Eighteen Year Larch Progression

This tree was collected ca. 1995 by John Biel in preparation for the IBC ’97 convention in Toronto. Dozens of cedars and larches were collected to be used as workshop material for that event, and afterwards they were dispersed around North America with their new owners. If you’ve seen or heard of a thuja or larix in the USA that was “collected in Canada some time ago”, there is a fair chance that it was collected by Reiner Goebel or John Biel in the early ’90s in preparation for the convention. John and Reiner are two of the old guard of the Toronto bonsai scene.
Marc Noelanders styled this larch during a workshop at IBC ’97 and the new owner took it home. Unfortunately the owner passed away a year later and Reiner Goebel inherited the tree.
Here is the oldest picture I have of the tree in 1998.
The tree developed quickly in Reiner’s hands – here it is in 2004:
In 2006 it was potted into an outstanding Horst Heinzlreiter pot. At this point the tree was near its prime, with dense ramification.
Reiner is doing well, but as of this year is completely retired from bonsai. I bought this tree from him in 2015 and it was in a state of decline. It had not been pruned for a few years and most of the interior growth was dead. The tree was also quite weak – I don’t think it had been repotted since the previous image in 2006 (9 years prior).
The best features of this tree are the stunning old bark and the exceptional nebari (collected larches with good nebari are very rare). To highlight the elegant trunk and delicate bark, I removed the majority of the old low branches which had gotten too thick. This was a difficult decision as the branches had incredible character and old bark all the way out to the secondary branches. However, major changes were necessary in order to come up with a design that brings out the key features of the tree and is sustainable for many years into the future.
A few weeks ago I sat down with this tree and did some rough wiring. This is the best solution I could come up with. I’m pretty sure it isn’t better than the original design, but the important thing is this tree can be maintained in this image for a long time. I would really like to add a secondary trunk on the left side to make it a twin trunk, however it will be difficult to find a small larch which has comparable bark characteristics. Next year it will be planted either in a nanban-style container or on a flat stone.

Bending a Heavy Jin and Initial Styling of a Cascade Thuja
I collected this cedar in 2013 and only this year decided to style it as a full cascade. The big character jin jutting towards the lower left is amazing, but presents a practical challenge for getting the tree into a classic cascade pot. Instead of removing it, I thought it would be interesting to try to bend it flush to the trunk. In addition to solving the pot problem, it would also add some thickness to the base of the trunk, which has some distracting reverse taper.

Some of the jin had to be shortened so it could clear the soil surface when bent in. I hate removing ancient deadwood from collected trees, but sometimes it is necessary to realize the design.

The elbow of the jin was notched and some wood removed from the back. It was also wrapped in a wet rag several days before the operation.

Strategic parts of the jin were protected with aluminum foil then steamed with a torch to facilitate the bending. Two clamps were used to crank the jin in.

We were amazed that the jin did not show signs of cracking or tearing. When flush with the trunk, it was secured with two stainless steel screws.

After setting the basic structure. The two unnecessary branches will be kept for a year or two until the main foliage mass gains more vigour. Hopefully this will help minimize dieback of the two live veins, both of which are visible from the front.
Larches…

When you have a lot of larches spring can be somewhat of a disaster. Pruning, wiring, unwiring, and collecting more larches (glutton for punishment) all tend to fall within a fairly short window.
That being said, here are some larches at various stages of development that I have been working on over the past few weeks of this very strange spring (weather-wise).

This sinuous larch was collected in 2014 and styled a couple of weeks ago. A massive root was further reduced and it was planted in its first bonsai pot. Collected larches usually come with one or more massive root(s) which fortunately can be reduced over successive transplants. This will need one more big root operation in a couple of years.

This big larch was collected in 2014 and transplanted this year. It also had a massive root cut back closer to the trunk. It has a wild character and will take some pondering to find the best front and planting angle.

This stout little shohin was divided from the root system of the previous big larch. After a year or two for root development, it will be planted at the correct angle and will be pretty easy to make into a nice little tree. Without the old bark, this would not be worth much, but it is old and therefore has some good potential.

