@Cadillactaste , Being in the northeast, I rarely see porous lava rock like your planting shown. Im curious if you found wild or purchased. I started this past spring with making my own rock formations with cement and mixing with various substrates. I got a few that I am gonna let get weathered for winter and plant next spring, plus still working the trees, haha...patience and timing = better bonsai creations, as I am learning each season.
