Structural Work on Bonsai

June 12, 2022June 12, 2022Bonsaiplace 3 Comments

Winter provides good opportunities to do structural work on deciduous Bonsai trees. Sap flow is low, no leaves means you can see what you are doing and wiring can set branches before Spring growth starts.

This Cherry tree was collected about a year ago and was just a trunk, in this case a triple trunk at collection. The original tree was about four metres high and in a forrest which means it was quite lanky with no branches towards the bottom. One year later and it has put on a lot of new growth and the fine root development is spectacular.

It has three quite large scars on the end of each trunk and then also a very big one on a chopped root. The middle trunk is dead and has been at collection already. This trunk was rotten and easy to just break to shorten it. As the root scar was going to be large, it was decided to have that at the back.

Once the front was established, extra branches were removed and a few at the top were shortened. All branches crossing the main trunks or too low down on the trunks were removed. The same happened where two new branches grew from the same place or they were just too close to each other. A few branches were in a 50/50 situation and these were left for now to be decided on later. Always start by removing large parts first. In this case it was mainly the root which was removed with a reciprocal saw and then the larger bit on the die grinder was used to set the first grooves by also creating some taper. This was then followed up by ever decreasing sizes of bits and once everything was carved, a wire brush and then a nylon brush was used to clean and polish the carvings. By polish I mean brushing vigorously to remove fine threads and fibres left over from the carving. I usually use a blow torch to help with this action, but in this case it was decided to not use the torch.

Once this phase was completed, the carving started. This was a three hour operation using different sized carving bits with both a Dremel 4000 as well as a trusty old die grinder.

The last step was now to apply wire and set the branches. A few more branches were removed and it was also decided to plant the tree on an angle leaning forward a bit more once Spring sets in. This will be a naturalistic looking tree with a large and rounded top with the shorter trunk carrying the lower branches on the left hand side. There are still a couple of branches that will probably be removed, but that will come later depending on further development. An example of this are the two branches that looks as if they are coming of the front of the main trunk about a third from the top.

Now it will rest and as soon as the buds swell a fertilisation program will start and a sharp eye be kept on the wire as it will cut in quickly as the tree grows. Watch this space for updates.

Update on Gardenia Bonsai

June 5, 2022June 5, 2022Bonsaiplace 3 Comments

On 28 February 2021, I posted a blog article named “Off the back of a truck”. https://bonsaiplace.net/2021/02/28/off-the-back-of-a-truck/

In that article I speculated about the specie of plant and my guess was correct as it is indeed a Gardenia. It flowered not too long ago, only one flower, but between that and the glassy leaves, the identification is now locked in.

The photos below are of the plant when I found it on the back of a truck on its way to be dumped as well as a photo when it was potted up on that day.

This is now just more than fifteen months later and the photo below shows the growth since the first planting and as mentioned, there was also a flower during the last summer.

The tree has been fertilised regularly, mainly with a liquid seaweed type of fertiliser, but other than that, mainly left alone with a regular watering regime. It is now time to do a bit of thinning of the branches, light wiring where necessary and inspection and a bit of work on the pruning cuts.

There are two things to consider now. The one is to change the angle as shown in the picture below and to even tilt it even more in the direction shown.

The second one is to remove the thinner, lower branch on the right. That might even be done sooner rather than later.

In summary. This is the start and where we are today.

Now it goes back to the bench and another year of watering, fertiliser and providing optimum growing conditions for this tree to thrive.

Texture in Bonsai

May 29, 2022Bonsaiplace 1 Comment

The Merriam-Webster dictionary defines Texture as the visual or tactile surface characteristics and appearance of something. Bonsai is a very visual art form and therefore texture does play a vital part, not just in the individual parts of the Bonsai picture, but the whole picture as a whole. There are already so many things that play a role in the overall aesthetic display and look of a Bonsai tree, that to bring out one specific aspect, might be one step too far for some. However, we will break it down in the different parts and as you develop on your Bonsai journey, more of these features can be combined. Each individual aspect will make reference to its place as part of the larger whole.

Pots or containers

These come in various sizes, colours, shapes and also textures. There are some generalisations around like conifers do not necessarily go into glazed pots, but only unglazed pots, and then also that the pot colour should either match the flower colour or be of a contrasting colour. Let’s for the sake of this article, focus on texture. Needless to say is that a very refined tree, with a more feminine appearance and feel, will look odd in a rustic, unglazed pot. There is also a saying that the pot is like the frame of the picture and should enhance the visual appearance of the tree. It is therefore logical to say that smooth pots, usually glazed, is better off with trees which have smooth bark or a smooth leaf surface. A very rustic old Pine tree will probably look better in a more rustic container that could even have the texture of a rock or similar to the craggy old bark. The word generalisation has already been used here and it is common place to bend and break “rules” if the appearance of the whole visual picture will be enhanced in so doing. In short, as the pot or container is such an important part of the final look, it will pay to think about texture as well in selecting the best pot for the tree. It is definitely more than just size, colour, shape, depth, glaze, texture matters.

