JRP propagation

[Bunjeh]

Better to root cuttings or air layer JRPs? Just confirmed that the two large pines in my yard are indeed JRP so I want to try getting some material from them.

As an air layer, the 'cutting' is supplied water and minerals by the mother tree (via the xylem/wood that remains intact in layering). As a cutting, it is on its own and praying for roots.

Soft wood cannot be layered, but softwood cuttings may develop roots. Otherwise, the harder it is to root the better are the odds that layering is THE way.

I agree that air layering is the best way to get a new plant started from the one the air layer is produced from! I have done many gardenias & find them easy to air layer. Azaleas are harder & do best with layering the "old fashioned way" by putting part of a long limb under the soil around the azalea & letting roots develop, then removing it & putting in a nursery pot in a good soil, as is done with air layering, to let the roots grow extensively before making it into a bonsai or planting it in the yard. There are a number of sites on google showing the process of air layering.

Is there anyone out there that has successfully air layered a pine? You can see it done with JBP on Muranaka's blog but that is the only place I have seen any proof of success. Everything else ends with the branch dying or you never hear if there was success.

I would recommend collecting cones this fall and growing a batch from seed next spring.

Well see it here. I haven't tried air layering a JRP yet; I don't have one in my possession. I try to air layer a JBP every few years. I'm trying one on a large 4-5inch trunk this year.
