Major Changes for Big Larch Forest
I bought this tree in December 2012. Being an established forest, it had some nice character but also some major challenges. Besides the unsuitable pot, the forest had far too much symmetry and the branches were too “stubby”, for lack of a better word. The variation in the trunks (diameter and height) is limited, Some of these things would be easy to correct, but others more difficult or impossible. The year 2013 was spent just growing it out and lightly pruning to develop a more elegant branch structure.
As a side note, this tree spend the entire winter out on a bench completely unprotected. This was the coldest winter in southern Ontario in over 20 years with many days in the -20 Celsius range and a few in the -30s. Fortunately there was a lot of snow and this larch was right at home.
The first step for this year was to wire everything. This probably took 12 hours, spread out over several days. Conifer forests just take so much wiring, it can be overwhelming.

After wiring. No branches have been placed yet. Note the number of new branches compared to the Spring 2013 image.
The next step was to plant it in a more suitable container. This slab was custom made for the forest by local potter Geoff Lloyd. One thing we neglected to think about was the front of the slab. The slab was designed for a forest pointing to the right, yet this forest obviously points to the left. As a result I ended up using the “back” of the slab as the front. It is still an attractive side, but has a slightly less interesting profile than the other side.
The next step was removing the tree from the old pot and raking out the perimeter of the root ball. The bottom of the rootball was not touched at all. The perimeter needed to be raked out quite a bit so it would fit within the boundaries of the narrower new slab.
A muck mixture was made to mold the rootball within the contours of the new slab. The mixture was something like 2/3rds humus, 1/3rd chopped sphagnum, and a cup or two of akadama dust, plus water as needed.
After mucking the perimeter, the rootball was completely mossed. The purpose of this was mainly to prevent erosion of the freshly worked rootball, but of course there is an aesthetic benefit as well. Besides the muck, no new bonsai soil was added. The roots still have plenty of room to grow in the original root mass. Larches are perfectly happy with dense matted root balls with scant amounts of soil. It will be a long time before I need to refresh the soil again.
Now that the tree was in its new container, the branches could be placed. Many guy wires were used to reposition the trunks. Again, the goal was to give this tree a definite leftward movement. This was accomplished by pulling most of the trunks to the left and extending out the leftward growing branches while compacting those growing to the right side. I find forests to be immensely challenging as there are so many design considerations. The branches and trunks were adjusted again, and again over several sessions. I am still not 100% happy with the design but I think it is the best I could do without removing or adding trunks. That is still a future option, but for now the work is done.

Final image of the front. The farthest trunk on the right really bothers me. At one point I was very close to ripping it out. But I will take some more time to think about that. The tallest tree is 74 cm and the slab is 80 cm long.
Thanks for reading. Don’t acquire too many forests if you value your sanity!
Nicely done! Thanks so much for sharing. Wish mine looked so good.