Bark

From a visual perspective, and especially when the bark is well-developed and stretches down to the soil surface, it is one of the most striking aspects of a tree from a textural perspective. Bark comes in many forms, shapes, colours, sizes and thickness. The same can be said for texture. The two main characteristics will be either smooth or rough with anything in-between. Then there is also the fact that some trees will form bark plates and others could have flaky bark. All of this is determined by the species and is a natural characteristic that is genetically determined. All the Bonsai artist can really do here is to ensure that the bark is protected or removed if it needs to be. The latter refers to some Junipers where the flaky bark is removed to show the rich contrasting reddish live veins off against the stark white of deadwood. Bark is a sign of age and therefore a very important aspect of increasing the aged look of the tree.

Jin, Shari and Uro

This goes hand in hand with Bark and influences textural aesthetics of the tree. This also can be used to enhance aging characteristics due to the textural differences between these features and the rest of the trunk, stems or bark.

Foliage

When it comes to leaves or needles, the usual visual impacts are those of shape, colour and size. There are textural aspects when it comes to foliage that are important when it comes to overall appearance of the art work. Things like, softness, hardness, smoothness and then also in a lot of broadleaves, like Rhododendron and some Magnolia, the two leaf surfaces showing completely different textures on the two leaf sides. We do find some leaves with a smooth top (adaxial side) and the underside (abaxial side), could be hairy. In Bonsai, it is rare to see the lower side of leaves, but if there is a unique difference in texture, it might pay to find ways to show it off. That is where creativity can trump practicality or “rules”. We all know about the spectacular autumn colour changes we see in some deciduous trees, but it is good to note that when the colour changes happen, there is at times also a textural change at the same time.

Other aspects

Flowers: The more striking aspects of flowers and fruit would be the colour, size and shape. It is worth noting that flowers have different textures, not just the whole flower, but also parts of the flower can be different.

Soil or surface cover: This refers to the upper layer of the soil that is visible in the pot or container. Texture here is important as well. The soil particles itself can form a visual pleasing aestehtic, but it is more common to cover this with something like moss. Just within different moss varieties a whole lot of different textures can be found.

Stands: Bonsai are usually displayed on a stand and traditionally these are made from wood. In modern displays it is not uncommon to see different materials being used. This could be steel, composites and even glass.

It all comes down to the aesthetic and the visual impact that will enhance the tree and texture is a force to be reckoned with when these decisions are made.

From Garden Plant to Bonsai

February 26, 2022February 26, 2022Bonsaiplace 6 Comments

I am always on the lookout for new material and prefer to work with material that has accumulated some age and character through being garden plants or from nature during the first phase of their lives. Sometimes they come for free and sometimes you have to pay. These two Azalea plants were advertised for free and just needed to be dug out. That took two minutes as these are shallow rooted plants.

Freshly dug Azalea plants from a garden.

Freshly dug Azaleas and the first step is to remove all dead branches and then also to remove most of the garden soil. It is better to remove all old soil, but in some cases it is ok to leave some of the garden soil depending on the season. You do not always have a choice when the plants become available and then you have to make informed decisions about how far you can go, especially when it comes to root work.

These two were potted up and we also managed to get seven smaller plants off the larger clump. Needless to say, these two are clump style and will be grown and refined over the next few years as such.

Potted up and ready to start the Bonsai journey.

Aftercare is the most important aspect when it comes to doing work on plants out of the optimum season. Watering is a big part of this and after I have watered the plants in, I always water with a nutrient rich tonic and fertiliser and prefer liquid ones. My go to preference is Swift Grow due to the fact that it is organic, contains all needed nutrients and very important for me, the right probiotics to get the roots off to a great start.

Wound healing in Bonsai

February 6, 2022Bonsaiplace 2 Comments

It is necessary to have skills and knowledge about the treatment of wounds in Bonsai as pruning leads to the creation of wounds. Here we are not talking about the cutting of thin new or green growth, but more the structural pruning leaving larger wounds in more woody growth.

It is important that the tree is healthy before big cuts are made as it is stressful for the tree and critical that the conditions are maximal for optimal healing and growth. A free draining soil, good light, water and fertiliser are all requirements for good healing.

A cut from two angles showing some deadwood as well. All of that needs to be removed. This is also the opportunity to slant the cut so that it is less visible.

Both cuts on roots and cuts on branches and the trunk can be treated in the same way. What you need is:

A sharp cutter. I use a craft knife with replaceable blades. It needs to be very sharp and sterile.
Knob cutter or concave cutter. See tissue thickness requirements in the next paragraph.
Cut paste, either the putty type or the more liquid one.

If the tree has relatively thicker living tissue (cambium and outer layers), a concave cut needs to be made and if the tissue is very thin i.e. Azalea, then a convex cut can be made. Anything in between needs a flatter cut.

