Bonsaify | Fall Work on a Field Grown Japanese Black Pine in Middle Development: Pruning and Wiring



Eric revisits a large field grown Japanese black pine that he decandled in 2021.

00:00:38 This tree is in middle development and has some good taper in the trunk already, from 6 inches tapering down to 2.5-3 inches. Eric plans to remove the large sacrifice branch to further the tapering process and help heal a large scar that was created in 2019 from a large stub.

00:01:49 Pruning because Eric let the tree run this year. He will be removing some longer, larger branches to bring the tree back in and make the trunk look bigger. Eric will also remove the sacrifice branch for more distributed growth and to encourage lots of bud growth.

00:03:07 Eric discusses design decisions and overall tree health.

00:04:45 First branch cut back.

00:05:46 Second branch cut back because it has a too long and straight section, and cutting will improve branch taper.

00:07:23 Unhealthy looking branch and why Eric’s not worried.

00:08:07 Pulling last years’ needles from around the outside or bottom.

00:09:20 Looking at top and beginning formation or crown – removing sacrifice branch and stub.

00:12:16 Wiring to enable more decisions about branching.

00:14:18 Obvious cuts Eric needs to make and more wiring.

00:15:37 Rotating branch junctions for cleaner branch structure that’s easier to maintain.

00:16:35 Bald spot – bending longest section of top branch down and back to create good crown foundation.

00:19:34 Rotate down and watch bark to limit splits. Additional wire added for stabilization.

00:21:33 Quick spin to see from all angles. Eric set the structure for the primary and secondary branches in the lower part of the tree and now the primary branches on top of tree, laying the foundation for the crown.

  1. This is a beautiful black pine with a wonderful and powerful trunk! I think you did the best work with these branches,i very like this first styling and obviously the boxes will be filled with vegetation as well as the apex will take on that dome shape. Very compliments!👍👍👍

  2. I’m a pine nut and I’ve been watching you for a while.
    You do a good job clearly explaining principles and tasks; you have a new subscriber here!
    God bless

  3. Thanks for all your black pine videos. Best and most informative videos on YouTube. Black pines are the most beautiful trees in bonsai but I would say the hardest to keep healthy. It’s not easy to find detail instructions on how to maintain and develop them thanks for that.

  4. Thanks for the video~ What soil is it in? and how do you know its a fungal infection and what do you use to treat it?

  5. There is need for this type of discussion on the mid levels of progression in the design process.
    Very informative. Thank you.

  6. Not understanding why the needles can’t land in the soil? Why can’t they just stay in the soil and decompose. Thanks, great video and informative.

  7. Excellent work Eric, that work on the crown sets the future as do the lower sections. Love this powerful pine

  8. Good luck to you and Jonas at the Pacific Bonsai Expo Nov 11-13. Looks like a great time coming up
