Live Vein Identification
« on: June 25, 2015, 07:57 AM »
I have heard the idea of finding the live vein when deciding on where to create shari.
But how do you identify the live vein?
I thought the entire undamaged bark structure is the "live vein."
So is there a section within the bark that is more live than the rest of the bark?

The concept of "veins" for plants is largely an abstract thought.  It also applies mostly to junipers, and in junipers to quite old trees.  (I can hear the hackles rising around the world.)

If you are working with a youngish nursery plant, simply avoid removing bark and cambium for any distance directly below an important branch.  The tree will redirect its circulation around that spot. 

On older trees, you can often see a linear (vertical) swelling of the bark that shows where circulation is most strongly developed, but slow, careful development can let you work around that. 

What it boils down to, of course, is experience being the best teacher, so don't experiment with important trees.

Yes, a young plant with vigorous growth, you can remove up to 50% cambium.  Key is to always start the new deadwood on a side of the juniper as it makes the base of the tree thicker as the LV expands.

On a yamadori, you identify the deadwood, and then slowly work your way towards the LV with a small chisel till you find the white leading edge of the LV and go from there.  But before this, identify which LV's are alive and what branches they support as this helps you have an rough idea of where you can expose or expand the LV safely.

Good luck,
Chris

Seems like if you made the deadwood start in the middle (from the front), the ever-growing live vein would take on more visual weight growing to the sides and broadening the thickness from the front.

Exact opposite Wayne.  Whenever you reduce live veins, the remaining lv will increase in size.  Therefore, keeping the lv on the sides, it will in time make the base wider.

It starts out like you're disagreeing with me, but it reads like we're saying the same thing.