This chuhin-sized larch was styled for the first time last spring and is developing quickly. This year the wire was checked and the branches were trimmed with the aim of further developing the ramification. Can you see the single cone on this tree?

The one cone this tree produced last year happened to be in an ideal position and managed to hang on over the winter. The cone is about 1 cm tall.

This tiny larch (collected 2013) is notoriously difficult to photograph. Besides pruning, this tree has never been styled. Its development has been set back due to falling off the bench twice (once my fault, the second because of raccoons ). The bark, taper, and trunk movement are ideal. Next spring it will likely be wired. This year I just transferred it into a Nick Lenz pot.

This tree has taught me that larch are not as easy to thread graft as I would have thought. Nick Lenz estimates a 33% success rate. I have a 0% success rate. This year I am trying bud grafting on some larches, and (fingers crossed) seem to be having some success. I will also give summer thread grafting a try.

This craggy tree was collected in 2012 and had major root operations in 2014 and again in 2016. Finally, it fits into a bonsai pot. Last year some rough structural work was done. This year will focus on pruning and developing branching so it can be styled next spring. One thing I’ve learned with collected trees is that not rushing them will often help you achieve your goals faster.
Professional Image of Thuja occidentalis
This twin trunk thuja has progressed well since it was collected in Spring 2013. It was styled in the summer for the first time. While the foliage is still quite immature and lacking density, I am happy with where the image is going and it is becoming hard to imagine this tree without the lovely pot by Erick Križovenský’.
It was shown for the first time last weekend at the Toronto Bonsai Society Fall Show and Sale. The entire show was photographed by one of our members Mike Pochwat, who is a professional photographer. When the full album is available, I will share the link here.
We are extremely fortunate to have such a talented photographer in our show, and that he was generous enough to take his time to photograph our trees. Meeting great people like this is just one of the many reasons why I always encourage bonsai enthusiasts to join a local club.
Happy autumn to everyone! A busy time of year for us cold-climate bonsai nuts.
Sandblasting Some Large Eastern White Cedars
Prior to last week I had only tried sandblasting on one small cedar. The results were excellent, but I was limited to using my friend’s small parts sandblasting cabinet which could only handle a shohin sized tree. Recently, however, a member of our club got a full sized sandblasting tank and offered to let me try it out on some larger trees. Often sandblasting is done in an enclosed tent or room, but we just did it out on his lawn.
This tree was collected in spring 2013. Last year I did a rough initial cleaning on it using hand tools, but with a craggy old thing like this, sandblasting is the most efficient way to clean away all the old dead bark while preserving the details of the deadwood. Many of the cracks and crevices are impossible to access with hand tools. Sandblasting should be a once-in-a-lifetime event for a tree. Once it is done, the deadwood can be maintained over the years with gentle brushing (water and toothbrush) and lime sulfur application (although this is often unnecessary on thuja as their deadwood will naturally bleach in the sun as long as it is clean).
We used aluminum oxide media at 50-90 psi.

The tree before sandblasting. The trunk was wet at this point as it had been raining, so it is much darker looking than it actually is.

Preparation is important. Covering the soil prevents it from getting blown away. Covering the foliage is absolutely necessary – it will die if it is hit by the media. We chose to cover the live vein with modelling clay as insurance, although this is not strictly necessary if you are careful -the bark is surprisingly resistant to sandblasting. I’ve seen pictures from Takeo Kawabe’s book (Kimura’s student) who seems to sandblast junipers with no live vein protection.

After about two hours of sandblasting. 90% of that time was spent drinking beer and waiting for the tank to re-pressurize. Sandblasting requires a high CFM compressor and the one we were using was unable to keep up for more than a minute or two.

The medium we used left a slight texture behind on the deadwood but it is all we had to work with. I am still very happy with the results. The live veins will be further defined over the coming years.

This heavy break will unfortunately be hidden in the back of the tree. It is gorgeous but there are always compromises with yamadori.

Another candidate for sandblasting. This tree was probably collected in the 80s and was once a bonsai, but had been growing as a garden shrub for 10-15 years. Most of the branches are unusable and it will be a challenge to bring this one back. I’ve been rehabilitating it for two years, but you can only expect so much backbudding from a thuja.

