so is the netting there to prevent soil from washing away until moss grows around the soil? is that a common slab technique?
I would be in no hurry if it's taking water and you trust the soil...
Years ago I almost killed mine by over potting it. Roots just couldn't get out to the edges. Now I just try to let it be.
I think you can help the image quite a lot by just squishing the muck wall a bit. I've made a vert of flattening the wall on the right and making the left side bulge out a bit, to illustrate (jump back and forth between your orig and my virt in the image viewer). The apparent uniformity of the muck wall is what catches my attention and it remains so, for me, even if the forest is set lower.

Very nice forest, Serg. The white trunks and branches are surreal.
i just love the whiteness of the bark and how the leaves open up
