Having never done any sort of bonsai I recently pruned, wired and planted a small 5 tree forest from Dwarf Alberta Spruce trees from a nursery. I have been watching and reading as much as I can to learn what to do as a beginner. I realize I still need to do additional cleanup work and pruning. I have planted this in a training pot and feel like I should add maybe additional smaller trees to fill in some space? My ultimate plan was to let the forest grow for at least a year before doing anything else. Any suggestions and/or feedback is welcome. Attached are some photos before, during and after.
