scotland, United Kingdom

I have just got a large juniper, semi prostate kind- from work, it has 2 trunks and on one, someone was going to take an air layer from it.
the layer has been on for 3 or 4 weeks but no roots are showing yet.
I have potted it just now, some roots have been trimmed and i,m going to prune it.
what will happen if I remove the cover and moss from the air layer? will that trunk die or will the bark regrow? or should I leave it then remove that trunk?