You can see where some of the bark was blasted away, but nothing too major. I will likely polish the bark on this one anyway.

Original front of the tree 20 or so years ago. It is likely to become the new back as the deadwood is quite flat and the inverse taper more pronounced.

This tree was also sandblasted then a basic structure was set. Sorry, no before picture. It was collected in the 90s by a senior club member and is also quite overgrown, but not as bad as the previous one. It could be presentable in two years.

It is looking very sparse right now due to the removal of old foliage and unnecessary branches, but hopefully it will fill in before the end of this growing season. Its current sparseness gives an opportunity to see the strange relationship between the two trunks. As the foliage fills in, the pads and the spaces between them will become more well defined.

This tree is big, about 65 cm tall from the lip of the pot, and weighs about 75 lbs. The two top jins are of equal height – a problem which I will address the next time I work on the tree.

This is a photoshop adjusted picture showing how I would like to reduce the top jin on the right, and bend the jin on the left so that it better matches the overall movement of the tree.
Larch Thread Grafting Woes
Most of the old crusty larches I collect need grafting. It seems the older they are, the farther the living foliage is from the interesting part of the trunk. Three thread grafts were started on this larch in spring 2014 and all three of them failed this summer (despite not yet being separated from the donor branch).

Three dead grafts. The middle one was the most important as that was to become the new leader of the tree. The one above that… well it was too high i.e. a mistake.
I’m not sure why they failed, but I think it might have had something to do with long period of time elapsed. Ideally, once started, a thread graft will grow rapidly and then take within a few months. Unfortunately, these grafts hardly elongated last year therefore they had no change of reaching the thickness required for fusion until they really started to take off this year. But in July of this year when they should have been fusing, they were instead girdled and died. This is purely anecdotal, but I believe that the callus that formed around the edges of the drilled hole was somehow too hardened-off or otherwise too old to readily form a graft union with the threaded branches by the time they were thick enough to do so. Or maybe the drilled hole didn’t form a callus at all.
Anyway, they failed and I needed to re-graft. Late summer is not a good time for thread grafting larch, so I tried a traditional approach graft instead.

I’m not sure what these nails are really designed for, but in Japan they are commonly used for grafting. With this graft they are not going through the branch, but are just adjacent to it. With thicker branches it is OK to hammer them right through the branch. They do an outstanding job of creating a very snug graft junction.
First Styling of Small Thuja
This is one of my smallest eastern white cedars, collected in the spring of 2012. It took longer than it should have to reach peak health following collection because quite a bit of mucky field soil remained in the root ball until spring 2014 when it was completely bare rooted. This year it was healthy enough for a rough initial styling. Next year it will be planted in a new pot at the correct angle and the deadwood will be cleaned. It could be show ready by fall 2016.
Twisty Twin Trunk Thuja in Erik Križovenský Pot
This serpentine tree was collected in the spring of 2013. I’ve always admired Erik Križovenský’s bonsai containers and thought this tree would be a great candidate for his unique style so, in 2014, I commissioned him to make one for this tree. Many people have tried to imitate Erik’s style of containers, but I’ve never seen anyone get it quite right. Furthermore, Erik has an incredible eye and designs containers to specifically match the style of each tree.
Erik is based in Slovakia and his work can be seen on his website Atelier Bonsai Element.
I hope you enjoy the following photo essay.

