Interesting. Per the nature of the slab/rock/etc. planting, do you then perform all individual pocket removal/replacements at the same time as a ‘1-time-event-repot’ until the next repot?
Speaking of shifting sands, my first thought was the black sand common on some of the Hawaiian beaches. Might pair nicely with this rock planting, Along with your choice of imprints or rake marks. I sense a new tool in the works. Beautiful work Sergio.
Lots of options present. My other thought perhaps " Old School " was a thicker natural slab with bark edge to complement the stone. In this case with a portion carved to accept part of the smaller base of the rock. To unify the look as done for the viewing stones. Combination of suggestions from Bonsai Techniques II , John Naka, pg 353 and 363.
That would be a nice touch, Frank!
Total beginner Sergio, but to me, a bigger suiban would be the right choice. With both of its edges slightly aligned proportionally with the edges of the canopy as the elongated illustration you provided above.
I’m only just learning about harmony and balance and aesthetics with recently acquiring books but I think intuitively, asymmetry is the way to go here. Especially since your trunks move to the right as with their collective canopy, the negative space to the right with composition over the edge at left is a winner in my eyes.
