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!
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.
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.
