A Japanese White Pine

Yup, filling in the gaps slowly. It's getting more tea bags this weekend... come on, back budding!!

I like this tree a lot. Once the apex develops, I think it will be a great tree. It's already got age just needs a few more years in the barrel to mature like a fine whiskey

No, on its roots which was one major reason I purchased it.

I've got a few 3 year old JWP seedlings from Julian Adams and I've found that the roots are very finicky. He grows his pre-bonsai in a turface mix so I transplanted some of my JWP in 1:1:1 Akadama, Kiryu, Lava this spring. I had 1 of them die from root issues. the rest are growing well. I had 1 die from root rot last year but I made the mistake of putting it in Aoki blend... way too much akadama for a JWP.

I know they don't like wet feet at all, but in general have you found that JWP roots become stronger as the rootball becomes dense and mature?

I agree that Aoki has too much akadama. I add about 25% pumice to it.

I believe bigger trees can tolerate less then ideal husbandry more successfully then smaller. With that being said, I agree with Adair that Japanese white pine definitely prefer more pumice added to their mix then what do you get from a typical akadama-based blend. This one was repotted two winters ago and I deliberately used large sized aggregate as well.

Really like your tree! Looked really pretty in the pic you took for the ABS show that didn't happen. JWPs are so pretty. Is this one grafted to JBP? @vancehanna how's your JWP doing?

All of them are very happy! My single JWP of 30 + years is hopefully going to produce an layer for papa. I did the wire bind technique rather than cutting the cambium on February 1st and have been monitoring the moisture hoping it will produce roots by fall. Here she is on the bench, you’ll note the large poking branch and that’s hopefully what will become the rooted material.E432AFCF-1E53-4B3C-A04A-0F45E7CD85EB.jpeg

So what ratios of the soil components are you using for this tree?
 
Dav4 said:
I took the large akoi grain blend and added about 25% more large grained pumice.

No idea what akoi grain blend is or what it's components are.

I use the typical 1:1:1 akadama : lava : pumice.
How does you mix differ from that?

Aoki is like 80% Akadama 18% kiryu (similar to pumice) and 2 % lava rock. I've found as @Adair M and @Dav4 mentioned it almost has to be cut with more pumice or Kiryu.

Thanks
Yea I agree. Too high in akadama for a pine

Yes definitely. I learned it the hard way with a white pine seedling. Black pines will survive in it with good watering practices but won't thrive as well as they would in just a standard 1:1:1 mix I have found.

I have a slightly smaller JWP and I make my mix for that one... 1 part akadama, 1 part lava, and 2 parts pumice. It's a similar mix to what I use with my Rocky Mountain Junipers.

She looks beautiful! Sorry @Dav4 for hijacking your thread. 😄
 
Is be cautious about “plucking” JWP…..usually the old needles want to drop at the first sign of the frost so watch what your plucking unless you’re trying to shorten or reduce a branch….
