Progression of collected trees of 2018

Progression of collected trees of 2018

At the moment I own about 70+ trees that mainly are deciduous collected in 2017 and 2018. As it was exposed in my previous posts, I own several tropical ones as well. However many of the deciduous ones collected this year responded well for the collection and re-establishing process. I usually organize one shooting in each season for each tree and in case I do some major work on them I shoot that operation as well. As follows, I will present the progression of some of the trees that developed nicely over the spring and summer of 2018.

My largest Carpinus in April, then May (before and after), pruned back to two leaves and in July

Another Carpinus that grew well this year and I think I will repot it by next spring. The pictures are taken in April, then May (before and after), pruned back to two leaves and in July.

A flat Carpinus that just loves the new soil, still pictured in April, then May (before and after), pruned back to two leaves and in July.

As they call it in France, “le pièce de résistance”, my raft Carpinus in the wood box. Pictures are taken in April and July. This was not pruned at all this spring.

I bought from a local nursery in June 3 Junipers to be styled in shohin cascade bonsai. After the first prune and reduction of nursery soil, these responded well developing new growth. In spring 2019 I will repot them into their ceramic containers. The pictures were taken in June and July.

I will end my post today with a tree that I collected in spring this year from my father’s garden. In fact it is a grape tree that seems to grow just lovely and it already has grapes on it.

Hope you enjoyed visiting my blog and hope to see you back soon.

Thanks,

Airlayer separation – Ficus Benjamina

Airlayer separation – Ficus Benjamina

In August 2017 I started a new project airlayering a ficus benjamina in the post entitled Ficus benjamina airlayering based on a technique that I read about somewhere on the internet. I let the tree develop for about 10 months and then in May 2018 I decided that it is time to do the separation. Looking at the root system that was developing inside the bag in the airlayer, I considered that there were enough feeders to be able to supply the tree after separation, taking into account that I was planning to do a preliminary structural pruning as well, so a large quantity of the foliage was to be removed from the canopy.

As it can be seen in the picture above, there was a large number of leaves that I intentionally left on the canopy because the principle is simple: many leaves are photosynthesizing carrying sugars down to the roots right in the layer under the bark. As the bark is interrupted, the sugars cannot reach the roots in the soil of the tree, but these will promote creation of new roots at the point where the bark is interrupted. So, the more leaves that move sugars on the tree, the faster the roots in the layered region will grow. I wrapped the bag of sphagnum moss in aluminium foil just to prevent the light from penetrating it and disturbing the roots development because as we know, roots are photo-phobic plant parts.

After removing the plastic bag and started moving around the moss, I found many roots that where keeping the moss together compact.

Overall, the tree and its new root systems looked like this. To be honest, I was glad to find many roots there that I knew will be more than enough to sustain the separated tree, but disappointing was when I realized that the moss cannot be removed to comb out nicely the roots. When I insisted on removing the moss, I observed that the roots were so tangled in it that the risk of damaging them was inevitable.

So I cleaned out as much moss as I could without damaging the new fragile root system, and perform under-cut of the thick useless remaining trunk. The problem is that I knew at that moment that I will have to pot the tree with the moss package and with the roots chaotically tangled inside it. Another disadvantage of the moss is that it is a sterile moss and the instructions on the bag with which I bought it claims that it is treated to not rot. So I know that it will stay there close to the tree for a long time. Unfortunately, I had already done another airlayering on a Bougainvillea tree using sphagnum moss. However, I will never use it again for this purpose, and instead I will use a plastic container filled with flower potting soil that I know I am able to remove and place the new roots in proper positions.

The final product of the potting and pruning for preliminary stilling is depicted in the picture above. I did not do any wiring nor serious pruning to shape the tree in its final position. I pruned it just to give a preliminary architecture and leave enough leaves to help the new roots to establish in the new soil. Because in the middle of the pot, right under the tree there is the moss and around it towards the edge of the container is my classical bonsai soil mix, is another drawback because practically in the pot there are regions with different water uptake and different drying coefficients. This will make the watering process a little difficult but, it is as it is.

This entire process of separation took place in May 2018, as already said before. In July 2018, the tree was already getting into shape pushing new growth and letting me know for sure that the root system is working and developing new roots as well.

This is the way the tree looked in July 2018. I am planning on pruning it and wiring it in the end of August, starting of September and then let it grow over the winter till March 2019 when I will start pruning it back harder to work on the ramification more.