Start by using the cutters to either flatten or hollow the area of the cut wound. Use this opportunity to reduce the area by cutting at an angle or to the back of a branch.

Use a very sharp, sterile blade after most of the unnecessary material is removed.

It is important that the cut area is as smooth as possible. What is meant by this is that a ridge in the middle of a cut will cause the new tissue to bulge over that or even stop the formation of new tissue. The living tissue (cambium outer layer) must be intact and the best way to do this is to run a very sharp blade across it. This will allow intact cells to multiply better and faster to grow over the open wound. Also referred to as the cambium rolling over the wound. Once the wound is clean, relatively smooth and the cambium prepared, use cut paste to cover the wound, especially the cambium. Proper cut paste will keep the cambium moist and it also contains chemicals that will enhance the growth of new cells.

Cut paste applied and you can also see the more acutely angled cut compared to before.

Allowing branches to elongate freely in the vicinity of the wound will help to bring nutrients and hormones to that area for faster healing.

Healing cuts with cambium rolling over. The edges of this cambium can be cut again to stimulate further growth until the cut is completely covered. The wound will eventually be fully covered and will continue to recover if the early steps were done right.

The area could be cleaned again after a few months of healing. Remove the cut paste and study the progress. If it looks as if the cambium roll over came to a standstill, gently open the edge of the cambium up again, apply cut paste and repeat the wait and check again process.

Carving on Bonsai: Sculpture

August 8, 2021Bonsaiplace 2 Comments

A previous blog post addressed sculpture as an art form and how it relates to Bonsai (https://bonsaiplace.net/2021/03/28/bonsai-as-sculpture-an-art-form/). This blog post will take an more practical approach by making use of photos to describe the process.

Carving is usually done to create or enhance jin, uro (holes), shari (stripped bark) or getting rid of areas where large branches were removed. In this case a large branch, about one inch thickness, had to be removed and it was decided to leave a 15cm piece of it and sculpt a jin (deadwood) out of it.

I use a die grinder with a carving bit to remove material fast and to roughly shape the dead straight branch by making grooves in curves and alternating the depth of the grooves. Once this is done I burn the jin to get rid of wood fibres and then repeat the process with the trusted Dremel and a smaller carving bit.

As mentioned, burning the jin with a butane torch gets rid of the loose fibres, but it also helps to get rid of sharp edges and tool marks. After a heavy torching, the jin is brushed with a copper brush and then with a nylon brush. Sand paper can be used to smooth areas that needs it, but I find that the brushing works well on its own.

To preserve the newly carved jin, I wash the whole tree off and then let it dry and rest for a few days. Lime sulphur or a wood hardener can then be applied. For a darker finish, mix some ash (burnt paper) in water and paint on. Some of the grooves can also be painted by making use of black ink. All fluids should be diluted. Lime sulphur is usually diluted with water 50/50%.

Safety aspects:

Wear safety glasses during the carving phase.
Use gloves when using the power tools.
When using the torch, protect the rest of the tree from the flame by using aluminium foil or a wet cloth around foliage and nearby parts.

Pohutukawa as Bonsai

August 7, 2021Bonsaiplace 4 Comments

In November 2015, the very early days of this blog site, I wrote about Metrosideros excelsa or Pohutukawa as Bonsai and included a few photos of these magnificent trees in nature. This tree is also known as the New Zealand Christmas tree. The link to that blog post is here.

https://bonsaiplace.net/2015/11/29/pohutukawa-as-bonsai/

For this blog post I will style a Pohutukawa as a Bonsai. As can be seen from the photos in the linked post, these trees very naturally present as multi trunks with great root structures and the very prominent aerial roots. it is this root structure and especially the aerial roots that make these trees ideal for root over rock designs. This tree will not be a full root over rock, but a rock will be placed next to it with roots growing over the rock.

This plant was grown from a cutting for a few years and these photos clearly show that these trees are basal dominant. It basically means that it will keep on growing new shoots from the base compared to tree which are apical dominant where the new growth is at the top of the tree.

Close up of the multiple shoots growing from the base as well as visible aerial roots.

As can be seen from the photos above, the first step is to search for roots and in this case roots in the soil and not the aerial roots. I find it better to remove the top edge of the plastic bag and sometimes remove the bag or pot completely. The presence and position of roots, especially radial roots will help to determine the orientation of the tree. In other words, the front of the tree and the first ideas of what the design could look like. In this case quite prominent roots were found and spread around the tree which means we can now look at the above ground structure as the placement of the roots allow us to look at multiple design options.

The next step is to remove all unwanted growth. To stay more or less true to the natural growth pattern Pohutukawa, the decision was made to design a multi trunk tree with three trunks. Really only two, but the thickest trunk has a fork which visually looks like two trunks. All three trunks have different diameters which makes it visibly more pleasing. All inward growing branches are removed and decisions are made about the three trunks. This includes things like direction, placement and length. As the three main trunks did not grow naturally in the directions needed and the centre trunk needed to be compacted, wire was applied.