This tree recovered faster than most, so received a rough initial styling in June 2014. This was the picture I sent to Erik for his design input.
Thuja occidentalis cleanup
This tree was looking pretty good last August but I am hoping it will be looking even better by the end of this year. But before that it will have to look like crap.
It was finally repotted this spring into its first bonsai pot, some five years after collection. I am not completely happy with the planting angle nor the positioning in the pot, but that was the best I could do given the placement of the roots. The quality of the pot is not ideal either, but a comparable high quality container would be very, very expensive. If I could even find one. I am thinking about ideas for a custom made container in the future.
Much of the wire from last year was already biting in severely so the tree was completely de-wired. When I remove wire I always try to unwrap it instead of cutting it off. As far as I can see, there are three benefits to unwrapping the wire instead of cutting it off:
- it is much faster to unwrap it than cut it off bit by bit
- you are less likely to miss little loops of wire which could girdle branches in the future
- it is impossible to cut off wire that is biting into a branch without severely damaging that branch. You have to unwrap it.
The exception is very thick work-hardened copper wire which can be very difficult to unwrap without twisting the branches. I usually cut that off if possible.
The tree was also thinned quite drastically. This will simplify the upcoming wiring process and also improve the branch structure. And for the first time, the deadwood was properly cleaned and some old dead stumps were refined. It was also treated with a 50% dilution of lime sulfur.
It is now resting for a couple of weeks then it will be wired.
Preparing Displays for Toronto Bonsai Society Show and Sale
Here is one display I will have at the Toronto Bonsai Society Show and Sale this weekend. I hope to see you there!
Larch Madness
If you follow the traditional guidelines, the best time to wire and repot Larix laricina is when the spring buds are just starting to open. This is usually the most practical time to unwire larches too, because around here it is the only time they are without needles and not frozen in the ground. This “spring buds just starting to open” window can be very short – often just two weeks in mid to late April. Needless to say, if you have a good number of larches like I do, spring gets pretty busy. Add to that repotting a couple dozen more trees, building a new bench set up in my yard, and a couple of collecting trips, and you have an insanely busy last few weeks.
Here is one larch that I recently worked on. This tree changed hands a couple times in the last few years, and I snatched it up almost exactly one year ago as soon as I had the opportunity. I was collected about 20 years ago yet has spent most of that time in bonsai limbo, without a coherent design. Most of the finer tertiary branches used to create this structure were grown last year.The tree was also gently repotted into a simple Yamaaki container that suits the semi-cascade style pretty well.
After a few more years of ramification development, this will be a killer chuhin sized larch, and I am proud to be its new caretaker.
Thuja occidentalis Foliage Shedding
This is peak season for eastern white cedar foliage shedding. While not at all a health concern, it is somewhat unsightly and can leave your tree looking quite sparse.
To reduce autumn foliage shedding, I’ve been following the advice of Reiner Goebel and making sure I prune my cedars some time around mid-August. This year the results are really showing. Bear in mind that if a tree is early in it’s development or recently collected, it is often better to avoid pruning and just let it shed.
Thuja occidentalis progression
This is the first large Eastern White Cedar I collected. After four years of growing, the foliage mass was finally ready for some real work and this year it has gotten a lot of attention. In July it was thinned and roughly wired, and today it received its second and final thinning for the year.
I think this tree is actually two separate trees that have been growing together for a long time. The second trunk on the right is growing towards the back, and I’ve always toyed with the idea of removing it since it seems out of place. David Easterbrook and Marco Invernizzi both advised me not to remove it, and now I am starting to understand why. That secondary trunk provides much of the depth of the tree and without it I would be left with something very two-dimensional.
It will be difficult to find a traditional bonsai container that works for this tree. I’ve got some ideas for the future planting, but it will not be easy to pull off. The final planting will determine which of the large jins I end up keeping, if any. If I can sort it out next spring, this tree might be ready to be shown in Fall 2015.

As collected Fall 2010. Note the fist-sized rock lodged in the base of the trunk which had to be cut out with a die grinder.

Summer 2012, completely barerooted to remove the toxic muck and repotted into a much smaller grow box.

Summer 2013. Some major pruning and coarse wiring was done this year to open up the foliage and set the basic structure of the secondary branches.

