Pretty Fly for a Bonsai Guy
I don't think it's as common as the Ryan Neil video suggests.
Mine just turned straw colored, but never broke off.

It is easy enough to figure this out when it arises because of differences in the growth rates, since all growth occurs in the cambium.When a graft is going to fail will you see signs at the union first? Or will the tree die first without indication the graft is failing? I would think something would be noticeable at the union but have no experience with this occurring...yet
I don't mean to become overbearing. It just happens when I try to 'share'.Hmmm...that's a fairly complete statement.
up front (and, maybe, just left it at that).In brief, we expect to see a separation gap that progressively moves around the circumference of the graft union, accompanied by a corresponding decline in the vitality of the foliage canopy, though the decline in one area of the foliage canopy may be noted first). But, possibly the union just explodes, instead .
My Zuisho JWP did this. I have no idea if it was intensional or not. It had two sets of roots. The old JBP roots have now been removed.One option, if the graft is low, is to plant the pine deep enough to bury the union. As the graft union begins to fail, the scion may form roots at the union. If kept buried, you won't miss this opportunity. If the graft is high, it won't be possible to do this. When possible, once a young grafted tree is well established and growing, I try to air layer off a section that won't be needed for the grafted tree's design. Sometimes it works, sometimes not. My JBP cork bark pine air layering success rate is about 40 or 50 %. Ground layering is in progress on my Brocade.
They sure look like Ondae. As floppy as they may be, they do have at least one characteristic that is useful for bonsai. Falling branches work pretty well with this corker. Cascades also work well.This is the last 3 pics and as you can see they grow quite robust sprouts but put no energy into developing the wood to support this growth:
The tortoise shell bark variety is hard to find. One variety that has it is called Hachi Gen. You can get cuttings from Evergreen Gardenworks run by Brent Walston. I haven't seen actual tree size corkers, and don't know of any, so I can't answer your question. Maybe someone else can answer.
Telperion Farms in Lyons, OR. Wisdom to me would dictate wiring anything before any sign of bark development happens.Here's one. I've had it for a couple of years. It was marked down because the cultivar was unknown. It had a low graft and I'm a bit of a cheapskate so...View attachment 81968View attachment 81969
Now the questions. Any trick to wiring these without trashing the corking? How cold hardy are these? Normally I just put my hardy pine under the bench mulched in. But I may see -30 here. Potawotomi13, what nursery was that? Just in case I ever make it back over the hill.
