Air layering in situ

Curious. There are several collecting areas I have access to that have beautiful eastern red cedars growing along shale and other exposed outcroppings. In many instances the only accessible roots are the large structural roots that snake along the rock face until they disappear into the cracks. Is it possible and has anyone tried to air layer the exposed structural roots. I was thinking big black plastic bags filled with spaghnum moss left in place until they root. I would think with a large enough set of feeder roots, it would work. Just curious about people's thoughts.

I'm aware of the negative impressions people have about eastern red cedar. These are much different. They are twisted, old deadwood junipers. Many are outstanding.

I say go for it! Long as they won't be disturbed throughout.

I love the species. Better as bonsai than as sluggers! They are everywhere by me.

Are you close enough to the area to add water to the moss now and then? Is the root location in direct sun? If so the black will act as a heat sink and cook the moss/roots.

Just thinking, why not ground-layer the bottom of the trunk instead of the roots?

Not daily, but weekly or every other week.

Some are full sun. Was thinking the same thing. What about tin foil or white bags?
