Yamadori – collected in Spring 2018 – Part II

Yamadori – collected in Spring 2018 – Part II

So, as promised in my previous post I will follow-up with the new collected material in fall of 2017 and spring of 2018 as well. All these pictures were taken in early April 2018 and by now all their buds are swelling and many of these trees are already leafed out. I will present in a future post their progression as detailed as possible, but it takes me quite some time to shoot pictures of so many trees to follow their growth.

A Carpinus with elegant trunk movement.

A Carpinus in cascade style. It has a too long trunk for cascade style but it has an extremely well formed canopy for this. The trunk issue will be solved in 2019. If the tree will be vigorous through this year, in May 2019 I will airlayer it in order to obtain a shorter trunk with some possible nebari to get it ready for repotting in 2020 into a tall cascade dedicated ceramic pot.

One of my favorite from the collected material of 2018 is a raft Carpinus with aerial roots as well. It is an awesome tree and it needed a custom made wood container. It is about 1m long. It seems to be doing just good as at the moment of writing this post it is already in leaf.

Another semi-raft Crapinus that is by this time full of leafs and proving to be quite vigorous.

Still in the Carpinus selections, one with aerial roots.

Probably the last Carpinus that I will mention in this post, is one with very dense ramification and the size of the branching from thick to medium to thin being very fast in narrow distances from the trunk. I think that in order to obtain such ramification on demand it takes a lot of skills and maybe some luck as well.

As you probably observed, I collected quite some Carpinus yamadori. I am fascinated by the diversity of styles and changes that I found in yamadori style Carpinus. In my opinion, with this species you can either find or create in time any stile you want from the wide perspective of bonsai styles. Even now, as you can observe in my pictures, it is able to grow aerial roots that usually is common for ficus trees. Of course these so called aerial roots were under ground when the trees were collected, however their feeder roots are now under soil level while their wooden part was exposed to create the perspective of tropical aerial roots.

In future posts I will present other species as well, but I felt like dedicating Yamadori – collected in Spring 2018 – Part I and II only to Carpinus species.

Thanks for the visit,
M.

 

 

 

Yamadori – collected in Spring 2018 – Part I

Yamadori – collected in Spring 2018 – Part I

Here in Romania, we had a very soft and warm autumn and winter as well. This tented me to try and collect as much material as I was able, hence starting from November 2017 till April 2018 I took advantage of the warm weekends and went out there scouting and collecting new trees. This way, I have reached a number of over 60 acquisitions some with high potential already, others considered future investments. However, all of them were collected, potted and kept until a few days ago in my basement where the temperatures rarely drop below 7°C. It is a fact that at temperatures between 7°C and 12°C, only the trunk and the branches are dormant. The roots are growing in a slow rate, but still growing. I considered this  an advantage for me, giving the trees a few months to develop new roots in order to start their establishment in the new containers and the new soil, way before they get completely out of their dormancy period. Through this period I was paying attention to not let the soil from the pots dry out completely, still let them dry to the point where oxygen was able to reach the roots. This is important to offer the correct balance of water and oxygen particles around the root system. In doing so, one can make sure that the roots are being treated with proper care and the best survival condition is facilitated as well as their development.

I will not post pictures of all the 60+ trees in this post nor in the following ones, but I will present those that have quite a potential at the moment. However, future posts will slowly cover the entire collection, presenting progression from the collection moment and their development in time. So, this is the first of a series of posts that will probably last for the entire 2018 season, detailing not only the development of the trees, but their after care, handling and fertilization.

A wild Carpinus collected from the top of a rocky hill with a lot of movement and even aerial roots.

A shohin Carpinus, presenting a lot of movement, nice root flare and age.

Semi-raft Carpinus, bent into position using copper wires accomplishing nice movement over its branches.

Wild movement, wild trunk wild aerial roots, this is a wild Carpinus.

Wind blown style Carpinus.

A small shohin Carpinus with an awesome nebari and branch distribution.

Hope you find these trees as full of potential as I do and stay close as more pictures of other ones will come in future posts.

Thanks for the visit!

