Both my bonsai and personal life have been busy of late. I am fortunate that this year I have been invited to demonstrate and run workshops across Australia for local club, groups and the AABC National Convention. On top of this travel I just begun winter styling of clients trees. It looks like I will have a fairly full book of client trees, workshops and demonstrations that combined with a young child, a house half way through renovations and a full-time job doesn’t leave a lot of time to work my own collections.
Today’s post is actually about a tree I worked on a year ago whilst in japan.
It was a small shimpaku juniper that Oyakata asked me to wire and style prior to taking it to auction the following day to be sold.
I initially wanted to tilt the tree to the right so that the first bend would come in contact with the soil giving the appearance of a much larger trunk but Oyakata didn’t want to re-pot as the auction was so close and as a result we utilised the existing angle and front.
It turned out to be a fairly straight forward re-style and Oyakata told me it sold well at the auction.
Looking back on trees like this it really gives me the incentive to start growing my own material to this standard. I now have a backyard big enough to experiment with a whole lot more stock so I am looking forward to starting this process off this year. Who knows, in ten years time I might have a whole lot of these ready for display………..
As you may or may not be aware, I have recently undergone surgery on my right wrist. Being right-handed, this has put a fair dent in my bonsai plans of late.
A few nights ago after work I decided to do something about it and tried wiring up a small juniper.
I have been working on this tree for a few years now, slowly chasing the foliage in closer to the trunk and replacing leggy growth with tighter growth. I decided that it was about due for its first styling so that I could create the bones to grow and fill in the foliage upon.
Considering that my right arm was in a cast I think the wiring went ok. It’s not show ready but it never was going to be. It has a few more years before it is going to be anywhere near presentable.
I really wanted to get some fine sand paper into the bark to reveal the orange / red texture below the outer layers but the cast proved too clumsy. Something to look forward to once the pins from the wrist are removed after the next operation.
I find that when wiring junipers and particularly shimpaku, that preparation is key to a good result. Pruning unwanted growth and thinning what remains so that you end up with an evenly dense canopy not only makes the end result look better but it also makes for more balanced growth and an easier job while wiring.
All in all I am pretty happy with the results considering that most of the wiring was done one-handed. I guess it just goes to show that interesting trunk movement is half the battle. That being said, the tree is only just beginning its journey as bonsai and should see many future wirings to come.
Following on from yesterdays post I thought it would be good to include some examples of approach grafts that were at Taisho en while I was studying. The two examples below are using approach grafting for two different reasons. The first is grafting roots onto an upper section of a trunk to shorten a bonsai. The other is using the technique to both replace foliage and graft on new roots.
taxus tsuga above was an interesting bonsai with an un-interesting lower trunk. The image of the bonsai could be greatly improved by shortening the trunk and hence roots were approach grafted onto the trunk.
The below juniper was undergoing a major change too. It was a tosho or japanese needle juniper (Juniperus rigida). It was very large stock extending about 2-2.5 meters in length. It had some great movement and excellent jin/shari. The future for this tree was to break it up into sections. By grafting new roots and new foliage along the live vein at key points the large piece of stock would be able to be broken down into 3 or 4 bonsai, all with nice movement and good foliage. Shimpaku juniper was grafted onto the tree instead of more tosho as it is a more popular species and therefore easier to sell once the separation is complete.
Hopefully from these two posts you can see the possibilities that this technique can provide. The ability to manipulate your stock and bonsai is a powerful tool in the bonsai artists arsenal. Shortening trunks, adding branches and changing foliage types can be controversial in some bonsai circles but I think that when push comes to shove the results speak for themselves.
I have been quite lucky that I have been able to visit a number of Japanese nurseries (SEE HERE). I love seeing the high quality trees and amazing level of finish and polish that these trees posses, but what I have also found very interesting during these visits is looking into the back of house areas where bonsai are in various stages of transformation.
Air layers, grafts and other techniques are all on display out the back of most nurseries. It not only gives you a look into these techniques but also gives you some ideas on what sort of material to apply these techniques to.
One such technique is approach grafting.
While I was studying at Taisho-en I was able to see this technique used to improve a range of stock. Shimpaku were given smaller foliage. Needle junipers were given shimpauk foliage. Roots were moved closer to the foliage to shorten trunks. It was obvious that after only a short stroll through their back of house that this was a valuable technique.
The technique itself, whether you are grafting on new roots or new foliage, is rather simple.
- Find a scion whip of the same species around 1-2 pencils thick and slice a sliver of bark off opposite sides at the point you want the whip to be grafted.
