I have done semi hardened new growth air layering on Rhododendron just as you have done your roses. Potting and further growing in semi shade is needed to build stronger root masses. In my care this leads to nicely rooted plants for planting in place the second or third year. I keep them potted until the new growth indicates strong roots. In my first experiment I had twenty five air layered semi hardened new growth Rhodonedndrons. The success factor was eighteen excellent, two questionable and five loses. Not bad at all for $14.95 plants. My pots were gallon size second hand food cans. My plastic was dry cleaner clothing bags. I did not use the black second cover.

The picture shows them some thirty five years later at the edge of our patio and property line.