Acer Campestre and Robinia – End of season 2017

Acer Campestre and Robinia – End of season 2017

I continue my journey of fall pruning with other two species besides Carpinus and Fagus trees, presented in the previous post. The time came to prune my Acer Campestre, or field maple and Robinia yamadori, all collected in spring 2017. These trees grew all year round quite well hopefully accumulating enough energy to push hard in 2018. This year I let them do their think and go as wild as they desired, being the first year after collection. As they went dormant, it is about time to prune them back hard, to start their structural design.

The first Field Maple pruned is in the images below, before and after pruning with an additional bird’s eye view to see the final canopy structure. It created many buds with very short internodes, and I hope that it will behave the same next year as well. As seen in the first image, all the branches grew strait, with no movement and a too high density of buds emerging from the same node. If not pruned, these buds will swell in spring and they will create in the branches thick nodes at their base. So, I considered important to start all over the entire structure, up to an extent of thick branches.

I cleared mostly the density of chaotic buds existing all over some branches by pruning back to old wood. Doing so, in 2018, as soon as they will start leafing out, I will wait till the new branches reach maturity and apply guide wires to give movement and place the new branches in the positions that I feel like it advantages canopy design.

In a bird’s eye view, one can see that the overall architecture of the new canopy is structurally in equilibrium around the tree, giving in the same time layers of the future growth.

Another maple that I pruned has a nice trunk that I liked from its beginnings but all the side branches were too strait with very long internodes. I gave it a lot of time to figure out what is the best way to obtain a nice canopy in the shortest period of time, but the only solution I found suitable was to prune back nearly all the branches to the main trunk and practically start from scratch the entire tree. Such operations, push back 3 to 4 years of development, but at least gives you the opportunity to renounce creating a bonsai on compromises.

So I did, I cut back drastically to the trunk. I left only some thin branches that I will take advantage of when creating the new canopy. I hope however that pruning so hard back will push out new buds and I will be careful in the spring, to leave only those to develop that are in the right positions. The rest of them, will be all removed as soon as they will be visible on the tree.

In the top view of the tree it can be seen that not much of the original structure remained. Also, when collecting this yamadori, it had a strange one-sided growing root system and this is the reason why it is placed in the contained so off center. I will repot the tree in 2019 Spring and then I will start removing from the length of the long one-sided root, trying to center the tree in the pot.

The second species that I pruned is the Robinia yamadori from my collection. This species in particular is quite tolerant to human intervention, responds well to pruning and to repotting. I let it grow wild all season to ensure a good root system in the pot as I have a special plan with this tree.

I pruned the right sided stubs and worked the cut to shape it close to a natural wound. I did not apply any healing paste to it because I want to let it dry out and die back at the surface. When pruning, I left on the tree only those branches that are in right position for the new canopy and in Spring 2018 I will change the angle of the trunk as exemplified in the picture below. For this I can do 2 things: either I do a parallel to the ground cut of the plastic container in this angle, either I repot the tree. If I will repot it, I will not remove all the soil, but I will remove only from the bottom and the top to be able to give it the proper angle, then I will move it back probably in a more flat container.

Another Robonia yamadori collected in Spring 2017 has a multi-trunk structure and had a quite vigorous growth this season. Only in one season, I think that its ceramic container is already full of roots as I had to cut many of them from the tray below the tree, spread out via the drainage holes.

During 2017, one of the trunks died and I was somehow glad it happened because this was facing directly the viewer from the considered front of the tree. I cut it back to an extent to leave a stub that I worked to look like a natural branch that broke. I also burned the wood and I am sure that in a few months especially after rain next year will age the stub it will look very natural. I tried to prune the tree in order to reach different layers and cut off all the branches that were growing directly to the inside of the canopy

In a top view of the tree, the three remaining trunks are very nicely distributed, somehow in an angle of 120 degrees, rounding upt the entire structure and advantaging it’s front view.

What I love most about Robinia species is that even small trees have this aged bark and even wounds or dead wood becomes fantastic when weather conditions influence their aspect in time. One important thing I would mention about Robinia is that they love direct sun and require a lot of water. During growing season, they can consume the water from the container on less than one day comparative to the other species that stay mois for 3 to 4 days.

