Julian Adams has been propagating these JWP for years. He is in Virginia.

I have not mentioned Zushio but definitely some posts showing cuttings of other pines on Shibui Bonsai
Zushio has always been propagated by cuttings and, of course, must be grown asexually to retain the genetics of the cultivar. Fortunately it happens to be a cultivar that strikes relatively well.

I think it was a JWP post, not a Zushio, I thought most Zushio's in the US were grafted? I love the look of JWP, but I can't grow them in my region.

Julian Adams has basically given up growing Zuisho from cuttings. Most of his trees are airlayers. I've talked to Adair and Boon, neither of which have had any luck propagating Zuisho from cuttings. (I think Boon took cuttings from Adair's tree.)
There's a series that ran thru International Bonsai in the 80s or 90s. It was long. I don't remember exactly, but want to say it was like 50 parts, detailing all aspects, by one of the pioneers of Zuisho. I think the percentages claimed in the rooting were akin to the guy who grew shohin jbp from seedling-cuttings in 6 years: overstated. Nobody else that I'm familiar with can claim similar success ...within at least an order of magnitude.

In the video, they say that success rate is 10%. Also, that they use just the very tip of the candle to have better chances of success. They also leave the pot with the cuttings on it inside that water tub with rooting hormone added for at least 24 hrs. I guess for someone that will develop this trees and sell them, all this work really makes sense, for us mere-mortals, it is a lot of work for the small reward.

At 10%, the benefit of cutting propagation dwindles. That being, volume. At those percentages, the success rate of airlayers makes its lack of volume less of a problem.

is Zushio the smallest foliage white pine out there? Seriously compact little pads there.

Kokonoe may be a bit smaller, but it’s negligible. Zuisho is bluer in color, and is a really cool little cultivar.
I have tried Zuisho cuttings with zero success. It’s a seriously long term project…that is if you can get any to grow to start with.

I can see why people try though, just a glance at those trees and I immediately say to myself- "I WANT IT" lol

They just uploaded an air-layer Zushio video today. From what I read, it took 2 years to root.

i just saw that one this morning, the tissue paper (he mentions chili paper as well) with root hormone 'joint roll' technique to wrap the air layer site is very interesting as a way of introducing 'time released' hormone into the wound/bag....learned something new....

I gave this a try with "Aoi" shortly after this video came out.
I followed the method in the Q video to a T -- terracotta pot, cuttings in rows, start from the middle, sharp clean grafting knife, 3 sizes of akadama, flood the tub, 3 days of soaking in hormone, super-shady spot in and amongst other trees in the garden. I've had some recent luck in getting shore pine cuttings to produce callus at the cut tips and to even push some needles after sitting on heat during the winter, so here's hoping. Wish me luck. Good luck to anyone else trying.

I separated a quite large (~1ft tall, bushy) lodgepole pine air layer last year after about 26-28 months or so. I had lots of roots at that point, visibly pressed against the transparent hard plastic of the nut jar I'd used as a layering pot. I inspected quite often during that entire stint, and saw no signs of roots for well over a year. I forget who said it originally (maybe Ryan Neil?) , but someone said that the roots don't really start to grow until the second year. After trying it with lodgepole, I definitely believe it. I have no evidence to support the following claim but I personally believe this should work with any pine. Maybe I should try cloning JWP "aoi".

Thank you for sharing this video.
It's interesting how he uses a tissue as a permeable membrane to wrap cloning powder around the lower portion of the air-layer location.