A lot of branches and foliage were removed. some of these will be propagated as cuttings.

Wire was applied to bend the branches and also change the direction of the branches.

The final product with a rock added to add visual weight on the right hand side and also allow a backdrop or prop for some of the aerial roots to grow over.

It is important that Bonsai trees are three dimensional. The best way to check that is to view the tree from above. Visual depth adds to the aesthetics and overall view of the tree.

As for all trees, the aftercare is now of the utmost importance. As the pot is not that shallow, not many roots were removed, but the tree will still be kept in a protected spot, out of the wind and cold temperatures. Watering is now also important as well as sun exposure. Just damp, not wet and limited afternoon sun is what is now needed for the further development of this tree.

Horticultural Processes and Bonsai: Respiration

July 24, 2021Bonsaiplace 1 Comment

We have already looked at Photosynthesis https://bonsaiplace.net/2021/07/17/horticultural-processes-and-bonsai-photosynthesis/ and Transpiration https://bonsaiplace.net/2021/07/18/horticultural-processes-for-bonsai-transpiration/ as two processes that are very important for plants and your Bonsai to stay alive. There is a third such process which is as important as the other two, but because the structures responsible for this one are not that visible, it is not that well known. Respiration is something that is done by all living organisms. It basically comes down to the exchange of gasses that is needed to survive, just like in a human being. We breathe in and out to get Oxygen in and to release Carbon dioxide. Well, plants need to do the same thing as Oxygen is needed for plant cells to survive and they also release Carbon dioxide as a waste product.

Intuitively one would then wonder how Photosynthesis and Respiration is balanced so as to make sure that the plant produces more Oxygen than what it will use itself. Respiration can be classified as either Aerobic Respiration (enough Oxygen around) or Anaerobic Respiration (not enough or no Oxygen present). The latter one is a problem for plants and something the Bonsai grower needs to be very aware of. The best example of this is in Yeasts through the process of Fermentation.

Looking at the diagram below, we can see how the two processes interact. The one’s products become the other process’s raw material (input) and vice versa.

Important points for Bonsai growers:

Water logged soil do not allow a good flow of air through the soil which means that there is very little to no Oxygen available for root cells to take this gas in. Due to myriads of bacteria living in soil, and some of these can live anaerobically (in the absence of Oxygen), the chances that these bacteria can cause rot and other damage is large. Best to avoid water logged soil.
Drainage: This aspect is linked to the point above, but important enough to elaborate. Good drainage will promote good airflow through the soil. It is almost like a suction effect in the sense that as water runs through the soil, air will follow and in this way increase the air flow (ventilation) through the soil and the end result is that you have happy roots and happy roots equals happy Bonsai.
Pots: Bonsai pots can be very small in relation to the root mass of the tree planted in it. That means less soil compared to a plant in a garden and this can also lead to less air in the pot. Training pots especially are important. At Bonsaiplace when we use timber boxes or even plastic containers as training pots, we always drill extra holes, not just underneath for drainage purposes, but also from the sides to increase air flow for respiration.
Hothouses and covering Bonsai plants or cuttings with plastic. The main reason why we do this is to increase the humidity around the plant. That helps to prevent water loss through transpiration and increases the heat to promote growth. Just keep in mind that through photosynthesis the plant will produce Oxygen that in turn will be taken up for respiration purposes and Carbon dioxide will be produced for Photosynthesis to take place through Respiration. Where the problem comes in is when you do not have leaves on the plant, i.e., cuttings or a deciduous tree. That means no Photosynthesis and although Respiration needs are low, it still takes place. Just allow fresh air to get into the plastic covering at times and this problem will be sorted.

The next blog will look at Secondary Thickening. This is the process through which plants produce wood and bark. Exactly what we want for our Bonsai trees. To make sure that you do not miss this one, please subscribe to our website and like this post. It is all free.

Horticultural Processes and Bonsai: Transpiration

July 18, 2021July 17, 2021Bonsaiplace 3 Comments

Have you ever wondered how water travels from the soil into the roots and then up the stem to the leaves? Well, here we go. The process is called transpiration and starts in the roots through a process called osmosis. This is the movement of water across a membrane from an area of higher pressure to an area of lower pressure.

Now I am going to confuse you completely. I already said that it starts in the roots, but the condition for the process to happen actually starts in the leaves. As the water accumulates in the leaves, the internal volume of the leaves now have a higher pressure internally compared to the atmospheric air. That means that the water leaves the leaves through a structure called a stoma. There are hundreds of these on the leaves and they can open and close depending on the plant’s water needs and the climate on the outside. Almost like little valves.

