Bonsai Seedling Repotting

[Winnie1]

I have some 5 week old bonsai seedlings I planted from seed. I want to transfer them into their own pot as I dont think they have enough room to grow. There are about 3 silk mimosas in one small pot (mimosas are about 4-5 inches in height), and I have 3 flame seedlings that are about 6 inches in height. Is it too early to transfer each of them into their own pot? They're growing so close to each other and I don't think they have enough food source in the pot to survive if I don't transfer them. Any advice will be appreciated. Thank you.

Hello. I'm located in the U.S. North East.

I would transfer them now if you want separate trees. Then place in shade for about a week and slowly move to full sun.
Or you can grow them as a clump or forest style.

Thanks. I should have mentioned that I'm growing them indoors (from seed). Do you recommend me transfer these into individual pots and use bonsai soil? Thanks, I'm new to this and and grateful for your response.

Seedlings can be transplanted any time after they are big enough to handle - usually after the first real leaves open. Yours are fine to transplant.
What sort of pot is a perennial question.
Smaller pots and 'bonsai pots' can really restrict growth so it can take many years to grow a decent trunk. Slightly larger pots allow the seedlings to grow more so the trunks will develop quicker. larger pots are generally easier to maintain as they don't dry out too quick. The choice between smaller, pretty pots and better development is up to you.

There's no problem bare rooting small seedlings like these when you transplant. Many of us routinely cut the roots at the same time to encourage better lateral roots instead of deep tap roots. seedlings are generally very resilient and can cope with quite severe root pruning at this stage so don't be worried about damaging roots when you separate and pot these on.

Looks like the BRT are getting very tall and lanky. Usually the result of not enough light. I'm sure they would appreciate a sunnier position or some grow lights.

Food source for any potted plant is entirely up to the grower. It's called fertilizer and you'll need to fertilize your babies every 3-4 weeks as potted indoor plants to maintain good health.