Today after another round of thinning and minor adjustments. There is still a fair amount of floppy foliage but that is gradually being replaced with tighter growth or removed entirely.
Thuja occidentalis Initial Cleaning
This large Thuja was collected in Spring 2013 and this year has been growing well enough that I have started some basic work. In the first year of collection, I try to do absolutely nothing to a tree – not even move it around the yard. Cleaning work like this invariably involves bumps and vibrations, so I don’t do it until the tree is obviously strong and established in the grow box – typically the second year.
This is not a thorough cleaning – just the removal of bark that come off easily, getting piles of detritus out of cracks and crevices, and cleaning the deadwood with water and a toothbrush to get rid of algae. After this it is easier to study the tree and identify the path of the live veins. As the live veins swell up over the next few years, they will be defined further.
The thin dead bark that is really stubbornly adhered to the deadwood will gradually be picked at over the next few years. Removing it right now would require aggressive scraping or rotary brushes that would ruin the natural texture of the ancient wood. I’m estimating this tree won’t be show ready for around ten years, so there is no point in rushing things. Cycles of wet-dry-freeze-thaw will aid the gentle removal of the bark.
Next spring it will be bare rooted and repotted into a much smaller pot or box. Like most collected Thuja, designing this tree will be a serious challenge. Semi cascade seems like the obvious direction but close examination reveals that there is no easy solution.
Small Thuja Wired
Collected Spring 2011, about 30 cm to the tip of the dead spire. The deadwood of this tree was sandblasted last year which helped preserve the lovely little jins. The pot is by Shibakatsu.
Stolen American Larch Bonsai
This old American larch (tamarack) bonsai, along with two others, was stolen from a private collection in Toronto on June 23rd, 2014.
If you have seen this distinct bonsai, please call your local police department and/or contact the owner Elisabeth Leslie ewleslie[at]icloud.com
The bonsai community is tight not only in Toronto but worldwide. Hopefully we can use this to our advantage to help get this lovely tree back to the owner.
The Feels of Bonsai
According to Ryan Neil (see this video starting around 26 minutes, courtesy of the most excellent and prolific Bonsai Eejit), the overall feeling of a bonsai is determined by the combined directions of the trunk, main branch, and apex.
Three common scenarios are:
- Trunk, main branch, and apex all move in the same direction. This creates a calm, feminine bonsai.
- Trunk goes one way, but the apex and main branch go in the opposite direction. This creates tension.
- Trunk and apex the same way, but the main branch goes in the opposite direction. This creates dynamism and is rarely seen in Japanese bonsai.
Of course there are other scenarios such as the trunk and main branch going the same way while the apex goes off in the opposite direction. My guess would be that this creates imbalance thus it is difficult to design an attractive bonsai with this layout.
Ryan’s comments really stuck with me when I first saw this video. This is a simplified but useful approach to bonsai design. Of course, there are exceptions to the above scenarios just as there are exceptions to everything in bonsai.
When I was doing the initial wiring on this Thuja this weekend, I was aiming to create scenario #2 – Tension. Two trunks which strongly move to the left and apices/branches which strongly move to the right. This made a fun and compact design.
As a side note, my initial plan for this tree was to have everything moving to the left… trunks, branches, apices. It seemed like the most logical design. However, doing this would cover up the best feature of this tree – the two “kinks” in the trunks that boast some very nice deadwood. The current design makes it possible to emphasize those kinks and, importantly, makes a more compact tree.
Devilishly Sinuous Twin-Trunk Thuja
Trunk lines like this are what keep me trekking into the wild each year to scour for nature’s freaks. This tree was collected Spring 2013 and is gaining strength quickly. I am excited to do the initial work this summer.
New Pot for Potentilla fruiticosa
Quite a flamboyant choice. Perhaps too flamboyant? Well, it technically is a flowering tree… although it certainly doesn’t carry that presence.
Regardless, I find it a fun change.
Perlite is good (but that doesn’t make it pretty).
I’ll keep this brief because soil discussions are not exactly exciting.
This is the first tree I’ve repotted since I started putting all my collected trees in 100% perlite two years ago. The root growth has been excellent and I was glad to see that there has been no noticeable decomposition of the perlite after two winters.
There are probably a million other substrates that larches grow equally well in, but you would be hard pressed to find one that is as inexpensive and lightweight as perlite.
So perlite is good. Not exactly revolutionary.
/end of soil discussion.
The red stuff you are seeing all over my trees is coloured mulch. I got it for really cheap last autumn but now the damned stuff is everywhere!
A Few Images from the Toronto Bonsai Society Show
Despite is being a less-than-stellar year for fall colour, TBS still put on a good show. Unfortunately I didn’t bring the correct lens for the job so I wasn’t able to get far enough back to get most trees in frame. So here is a small sample of some trees that were on display at TBS.
I’m very proud of myself that I didn’t buy anything in the sales area, despite there being some nice trees that got snatched up pretty quickly.
… well I did buy 10 bags of lava rock, but soil doesn’t count 🙂

Very nice chuhin Japanese maple, trained by one of TBS’s senior members for many years from either a cutting or an air layer.