Now we have the picture on both ends of the tree. The water flows in through the roots due to water pressure in the soil, it moves up a bit in the tubes (xylem) as these are very thin and act like thin straws. Have you ever noticed how when you place a straw in water how the water level in the thinner straw is higher than the level in the water. That is called capillary pressure.

What now happens is all of these work together. The water is pushed into the roots, the narrowness of the tubes give it a bit of a head start and then the pull from the leaves draws it further up the stem or trunk and the flow happens. This can happen as fast or as slow as the conditions dictate. If everything is perfect, a continuous flow will happen, but as soon as something changes, the tree will adapt. Let’s say there is not enough water in the soil for the osmosis to take place. In other words the pressure is not high enough for the water to enter the roots through the different membranes, well, water will not be taken up and the tree will dry out.

At the other end things can go horribly wrong as well. Let’s say it is a very hot day and a dry warm wind is blowing. That means the pressure on the outside of the leaf is very low and if there is any water inside the leaf, this steep difference will cause water to evaporate or transpire through the stomata and if this happens rapidly and the cells lose their turgidity (pressure), it will wilt and lose structure. If this happens for too long, it is possible that the plant will dry out and leave this earth for Bonsai tree heaven.

Experiment demonstrating plant transpiration. A plastic bag has been secured over the branches of a pot plant. The inside of the bag has condensation on it from water transpired from the plant’s leaves. Transpiration is the evaporation of water from pores called stomata in leaves. The pores open to allow carbon dioxide to enter the plant for use in photosynthesis, but this also leads to the loss of water.

Before we get to the practical things to do and look out for, it is important to remember that water travelling through a plant will contain minerals and other chemicals that it absorbs from the soil. It therefore plays a very important role in the distribution of these minerals throughout the tree.

The practical things:

Watering is a very important part of keeping Bonsai and comes down to a balancing act to ensure that optimal conditions exist for the processes as described above to take place.
Make sure that your trees are placed in an environment that suits the watering needs of the tree. Plants with thin leaves that can dry out easily i.e., Maples and should be kept out of harsh sun and dry windy conditions.
Trees with smaller leaves or even needles (Pines) can withstand this a bit more as they have less stomata and a thick waxy cuticle that covers the leaf or needle to minimise the area exposed to sun and wind and therefore slow transpiration down.
Get to know the water requirements of your trees and if possible group trees with similar water requirements together.
Check the drainage of your trees regularly. This starts with ensuring that the potting medium / soil is correct for the type of plant. Plants that thrive in drier conditions will have to be planted in a coarser and free draining medium.
When watering, water from the top over the whole tree as it washes dirt off the leaves to enhance transpiration as well as photosynthesis. It also cools the plant down so not to lose too much water.
If the soil is too wet, root rot can occur. This is not necessarily due to something going wrong with transpiration, but more a case of the roots not being able to breathe. Yes, they have to breathe as roots consists of living cells and through the process of respiration, need to take in oxygen. More on this in the next article in this series. It is also a perfect living condition for fungus that causes root rot.
Other techniques to ensure the soil does not get too wet is to tilt the pot during long periods of rain for water to run off. You can also push a rod through the drainage holes through to the top to create a channel for water to run through. These are drastic measures only to be used in circumstances where you need to get rid of water quickly.
Soil can dry out very quickly in a small Bonsai pot. When you get to a situation where the soil is so dry that water on top just runs off the surface, break the surface up a bit and dunk the whole pot in a container of water. Wait until all air bubbles disappear and place it back on the bench.
Another thing to look out for is when the roots grow so fast that it basically replaces the soil in the pot and all you have in the pot is a ball of roots. It is difficult for the plant to absorb water under these circumstances. Prevention is better than the cure. Repot with fresh soil when necessary and treat your trees as if they are pets.
When pruning, cover the cuts with cut paste or something similar as you create a wound and in the context of this article, a leak. Plug the plumbing to support the flow of water through the tree.

Horticultural Processes and Bonsai: Photosynthesis

July 17, 2021July 17, 2021Bonsaiplace 2 Comments

It is a well known fact that horticultural knowledge and skills should be on par with the creative side of Bonsai cultivation as a horticulturally neglected tree will never reach its full potential as a Bonsai. It is therefore important that some basic horticultural knowledge and skills are mastered early on the journey towards Bonsai mastery.

This series of articles has it as goal to highlight a few processes in horticultural science and linking this knowledge to Bonsai creation and maintenance. We will start off with the most important one and that is Photosynthesis. Others will follow in subsequent articles.

Photosynthesis

A bit of knowledge relating to cell science will help here. In plant cells, usually where there is a green colour, you will find cell organelles called chloroplasts. Inside these there is chlorophyll, a colour pigment, and this one is attributed to the green colour in plants. This is where photosynthesis takes place. Photosynthesis is the process through which plants use raw material to produce food. The raw materials are carbon dioxide and water and with the aid of energy from the sun, food is produced and oxygen is made as a by-product of this process.

