is well worth adding a location to your personal profile. Things like repotting are strongly seasonal which means that appropriate times depend on where you live.

As to whether to repot in the same year, there's a whole lot of related info that may change the answer, like: When was the last repot actually done? (no timelines given apart from 'recently') How much root was removed in the original repot? How much space is available in the current pots? Where have they been kept since repotting? And many more.

The maple looks like the pot has plenty of room for growth for a year or 2 so I'd probably leave it as is. I doubt it will grow much faster if transferred to another container this year so some risk for little gain to repot.
The Schefflera seems to have less space compared to the size of the plant so a change of pot might achieve something there. Schefflera are tropicals so do much better when repotted in warmer weather when they are actually growing. They are also very, very resilient plants so should be able to cope with another repot in the same season. If you are in the North, I'd leave that one alone until next Summer then repot. If you are in tropics (probably unlikely if you also have a maple) or in Southern hemisphere (unlikely as the maple has no leaves in the photo) you could carefully repot now.

I'll update my location, I'm located in California in a 9b zone.

The maple was repotted maybe 4 weeks ago? and the scheff. about 1-2 weeks. I don't recall how much the maple had it's roots removed but I think it was fairly minimal, the scheff. had minimal removed also besides any that were lost from knocking the old soil out, it was mostly just a soil change in the same pot. The maple is kept outside 24/7 and the scheff. is about 50/50 outdoors and indoors. I think the maple has a lot of space left in this pot, and the scheff. roots didn't seem like they were curling

I was also thinking about just leaving the maple there until the next year and was considering waiting until spring or summer for the scheff. repotting. Just wanted a more experienced opinion incase there was benefit to repotting despite it being recently repotted, but from what it sounds like, I'll just leave them for a while

Thanks for the extra info. I suspected minimal root removal as most beginners tend to be quite conservative with repotting.

Given that he maple is now essentially dormant it is unlikely it has grown any new roots so could safely be repotted again now if you consider that necessary.
1-2 weeks is usually too soon for new roots to begin so the Shefflera could also be moved again but, given the time of year, going into winter, I'd wait for late Spring or early Summer unless there is an urgent need to repot now.

I can't see any benefit to repotting now and several possible drawbacks.
One of the things we quickly learn is to work with the trees in their cycles rather than our own whims so agree with let them be until next season.
