Good Evening All,

For those of you that have or work on Japanese Cork Bark Black Pines does this tree go through the same candle and needle technique that the normal JBP Pinus thunbergii does? Thanks.

Rob, the answer is yes and no.

We candle corkbarks every other year. The bark develops better in the year the tree is not candled. So we give one year for needles, one year for bark.

Maybe BOON will post a picture of his big cork bark or near cork bark black pine from Mas, it wasn't decandes this year and it is amazingly dense- really spectacular growth.

Boon would you please?

Boon, this tree is remarkable. Therefore I am remarking on it.  Grin

Was this Mas' famous tree? I don't think I've seen it in your shop before. What a beatiful example it is. Thank you so much for showing it.

What a fantastic tree!  Looks great from all sides and doesn't look like a big green gumdrop Smiley

Thanks very much for sharing Boon!

Hi Chris,
This is not Mas' famous tree.  That old tree is at the Golden State Bonsai Collection at Lake Merritt(Golden State Bonsai collection North).  I no longer work on that tree.  I visited that tree several times.  It is like visiting an old friend.

This cork bark black pine used to belong to Mas' friend.  He said it grows from seed.  The tree is about 80 years old.  I think this tree is the oldest cork bark that is grown in the USA. 

It was yellow and weak when i got it.  In 2004, Mas' familiy asked me to pick a tree from the collection as a gift.  I picked this tree.  It was so yellow that Mas' son said 'Are you sure?  it may not make it. 

I took it home and repotted it.  Jonas (www.bonsaitonight.com) , my student, helped me repot this tree.  it took us 4 hours to finished the tedious work.  We are sure that the tree will survive.  After repotting, new buds started to grow but very small.  New needle was short but green.  A year later, old needle dropped new candles grew healthier.  I decandled the tree twice since i have it.  first time, it is to push new interior buds to grow and the second time in 2008 to get it ready for the show in Jan 2009. 

We changed the pot and showed it in Jan 2009.  Mas' son and his wife came to see the show.  They are happy to see this tree growing healthy.

This year, i let it grow freely until October.  John Callaway worked on it and John McDonald finished the work.  Both John have studied with me for a few years.  I trust them to work on my tree.

I tried to find the earlier picture of this tree before i work on it.  but i could not find it.

Thanks,
Boon

It seems that the original pot was far too shallow to support a tree of this magnitude, is this assumption correct? and if so why did the original owner relinquish the trees health in favour of aesthetics? which IMHO where imbalanced...

Rick,
As Mr. Imazumi aged, many of his trees lost some of their vigor. (As will happen to all of our trees if we don't come up with a plan for their care). Boon helped him a great deal. I am sure that before his health failed that this tree was as healthy as you could ask for, even in such a shallow pot.

Mas insisted to have that tree in that pot.  the reason is that that tree was a gift from his friend.  he felt that it should stay in that pot.  i helped him repot that tree  a couple times before i received it. Mas keep it alive all these years.  i wired it once in 2000. 

Scott Elser wired it 3 years ago during Intensive. 

thanks Chris,

Boon,

I am fascinated with this species. Any new pics of this tree? I'd love to see some if you have any.

Thanks,

Beautiful tree!  I personally prefer the "back" view as it appears to my eye to have a more graceful movement.  (I'm assuming Boon's 1st pic in post #3 is the front, and the third is the back.)   Of course, these are 2D pics, it might give a totally different impression in person.  Regardless, it's spectacular.  Virtually all the cork pines I've ever seen have been grafts.

Boon, is this tree susceptible to inverse taper that I've seen on so many cork pines...like in the area of the bends in the trunk, in say 10-20yrs?  Just curious.