What does this mean for Bonsai? The most important part here is the exposure to light. Without this natural light source not enough energy will be available for this process. The second part is that there should be enough chloroplasts available for this process to take place. The significance of this comes in at pruning time. It needs to be at the right time as there should be enough energy / food stored to carry the tree through the period with either no leaves or very few leaves, as at this time food production will be limited. This is crucial for evergreens as the food storage or energy storage side of these plants are not as well developed as what it is for deciduous plants. See the process of transpiration in another article as it plays a role with this as well.

In summary:

Your tree should have adequate light for food production.
Your tree should have adequate water for food production. Water plays a role in other processes as well which makes watering a crucial task for healthy Bonsai growing. See transpiration as an example.
Adequate ventilation is necessary to allow atmospheric carbon dioxide to get to your tree. This is usually not a problem in the outdoors, but something to think about when you cover trees with plastic to increase heat and humidity for growth purposes or other climatic defensive reasons.
Pruning and defoliating. Time this right. Never defoliate an evergreen completely unless it is just a branch or two for the purpose of creating deadwood / Jin.
When positioning branches and foliage pads, make sure that top branches do not cover lower branches too much.

Bonsai – Good comes from bad.

June 5, 2021Bonsaiplace 3 Comments

One thing that is for certain when it comes to Bonsai as an art form is that it is never static due to horticultural and climatic influences. Then we have to throw pests, disease and the odd mishap into the equation as well. This little Thuja did meet up with a bug or two one night and the Thuja came of second best. Yes, whatever it was, ringbarked one of the branches and the first sign was that one branch changed colour. Obviously unhappy and on its way to Bonsai afterlife. What to do?

The damage and the discolouring of the affected branch.

Change direction and from an informal upright change character to start the next phase of its life as a wannabe literati tree. The on its way to death branch comes off and becomes a jin.

Next step is to wire the trunk to the top, give it a bit of a change of direction and reduce the foliage as with the potting comes a reduction in root mass.

The tree is healthy otherwise and with good aftercare will grow into its new life and again stand tall as a proud Bonsai somewhere in the future.

On its way! Twenty centimetres from the top of the pot.

Garden trees to Bonsai

May 30, 2021May 30, 2021Bonsaiplace 4 Comments

Let’s get one thing out of the way first. The term Yamadori refers to a tree lifted from the wild where it has spent many years, showing good age with features that will make a great Bonsai. When a tree is lifted from a garden or from any other place for that matter it is not a Yamadori, not even an Urban Yamadori as some people refer to it. Yamadori in my mind is for one thing and one thing only.

I have recently seen a photo of a very nice Magnolia Bonsai tree and wanted to try my hand at one. As luck would have it, a garden tree that was to be removed was advertised in my area and I jumped at the opportunity.

Examples of Magnolia Bonsai from various sources (Pinterest, Bonsai Nut).

What we have here is a garden plant that has been grown as an ornamental plant in a garden bed. It is a Michelia figo or a Port wine Magnolia. It had to be removed as the owners were in the process of remodelling this garden area.

Great was my surprise when I parted some of the branches and discovered that it is actually three trees. It is important to make sure that there are no irrigation or other hidden water or electricity services going close to or underneath the digging area. The first job is to reduce the branches and foliage to get closer to the trunk and this will also help with survival as the branch and leaf mass needs to balance the root mass. Through the digging process and also the potting process, the root mass will also be reduced. And then the digging starts.

This was an easy dig as there are no tap roots and especially the two in the back were in quite dry loamy soil and they came out with just a spade length pushed into the soil about thirty centimetres from the trunk and circled around each plant.

It is important to leave the site in a tidy state and in this case I also removed the green waste for the owners. Each tree received a good spray of medicine water. Medicine water for me is just a weak solution of a marine-based or algae-based tonic across all parts of the tree. Now it is homeward bound.

The best advice is to have the planting containers ready before you go, but probably not so practical as you never know how big the root ball will be. in this case I used plastic planting pots, deeper than what a Bonsai pot will be, but this is to allow space for finer root development.

The first thing I do is to work through the roots. Remove all of the old garden soil and in this case some fat earthworks as well. Next is to remove very thick roots and reducing the depth of the root ball. Leave enough finer roots to feed the tree. I also apply rooting hormone powder to the cut roots and sprinkle a bit over all roots. Depending on the species, but more importantly, the state of the roots, I also apply sphagnum moss to the cut roots at this stage. In this case I did not as there were enough roots and they were healthy.

Some heavy root reduction had to take place.

Next up is to find a possible front of the tree by finding the widest part of the nebari and lining this up with the best flow that the branch structure allows. This is also the time to now reduce or shorten the branches to fit this vision of what the future tree could like like in five to seven years. At this stage I do not remove all branches to limit the tree to just one or two styles or designs. In all three cases it is possible to highly likely that the main trunks will be shortened over time. as the pots are round there is no need to worry too much at this stage about the front of the tree for planting purposes. Just focus on what might be needed for future development.