Hope this helps you and thanks for your visit!

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.

 

Ficus Benjamina Variegata – one season stilling

Ficus Benjamina Variegata – one season stilling

In January 2016 I bough from a supermarket a Ficus Benjamina Variegata that looked more like a bush at that moment. The choice was based on its multiple trunks and the final idea was to fuse them into one think trunk. I took good care of it, keeping it over the winter on a sunny window sill, fertilize it every second week, never prune it and let it elongate as wild as it felt to do so. By late Spring 2016 it grew quite a lot and probably doubled its height. I considered it is time to start working on it, motivated also by the ambient temperatures that were already increasing. Longer days with an abundance of sunlight were at my disposal now, so I had all the necessary ingredients to start the process of fusing the trunks.

Preliminary I pruned back the Ficus, and removed closely all the leaves from the branches.At that time I did not have at my disposal natural raffia so I used instead of it used hemp cord. As you can see in the picture below, after finalizing  pruning and warping the tree. Using hemp cord proved to be a bad idea. At the lower side of the trunks, due to higher humidity as the cord is close to the soil, this rotted fast. Even this was no problem, but it promoted rotting of the trunks.

By early spring 2017, only one trunk remained. The rest of the rotted away and I removed them as deep as possible from the soil. One interesting thing is that one trunk fused to this remaining one. Its base rotted and now it is still there sicked to the main trunk. Details about this are depicted later in this post, just roll it down.

I was not too satisfied with the progression of the tree over an entire year. In early summer 2017 the tree looked more like a stick with some branches and leaves here and there. Far away from any of the initial ideas that I had with this tree. I knew at the moment what I had to do in order to thicken the main trunk and the side branches. I had to place the tree outside and expose it to continuously changing weather conditions such as rain, wind, sunshine, warm and colder rays. Especially wind, because it moves the trunk and the branches helps a lot in a fast thickening of the wood as it tries to repose to bending.

I wired with copper wire the branches into the desired positions and covered the soil with natural fertilizer and then with moss to make sure that humidity is kept constant when keeping the tree in full sun. This process started in May 2017. The tree was watered every other day, excepting rainy days when it was not necessary.

Wiring the branches into their correct position gave a nice distribution of the leaves both to ensure forming levels of branches with leaves and also making sure that sunlight penetrates and reaches the trunk and the leaves from all sides. A top view of the tree proves this. Too long branches were pruned to keep a nice harmonic overall shape of the tree.

Thicker branches required doubling the wire to make sure that those will stay in the desired position. In the picture below one can observe that the top branches were bent to form lateral pads. To create the force and the tension in the wire required to bend them and to make sure that aggressive windy days will not move the branches in other position, doubling the wire has to start from the trunk creating few spirals around it and only after that to be wired around a specific branch.

As expected, by early fall (September 2017) the tree had a serious evolution. The trunk and the branches thickened a lot. The base of the trunk actually doubled its diameter. As it can be seen in the picture below, the process was so aggressive that the wires cut inside the wood, in some regions of the tree they were so deep that the actual bark of the tree was maybe 1mm higher than the wire. I know, the wires should have been removed much earlier to avoid scars in the bark. My experience with Ficus species proved that such scars are many times advantageous.

On Ficus species, such scars will heal in less than 6 months completely. The nice thing when healing is that on the surface of the bark a texture remains uneven due to those former scars and this by all means adds to the value of the tree and proves to compensate the simple bark present of Ficus species. So, to be honest, I left intentionally the wire there to bite in and create those scars. I always do so!

I was writing earlier about the fusion of a former complete trunk with the main trunk of the tree. In the picture below one can see where the old trunk was cut of as it was dead and rotting. It is fused to the main trunk, it has branches and leaves and lives very well. Even more, when I wrapped it for the first time with hemp cord, I passed between the two trunks a branch and now it is growing from that fusion point, as it can be seen in the picture below.

As the temperatures outside are quite low now, the tree was moved inside. I have removed all the wires of the tree in order to start the healing of the scars. However, branches that still were not in the desired position were rewired making sure the new wire is not inside the scars created by the former wires that held the branch through Summer. In the picture below, the pads formed are already visible on the Ficus tree. Of course there is much more work to do, but comparing the overall design of the tree now, with the moment at the beginning of Summer, one can say that a big step forward was made.

