Mini bonzai root coming out the net

[TimIAm]

Just grab any small sized container that isn't too large. You can even use an instant noodle bowl and poke holes in it until it grows bigger. You just want a container that will drain well (and is not too big) so the tree is not constantly damp.

That appears to be a peat or coir pellet that its in. It doesn't look it's having any problems sending roots through or getting access to moisture, so I wouldn't bother removing from the pellet because you may damage the roots and those pellets are designed to disintegrate over time.

Just whack it in something slightly bigger and gently / firmly surround with the bonsai soil you bought. Right now in Sydney you can put it in full sun and you should be able to just water it once a day. I like to water my trees in the morning during winter as I know they will have enough to get through the sunny part of the day.

You can get a slow release fertiliser. Which you will only need a small amount and likely won't need to replace for another six months as it doesn't break down as fast in colder months. I prefer Osmocote Plus Organics which you can get at most grocery stores or the big shed. It won't need much more than that for the first year. Although some people might suggest dynamic lifter or Seasol or other stuff, please yourself.

Don't cut the little root off. As mentioned, the pellet is designed to break down as the tree grows.

Although it is out of season, this is Sydney and we can get away with lots of stuff out of season. However, as mentioned by @leatherback "the species might have trouble with your dry & hot summers." I have had trouble growing Spruce as bonsai in the past and I tend to avoid some colder trees and prefer tropicals and other trees that grow well locally.

with trees that young, you can do however you like, as long as you are gentle with the roots. just remove any old soil that you can easily remove



have a pot with drainage holes. water, when the top few centimeters dry out. water a lot to make sure everything is wet, but also make sure that all the excess water can easily drain out of the pot. you don't need to mist the foliage.

Thanks!
Should I put them in shady sunlight
Or direct full sunlight? as it does get quite warm in the sun

They should be fine with full sunlight during our winter months. However in your pic you have it next to what appears to be a glass door. So when we move to summer you wouldn't want to have it sitting there, then you can move it to part shade.

Just be careful because typically you want the edge of the top of the pot to be level with the base of the plant or seedling because the pot prevents the soil from drying out. With the top up like that the soil will be drying out from all sides. Don't want to be a pain, but can you squish it in a bit more without damaging the roots or suggest getting a slightly taller container and put extra soil around the peat pellet. z
