Cork bark black pine from graft – follow up

February 27, 2015 by Jonas Dupuich

Two years ago, I started a few cork bark black pines by grafting (See “Creating cork bark black pine“). The grafts took, and that fall I began reducing the foliage on the host tree.

Now, one year later, it’s time to repeat the process. Both the scions and their hosts grew well last year, so I need to further reduce the regular black pine foliage to encourage the cork bark foliage.

I began by reducing the branches, leaving only one shoot on each tree. I then removed some needles. When there were branches growing above the scion that might shade it, I removed these branches first. The idea is to slow down the host tree and to provide the scion with as much sunshine as possible. Here’s what the process looked like for three young trees.

I left the grafting tape in place when I removed the grafting bag as it can help keep the scion in place while the union strengthens.

With the branches out of the way, I removed all of the old needles and a few new needles from the last remaining original shoot.

Here’s the same process repeated for two more trees.

Once the the cutback and clean-up was done, I repotted the trees – details next time.

    What’s the variety? I’ve been grafting nishiki kuromatsu for at least 5 years now, just wondering.

      It’s the same one – Nishiki Matsu, cork bark black pine.
