The evolution of a large Ficus microcarpa – Part Two

The first 5 years of progress with a Ficus microcarpa, Chinese Banyan, was outlined in a previous blog see http://www.bonsaihunk.us/public_html/?s=part+l

This  is an update on how this fig has progresse as of April, 2015. It still has some years of refinement to undergo before it can claim its position as a mature bonsai.

Two procedures were accomplished today that are helping bring this bonsai in training a step closer to its end point. One, is to reveal the thickening produced by the second set of fusion grafts of rooted branches that were started 5-6 months ago.

The second procedure was the approach graft  on the right . Previously 3 approach grafts were tried and all failed for various reasons. A fourth approach graft  was done today to once again try to get a branch established in this position. Since it it is the first branch and lowest branch on the right side of the tree it is crucial to have this set in proper position of good size and of the right shape as it will be key to setting the design of the rest of the bonsai tree.

As of 2015 the process is now 5 years along since started by Jack Pollock and the tree is moving along amazingly well. I am guessing that another 3-5 years will pass by before the tree is an attractive bonsai. In the meanwhile the tree has provided me a lot of reason to continue to learn and grow in  the wonders of the bonsai world.

The evolution of a large Ficus microcarpa – Part One

This Ficus microcarpa, Chinese Banyan, was a gift from bonsai friend, bonsai grower and dealer Bonsai Jack of Florida –  http://www.bonsaijack.com

Jack sent me this tree after initially styling it in 2010. In the first few shots you can see how the top of the tree was totally removed and all the China grafted branches were removed leaving the wild form of Ficus microcarpa to sprout back and provide the new branches for the future structure of the tree.

The first set of fusions to bulk up the apex

The apex was so thin and not believable that I brought up two or three additional branches from the trunk and used electrical ties to force fusion and thickening of the apex. This worked very well and by October of 2014 I felt that even more thickening would be needed

The apex fusions did very well and were completely fused but the apex was still too thin to be believable as a good transition of the topped trunk so about 6 rooted cuttings previously taken of this same tree were attached with electrical ties to the apex and their roots inserted into a plastic baggie of soil also attached to the top of the trunk.

The baggie contains soil to allow the roots of the rooted cuttings to survive and fuse with the apex

In the process of doing this second fusion set to the apex my assistant accidentally bumped the previously grafted right main branch and it was broken off.

To replace this another previously rooted cutting was inserted into a hole drilled into the trunk. The root was draped out of the drill hole and into its own pot of soil and covered with sphagnum moss.

The new right sided branch graft soon failed and I made a third attemp to get a right sided branch by doing an approach graft from the thin back branch brought forward and inserted into a fresh groove in the trunk. The graft was secured with staples as you can see below.

This is the 3rd attempt to get a right sided branch – approach graft from the back

Time will tell how this all will turn out. So far I am quite happy with about 2.5 years of work and progress on this huge fig. Bonsai is a never ending process of refinement and change necessitated by how the plant grows.
