Air layer Cork Bark Black PIne

[Beng]

Can it be done? I'm not talking a winged corker just a normal cork bark black pine. I don't know the specific variety. If it can whats the best time? I've heard summer but I would think that would cause excessive sap bleed.

Also what have you all found is the best time to do a drastic cut back on them, with the least ill effect on the tree. I'm talking taking a 4 foot tall tree and cutting it down to 1.5 feet high.

Thanks
Ben

I've done generic JBP on both old wood (ca 5 yrs) and last year's candles and JBP 'thunderhead' on old wood with no real difficulty other than it takes at least a calendar year, so I don't think it matters much when you start it. George Muranaka is a bit north of you, gets harvestable results in one growing season, including cork barks. You ought to go see him.

George Muranaka does a nice job of documenting his work with layering pines. Unfortunately, he appears to be having trouble with his blog currently (or maybe it's a new browser I'm using). But this is surely a good place to start, if you haven't already.

It was working fine this morning. I recall lots of sites, even bank's/broker's, would not work with IE9 when it first came out because of 'standards' issues. Firefox, Chrome, Safari for windows, and Opera all worked then (and are free).

I believe that George's airlayer are on new growth only- I may be wrong though.

You are correct, Bob. My point, though, is that layering last year's candle is not a necessary condition for success. George is amazingly open about what he is doing and it is all laid out in his blog (just click that underlined stuff - its a link to George's blog).

Thanks so much for posting this! I have read it is difficult/ near impossible to root a JBP on old wood. I am happy to see him accomplish it in the link.

I have tried some cuttings and most are still green after a couple months, but I have a tree I'd like to layer.