Now for the planting. Good drainage is essential. The soil that I use for this type of planting is a 1:1 ratio of pumice and compost. These are broadleaf trees and will grow relatively unchecked over the next year or two. They will all be heavily fertilised as soon as new growth comes out. The compost base helps with this and the pumice provides the necessary drainage.

The soil is heaped up in a dome shape inside the containers, the tree is pushed down and wiggled into the soil, tied in with wire and then filled up to the top level. I use my fingers and then a rounded dowel to work the soil in-between the roots. All that is left now is to water the trees and to let them rest until spring when the feeding will start.

Updates will follow as these trees develop. I usually tend to keep one if I have multiples from the same type and sell the others. That just means that updates at times is on just one or two of the trees as the others might be making someone else very happy.

Lockdown Bonsai work.

February 28, 2021Bonsaiplace 2 Comments

We were supposed to have aBonsai Society meeting today, which would have been the first one in a long time. Last night at 9pm, a change in alert levels was announced which means that where we live, social distancing is in place and as the venue is quite small, not the best for safety in the current Covid climate. That was called off.

I had this tree that I wanted to work on at the meeting. Basically just a clean up job and then lots of wiring to set the foliage pads. It is a Pine tree and in the twin-trunk style. Here is the before photo.

And here is the tree after the pads were set.

Cleaning, Jin work, wiring and branches set. Pity some of the three-dimensionality disappears in these photos. Maybe I just need to get my photography sorted.

Off the back of a truck.

February 28, 2021Bonsaiplace 3 Comments

I had to hide the introvert in my today when a small truck went past us and on the back there was a medium sized bush / tree clearly on its way to be dumped. The driver stopped and went into a shop while we waited outside. When the owner came out, I asked him if the tree is going to be dumped and when he confirmed that, I pulled out my Bonsaiplace business card and told him that I can create a Bonsai tree from the tree and he promptly agreed that I could have the tree.

Just a week ago we had a couple came to our private shop who had the idea that Bonsai are a specific type of tree and that you can grow them from Bonsai seed. I love these situations as it allows the educator in me to come out. This man (owner of the tree on the truck) said that it cannot become a Bonsai as it is not a Bonsai tree. Guess what? Out came the educator again.

Anyway, off we went with the tree in the back of the Bonsai mobile, speculating what type of tree it is. On arrival at home, I used a plant identifying app with no succes. In the process of cutting the branches off, I found a discoloured flower which looked very much like a withered Gardenia flower. I guess it is now wait and see and do more research to find its name. During this time it will have to be kept alive.

The tree and Snoopy, my Bonsai apprentice.

It does have some feeder roots and after I cut the branches, left it in a bucket of water to just chill a bit and hopefully get some sap flowing. As I do not like waste, I very cheekily took some of the roots with feeder roots intact and planted that up as well. These I will treat the same way as what I do with Maple root cuttings with which we have had great success.

All is now potted up, watered and in a sheltered position. Tonight I will start with the weekly tonic of seaweed extract to help stimulate more root growth.

The root cuttings with a thickish branch as cutting. That is me trying my luck. Let’s wait and see.

Below are three Maple root cuttings in development.

Slanting Redwood Styling

February 8, 2021Bonsaiplace 2 Comments

This Redwood came to me just over a year ago and ended up on the bottom shelf as it was not a high priority to work on and a little bit ugly. Today was the day for this one to get attention and even if I have to say so myself, the ugly duckling is now well on its way to become a beautiful swan.

It has a very straight trunk and was chopped before it came to me. The taper is minimal, but can be enhanced with a bit of carving at the top. More interest can also be had by creating an interesting Jin out of the dead branch at the bottom. Most of the growth is at the top which normally lends itself to a Literati style tree, but in this case the trunk is nowhere near what one would like to see in a Literati style tree.

Lots of growth right at the top and spread radially around the trunk at this point.

Decision time and it is to slant the trunk and then for the branches to droop downwards at an angle following the trunk line. Normally with this style the branches on the open side, in this case to the right, are longer than those on the closed side, or left side in this case.

The growth is still relatively young with no real solid branches at the top, but it is important to spread the branches / leaves radially out to enable all green parts to receive maximum light.

This Redwood will now rest until Spring, be fed profusely in a sheltered spot.

Literati Juniper First Foliage Pad work.

February 7, 2021Bonsaiplace 2 Comments

This Juniper came to me as a very neglected tree about a year ago. After a solid nutrition program and tender loving care it is now ready to get some work done on it. The major job will come in Spring (seven months away) when the first big repot with fresh soil will take place. For now, let’s get the pads placed in a better position and also do some thinning of the vigorous growth.

The music is in the background, not embedded in the video and stops at some stage. No talking, just working.