Great pot by (I think) Horst Heinzelreiter. A creative pairing with this tree that I think works extremely well with the fall image.
Grafting Hinoki on Thuja: Round 3
In Spring 2012, I tried bud grafting hinoki foliage on a scraggly collected Thuja, which failed. Later that year, I tried approach grafting hinoki foliage onto the same plant. Over one year later, the results are still unclear. The approach graft is alive and well, but it has not clearly fused with the Thuja tissue. I have a feeling the wounds on scion/stock both just healed over instead of grafting with one another. At this point I would say the approach graft was not successful.
Nevertheless, I left the approach graft in place and moved on with my third attempt of grafting this plant with a third type of graft: the One-Point aka Single-Point Graft.
One-point grafts are very similar to thread grafts, except defoliation is not required. This makes this type of graft a very useful tool for conifers. Many years ago, I successfully one-point grafted my Canadian Hemlock (Tsuga canadensis) after learning about this type of graft from Nick Lenz’s Bonsai from the Wild 2nd Ed. In fact, Nick hints at one-point grafts as being appropriate for Hinoki-Thuja operations, but first describes them in his larch chapter:
A variant of [thread grafting] is the one point graft. Instead of passing a bald branch through a hole in the trunk, you fold over a branch and squeeze it into the hole. Before insertion, you scrape the outer edge of the fold with a thumb nail to remove the cambium. When jammed into the hole, the cambium layers of the drill-out and of the scraping will touch and merge quickly. This approach has several advantages. You can perform it at any time during the growing season as the branch does not need to be bald. This is especially useful in species that grow out but once in a season, such as pines. It also takes less time to complete. You do not have to drill all the way through the trunk, but only a centimeter or less.
The disadvantage to this approach is not great. The branch may be fatally injured when folded over. If this happens and the new graft begins to dry and brown up, you can readily pull it out and try again with a smaller branch. Despite the tendency of a branch to break (crack) when doubled over, you can always find one that will tolerate the procedure. Success is more likely on hot, dry days when water is withdrawn from the wood. -Bonsai from the Wild 2nd Ed., p. 33
A few weeks ago in mid August I looked disgustingly at my still-ungrafted Thuja and grabbed my drill. Three one-point grafts were initiated and today they all still seem to be alive. Basically what I have now are three thread grafts in my Thuja, and hopefully now it is just a waiting game.

A one-point graft that seems to have survived the initial folding-and-cramming. The scion for this graft was growing off the scion used for last year’s approach graft.

Another one closer to the base of the trunk. All of the one points were slathered with some Japanese wound sealant which is pretty much white glue.

I’m not sure if this tree is even worth all the trouble. Sure, it will be nice if I can make it a bonsai, but this grafting project now seems more about me proving to myself that it can actually be done.
A Big Thuja That Was Collected This Spring
This large Thuja occidentalis was captured in April of this year. All of the pictures except the last one were taken in April soon after collection, when the tree was still in it’s dull winter colour.
The trunk is huge with some dramatic movement. The deadwood also tells some fascinating stories, particularly the massive break in the 8″ diameter middle section. One has to wonder how damage like this could be done without completely uprooting the tree.
This tree certainly doesn’t present any easy design solutions, so it will be a challenge. Currently these are the best pictures I have of the tree as it is tucked away in the rehab area.

I’ve been planting all of my larger collected trees in pure screened perlite for the last couple of years.

Before root washing and potting up, giving a glimpse into the base of the tree. This is a good example of the impenetrable root mass that Thujas are often collected with. Very little of it is actually live root. Hosing out as much muck as possible greatly simplifies watering the containerized tree.
Some details:
