Both of my elms are indoors and in Akadama exclusively. On the larch planting, Akadama is great, but it will need to be outside.

uzeyr,

I've always used materials that are available to me without resorting to importing. I have used Turface, Haydite and lava rock. Have you seen Harry's page on using kitty litter or absorbents for bonsai medium?
https://www.bonsai4me.com/Basics/Basicscatlitter.htm
https://www.bonsai4me.com/Basics/Basics_Soils.html

Be careful about using the old soil. Mixing finely textured materials with coarse ones has the effect of reducing drainage because the fines work their way between the large particles and slow drainage. By the same token, be sure to sift the Akadama through a screen in order to remove the fines that will surely be included in the bag.

If you feel that you need an organic component use something with texture such as Pine or Fir bark. Some growers in hot climates include some chopped sphagnum moss in their pots in order to help retain moisture but in your climate I doubt that it will be necessary. Please note that I am not referring to the finely textured peat moss that is sold in bales at nurseries.

uzeyr,

If the Larches need re-potting go ahead and do it, you'll have to anyway, if not this year then next. I have my doubts about the old rule that states you should not fertilize newly transplanted trees. Read Brent's take on [url=https://www.evergreengardenworks.com/fertiliz.htm]fertilizing bonsai.[/url] And here is a [url=https://www.bonsai4me.com/SpeciesGuide/Larix.html]care sheet for Larches[/url] if you have not already seen it.

Yeah, watering more frequently will definitely be needed. Observe the soil carefully until you've got it down. Good news is that it is VERY easy to tell when Akadama needs watering.

As a rule of thumb, you generally want to fertilise when buds break on the tree.

You'll hear two takes on when to fertilise your newly potted tree though:

1) Fertilising your tree will burn the new roots. This will lead to the new roots dying, and an uphill struggle with your tree. Further to this, placing it in windy or sunny conditions will also add to the trauma so soon after a repot. Leave for 4 weeks or so before placing it in the open, and fertilising as normal when buds break.

2) However, as aforementioned by Gnome, Brent Walston's take is; why deprive your tree of nutrients and sunlight when it needs it most? Your tree needs to establish itself, and to do so, it needs nutrients and sunlight.