Nursery material to starter Bonsai

February 6, 2021Bonsaiplace 1 Comment

What does Dolphins and Bonsai have in common?

One of the fastest way to get a Bonsai collection going is to find material at your local nursery to develop over time into a stunning Bonsai. Yes, it takes time, but still beats starting from seeds or cuttings. Although My private collection mainly consist of mature trees, I regularly still work on anything from cuttings to nursery material. The main reason for this is to generate stock for my wife’s fledgling Bonsai shop.

Yesterday I bought this Juniper from our local Bunnings (hardware store for those outside of Australia and New Zealand). As luck would have it, I just recently saw a mature Juniper on Instagram with a slanting main branch and a smaller branch following the contour of the main branch. Another coincidence is that I recently went on a Dolphin watching trip on Guardian, the boat used by Dolphin Seafaris in Tauranga, New Zealand. Where does this fit, you may ask. Well, there were a lot of baby Dolphins with their mothers, swimming in close proximity of the mother and mimicking what they do. It might also have to do with the fact that they suckle on mommy dolphin twenty times per hour! Need to be close for that.

The first task is to clean the tree up as selecting the front was a given with the shape I wanted it to have. The clean up consists of removing unnecessary branches, just one in this case, and then all the growth pointing to the bottom and on top of the branches. It also includes cleaning the crotches between the main branches and the lateral ones. It just makes it a lot easier to apply wire.

Then the wiring starts. The same gauge wire was used on both branches as the smaller one also needed to be twisted and bend around to follow the main branch line. You cannot just bend it over as the leaves will have their undersides on top then. It needs a twist as well.

The final product. The main slanting branch represents the mother Dolphin and the smaller one the baby Dolphin. There is my memory of the Dolphin watching trip now captured in a starter Bonsai. Now for it to rest, watered, fertilized and kept out of harsh climate conditions.

Literati Juniper work

January 30, 2021Bonsaiplace 1 Comment

This Literati style Juniper came into my collection as a very neglected, half of the branches dead and under nourished tree.

Today it was time to get some wiring done through to the growth points. The previous and first wiring from me was just on the main branches to set them. As can be seen, the branches that were dead or with no hope of recovery were all jinned and these branches will be refined with sanding paper and lime sulphur later on.

The living branches, only three of them have responded nicely with new growth and these are kept in tact at this stage to get as much energy as possible to the green and new growth. This tree only received liquid fertiliser in the form of a marine plant / kelp conditioner with one dose of a granular feed, balanced NPK.

Here are some of the before photos

This type of work is quite light and I only used two thicknesses of aluminium wire and a wire cutter for this job. The coffee is not really optional, but I did have the mandatory glass of wine just before this job with a meal.

These are the after photos:

After photos. The job took about 30 minutes. It is light work.

This tree will now rest and carry on with its fortnightly application of liquid food. This is applied over the leaves as well as the soil.

The Addiction Strikes – Collecting Bonsai Trees from Nature

July 22, 2020Bonsaiplace 6 Comments

For us in the Southern hemisphere it is that time of year when Bonsai enthusiasts pack their bags, collect their tools and load up on enough supplies to go Yamadori hunting. Yes, we go crazy to get our hands on raw material that we can grow on to become aesthetically pleasing Bonsai.

The big questions related to this activity is based on safety and ethics. How do I do it safely and how do I do it ethically?

Safety always comes first. It starts with weather conditions, through to the equipment needed to keep you safe and also having a plan. If you go on your own, make sure you tell people what your plans are, where you will be and what time you will be back. If you are visiting a remote area and there is no cell coverage, then you will need a personal locator beacon.

Always make sure that you have enough food, shelter and clothing to last for three times longer than what you expect to be out. A safe way to do this is to write a list of what you will need and then use it to pack your stuff. On your return, revisit the list and update it for next time.

I see many people on a Bonsai hunt with very little eye, hand or feet protection when things like spades, saws and power tools like chainsaws are pulled out. Do not forget your ears when the latter starts up.

A big issue that we need to have a lot more conversations about is the ethical removal of trees from nature. It starts with permission to do so and really comes down to the survivability of the tree once lifted. There is a skill to this as well as the transport and after care of the tree. You need to know the species. Is it something you can lift and transport bare rooted or is it something that you start the preparation a year ahead of the actual removal of the tree?

My general rule is that if I am not one hundred percent sure that the tree will survive or that I do not have the skills to care for that specific specie of tree, then I leave it where it is. Not a fifty percent chance, a one hundred percent chance.

There are many You Tube videos and a lot of information available on the technical aspects of how to do this. I have always wondered about what some of these collected trees look like after a few years. Responsible collectors follow their videos and photos up with progress videos and photos. Probably because they have live trees to show for their efforts. Those are the ones that you want to look at or follow. If you never see these trees again, stay away from these people.

In conclusion, think, plan and over organise your trip. Have all the correct equipment needed and only take what you have permission for and what you can keep alive.