- Cut a channel in the trunk the same depth as the whip is thick.
- Widen this channel with a sharp knife to ensure clean cuts. The width of the channel should make a snug fit for the cut down section of scion.
- insert the scion into the stock trunks channel. Ensure that the cambium layers meet up accurately along the top edge of the channel cut.
- Fix the scion into the channel so it will not move or become miss-aligned. You can tie it with grafting tape or use a nail or two, screw etc.
- Cover it all in some type of sealant and wait for it to take.
The scion whip can be from several sources. It could be a long branch doubled back on itself and grafted into the trunk, or could be a small whip that is growing in its own pot. If your scion is of the second type you may need to wrap the root ball in hessian or towel if the root ball ends up in a strange position after being grafted.
How long does the graft take to be successful? That is a difficult question. It is species dependent, growth dependent and also depends on how well you aligned the cambium layers in the first place. Although you can have success with poorly aligned cambium layers in this technique due to the face that both scion and stock support themselves before the graft takes, it is much faster to align the cambium correctly from the get go. I would say that most approach grafts would need one to two years to take. After that you could begin to reduce the original foliage over time and slowly let the new grafted foliage take over.
All in all it is a very useful technique that can be use to get you new roots, new foliage and generally improve difficult stock.
In the next day or so I will be posting a few examples to further illustrate the technique.
To see some real life examples have a look at “Approach grafting 2”.
The tree below is one I worked on a couple of years ago. It is a large Shimpaku Juniper that had some great deadwood. When I was working on it, it was in the process of having some new roots grafted onto it. Because of this the styling was kept to just main branches, leaving the tips somewhat free so as not to stress the tree too much.
On my latest trip to Japan I re-visited Taisho-en and was reaquainted with this tree. The grafts had been a success and the tree had found a new home in a new bonsai pot.
It’s always nice to see trees you have worked on after some time apart. I get a similar feeling to that of seeing an old friend. When I saw this tree in the nursery I took my time looking over it and revisiting the familiar curves and lines of the trunk and branches.
I wonder if we will cross paths again.
The tree in this post was another i worked on while in Japan. It arrived at the nursery one day and was in need of a re-think and re-style.
The major change was to stand it up.
I first wired the tree, keeping the small second trunk and then re-potted it into its new upright position.
As the tree had its angle changed so dramatically it needed time to re-establish a new rootball that could support it in its new position. In the mean time a bamboo prop was used to take the weight of the tree while the rootball became stable enough to support itself.
Unfortunately some of the lower shari had been buried in the previous potting angle and as a result had rotted. I feel that the base would have appeared much more impressive had it still had deadwood at its base.
It was a nice tree to work on, but at the time i guess it got lost amongst all the other high quality trees in the nursery.
This was by no means a top tree but looking back at it now I would kill to work on material such as this in Australia.
I guess I will have to sharpen the shovel and keep an eye open for urban junipers in friends gardens.
I like growing and working on shohin sized bonsai. This Shimpaku was another that I was lucky enough to style while at Taisho-en, Japan.
It had all the makings of a good bonsai, but had become overgrown and needed to be styled.
The trunk line had an interesting twist and the shari and live vein had started to contrast with one another nicely.
This work was really just a wiring exercise. I was able to position most of the foliage into good positions but it really needed a year or twos growth to fill out some of the weaker branches. The foliage was positioned in a way to allow the viewer to see the nice twists in the trunk and shari.
All in all it is a very nice tree that can only improve as it ages. This was definitely a tree I wished I could have put in my suitcase before I left.
The following tree was a large Shimpaku (Juniperus chinensis) I worked on towards the end of my first stay at Taisho-en, Japan.
It is a tanuki (or phoenix graft) which had a couple of issues.
The first problem was that the grafted foliage was of a very large and coarse variety which at the time of styling was not particularly popular with buyers in Japan. They were more interested in the fine dense foliage of the itoigawa shimpaku from the Niagata region and similar fine shimpaku varieties.
The other problem was that the live veins were not entirely convincing in how they were attached to the deadwood.
Having said that I still feel that the tree ended up an impressive bonsai and I am proud that I was allowed to have an imput into the tree future.
This is the first post i have made on this new blog. Hopefully these posts will be fairly regular and will record whats happening in my garden and any interesting things i come across. I will also try to include a few bits and pieces from my studies at Taisho-en in Japan.
As a start i will kick things off with this small shimpaku i styled on my last visit to Taisho-en.