Fagus sylvatica – End of season 2017

Fagus sylvatica – End of season 2017

In the previous post I presented the process of pruning my Carpinus shohin collection. To continue I chose to prune my Fagus Sylvastica trees. All of these were collected from the wild in Spring 2017. As seen in the Yamadori progression – spring to fall 2017 post, all these had a quite vigorous growth this year and all reached Autumn stabilized in their containers. When I collected these trees, I pruned them just enough to decrease their size, but I left on their branches as many buds as possible. Doing so, I wanted to make sure that when these buds will swell and open, the new leaves will promote new root growth in the pots to replace those lost during collection. Now, after a good growth season, it is time to start pruning hard to create the desired shape by going back closer to the trunk and the thick branches.

When pruning Fagus, or popularly called Beech, it is important to leave on the branch at least one bud to make sure that the branch will not die back. I was lucky with these trees, because even if small, there are many back buds on the thicker branches, so I was able to prune hard the trees.

The first tree had a very dense canopy with many buds on the new branches but too far from the thick wood. Also another problem was that at the point where the main trunk divides into two, in fact it divided into three. So, I pruned it back drastically and I created in fact two levels, one upper one that will be the new apex of the tree, and a lower one that will ensure an equilibrium over the entire structure. In a bird’s eye view it can be seen that the tree has an even distribution of the remaining branches. On their bark there are small buds that will give me next year a startup for a completely new ramification system.

A second Beech yamadori with more or less the same characteristics as the previous one needed a hard pruning to go back closer to the trunk and the thick branches. I simplified a lot its canopy and at the moment it is not so impressive as it was just before pruning. However, I will now be able to guide with wire the new growth from next year on, and by this I will take over the control of the canopy’s shape. Many times, it is needed to give up on a apparently nice design to reach a certain desired one.

The last Beech yamadori that I collected in the Spring had an up informal character or close to broom shape. The trunk-line has a semicircle shape and in my vision, I was thinking to mix the up informal character with the trunk shape, continuing it on one branch that needed to be moved in a proper position. The issue was that the branch was quite thick. Fagus wood is very hard to bent when it is thick and especially when it is dormant like it is already. Using thick wire around it is not a solution. However, I wound around this branch thick wire, but not no bent it with this wire, but to distribute the bending force evenly over the branch’s length. The bending itself was done by a pull-down wire hooked to the tip of the branch. Comparing the before and after pictures, one can see the huge displacement of the branch. If I would not apply that thick wire to distribute the bending force from the tip of the branch, I am absolutely positive that the branch would break. Doing so, I was able to displace it in a wide angle and it was a safe operation.

I kept however the general broom aspect of the branches in the canopy because I want to create the illusion of an umbrella shape apex of the tree.

 

Carpinus pruning – End of season 2017

Carpinus pruning – End of season 2017

As autumn is now already here for some time now, the leaves of my carpinus shohin trees got brown marking the end of this season and telling me that they went dormant till spring. Because I like to take my time when I prune my trees, I start pruning them from autumn gaining also space inside my cold shelter where I house the trees till temperatures are above freezing in spring.

Methodically I started this year with my smallest trees. These were all collected in March 2017. One season growth already established the trees in the pots and also gave me quite impressive elongation of the thin branches.

The tools that I use are classical bonsai pruners such as concave, knob, scissors and classical garden pruning scissors for very thick branches.

The first tree that I pruned is a multiple trunk with a very nice taper. This tree was extremely vigorous this year and it was mandatory to prune it in the summer too, even if this a habit that should be avoided in the first year after collecting from the wild. In the first picture is the tree before pruning and the next ones are after pruning, a front and bird’s eye view.

The real shohin carpinus trees that I have are quite small, they have a height of about 12-15cm and a diameter after pruning of about 20cm.

The next tree is my favorite one. I found it close to a field that often was visited by sheep and I thing its size is given by these continuously eating its new fresh growth year after year.I had to use thick wire to move thick branches into their final position. It was very challenging because carpinus wood is very hard to bent and I ha to put a lot of effort into it. But finally the branches reached their right position.

The last carpinus shogin is the smallest of all. I pruned it back quite hard to try and create dense ramification close to the main trunk. Hope that next year it will bud back on the remaining branches as expected.

 

I apply to all the cut wounds healing and callusing paste by this ensuring that water with diseases will not enter in the cut places and also this will increase the callusing process.
