I have an Adriatic JH in a 10 oz cup in sphagnum moss. I actually started this in a cloner. But the roots stalled in the cloner so I moved it into a  tupperware with sphagnum moss. The roots exploded but it started pushing green growth also. And it was leggy and pale so I then put it in a 10 oz cup using the two cup method. Been in the two cup for about 20 days. I did a kind of crappy job putting it in the cup. There is a lot of air in the bottom. Anyway I think it is time to move it to a larger container with some perlite and soil mix. There is really no way I think the roots can be separated from the sphagnum. How does one repot this? Any tricks? It seems odd to have this sphagnum moss in the middle of denser media in a container. But I can't see how to infiltrate it.

I would use coir and hold the cutting with the moss in a pot and add coir. water. Dont pack down.

" There is really no way ... " may not be true. Use a little or more patience and remove as much Sphagnum moss as you can. Then gently spread the root over an inch or more of soil mix in the bottom of a cup/pot and drop granular soil mix over it. The roots will fin their way out of the remaining Sphagnum moss through the moist soil mix.

I have also done by shaking the roots in a pot of water to dislodge some of the Sphagnum moss from the roots and then planted.

Wait for better suggestions as they come. Good luck.

  Here is the cutting. I was able to separate almost all the sphagnum from the roots. There was some loss of some fine roots. Inevitable. The one leaf looks chlorotic. I separated on the 11th (3 days ago). I sprayed the leaves with 1/2 Tsp MG per gallon of water on the 11th and 12th. The leaves  look like they have some kind of fungal infection. See the small holes? Should I leave it alone?, treat it with copper fungicide? move it out of the bin so it doesn't infect other plants? Thoughts? Thank you. I would really like this one to live since it is my last cutting of Adriatic JH

Don't worry it will survive, very hopefully.
If by any chance it did not survive, there is always another cutting of Adriatic JH available.