From the roots there are two new trunks that I intend to use to create a new lower level of the tree. I wired these too into the right position and trimmed some of the branches that were growing strait up. All that it remains now is to winter the tree inside, keep it warm, in sunny  window sill and fertilize it with liquid fertilizer every two weeks. In 2018 I will move again the tree outside and repeat the experience from this year. Doing this, I think that in 2 or 3 years I will have a quite nice tree ready to be called bonsai by all means.

Yamadori progression – spring to fall 2017

Yamadori progression – spring to fall 2017

In spring 2017 I collected an abundance of species from the surrounding of Cluj Napoca. Nearly all the collected material survived and some of them grew quite vigorously through the 2017 season.  I have lost an Oak, one Carpinus and one Field Maple. The remaining ones suffered some sunburn in mid August due to extremely high temperatures.

In the pictures below there is a huge Carpinus that I have found on a top of a rocky hill. After pruning it back heavily I was amazed by the structure of the tree. That was the moment when I decided that even if it is a big stub, I have to take it home, against my habit of orienting my developments in the region of shohin style. The pictures were taken just few minutes before starting to dig around it. Collecting the tree was a very time and effort consuming job to save as much root-ball as possible.

After potting the tree, it bud out quite slow. However, after it did, I applied a light dosage of fertilizer and it started to grow extremely fast and vigorously. The picture below was taken few days ago (October 2017). The tree was left to grow wild for the entire year to stabilize a new root-ball. It did and I know that because the drainage tray under it, in mid summer, was already full of feeder roots. I cut them back to motivate the tree to replace those with new ones inside the plastic pot that was placed into.

Another Carpinus collected in Spring 2017 is in the pictures below. This tree proved to be the most vigorous tree of all. Immediately after collecting and potting it, it started growing very vigorously. By end of spring, it had shoots with 5-10 leaves. Only because I realized that the tree is strong, I pushed the limits and pruned back the new shoots to two leaves. Normally, in the first year it is not recommended to do so because the tree needs the leaves to create sugars and carbohydrates to grow new roots and to prepare for winter dormancy. However, I new that this tree will be able to take a new pruning. It did, and now, in fall, it has new growth that is more than enough to prepare the tree for dormancy.

Still in the Carpinus Yamadori universe, I collected in Spring a shohin tree that was already “styled” by the sheep that feed with its leaves year after year. It has a nice short and quite thick trunk, movement in the branches and a dense ramification from thick to thin to thinnest. It grew very nicely over the spring and summer. In August however, it suffered sun burn, still visible in the last pictures. At that moment I thought that only the Sun was responsible for the burn. I know now as a fact that I had 50% of the quilt because I did not reduce the fertilizer quantity in the hot days. This made impossible the uptake of sufficient water by the roots to serve the transpiration at the leaves surface.

Still in Spring 2017, I collected two Fagus (Beech) Yamadori. Both are in the range of shohin stye with nice movement in the trunks and quite dense ramification. One of them (visible in the last picture) has a tendency of reverse taper. This did not stopped me to collect it. The plan is to work on the ramification of the tree for the next one or two years. In this time the tree will stabilize well in the pot and I will perform an airlayering in the area where the reverse taper stars. Using a thick copper wire around the cutting performed for the airlayer, I will promote a nice nebari that will complete the structure of the tree.

I am a fan of Acacia bonsai. I just love the trunks of Acacia trees how they look extremely aged due to the rugged bark. I collected a tree and potted it in a taller container as it had quite long thick roots. From the original structure (first picture) I had a die back of of one branch, and somehow I lost half of the canopy. At the moment I was disappointed. The problem was solved one evening when I tilted the tree and saw a new very nice angle that I was getting in this new position. So, when I will repot the tree, I will fix the new angle by the tree’s new position in shallow pot. I will probably repot this tree in the spring of 2019. The deadwood on the lower side of the trunk comes in addition to the tree’s overall value.

Walking the woods, I found a very nice Fern (Asplenium trichomanes) with small leaves. It already grows now for two years in this pot. I collected it with soil from around it, taking even some rocks and rotting leaves with this soil. It seems to be liking it in this pot. I keep the fern out of direct sunlight and I give it once in a while liquid fertilizer.

Starting spring I will continue such series with progression of these trees and also others that were not included in this post. Pruning, wiring, carving and repotting stories will continue the one I have started today.

Keep close!
