Hi everyone,

   I had a small Chinese juniper from cutting that a friend gave to me. it was just a thin, straight trunk with new shoots on the sides. No photos of it at this stage.

   In 2014, I decided to re-plant it slanting in the same pot, use the bottom branch for a future "mame" or "shohin", and air-layer the rest. So I secured a wire around the branch that I wanted to air-layer, and in May 2015:

   August 2016. I had put the lot in a larger container with coarse pozzolane to make it more stable and keep some humidity around.

   The roots just went out on one side, in spite of my turning the tree regularly. So I refreshed the cut and applied some hormone on it before repotting it:

   This is about how the whole thing looked like when my friend gave me a cutting, a bit thinner though.

   And I still have the base for a "mame"  Cool
   
The base of the tree, which is actually the part I focused on:

I know! I should have cut the air-layer further up to make a "jin", but I preferred to stay on the safe side and cut it just under the pot because from what I've read here and there, it may not be the right period to mess with the roots of a juniper. But the air-layered part was quite wobbly in its transparent pot, so after a couple of days, I decided to repot it.

Back to the base: do you think I can repot it now?

I mean I'm really bad at conifers, especially junipers. But the temperatures have been in the 30s these days (30° Celsius), quite exceptional in this part if the world for this time of the year, they forecast 34 for Wednesday, and 25-27 in two weeks' time, early September! (but with some showers of rain this time).

Very well documented Alain and great base for the small tree.

I am sure there is a number of contradictory answers to your question.

In my oppinion - if the plant is strong, you do not cut too many roots and keep the plant in a spot with scattered sunlight and high humidity it should be OK to repot basicaly any time of the year - at least in my region 7b.  You have repotted  the top section anyway... Wink   Now as the mother plant is just after airlayer - I assume that it has received only a limited supply of nutrients from the lowest branch - I think it would be safer to leave it alone for this season and repot it only next spring.  

For sure I am not an expert on trees in pots - just a common sense.

Regarding your comment on the jin - you could have added the missing part using a wooden pin. It may sound like a tanuki but it works.
