Rock Plantings by Master Masahiko Kimura

As a follow-on to Randall Lee’s great demonstration for creating a Juniper rock planting on September 26, 2017, I wanted to show some photographs of rock plantings by Master Bonsai Artist Masahiko Kimura of Japan. During the 8th World Bonsai Convention, April 27-30, 2017, at Saitama City, Japan, Kimura performed the first of many demonstrations by Master Bonsai Artists. He chose to demonstrate how he creates a Juniper (Juniperus chinensis ‘Shimpaku’) rock planting. Kimura builds a rock formation using Feather Rock (the landscape boulder is a porous, pumice boulder, sharp and coarse, which is much lighter than most stone). He carves out pockets at various locations and heights where he intends to plant trees. The rock formations are usually formed in a stable, upright position. After carving the rock, Kimura pours a liquid motar cement over the entire rock formation which seals it and makes handling the feather rock easier. The motar cement is colored grey to charcoal. After the motar cement is set, the planting of trees can begin. Muck (Sphagnum moss and clay soil mixture) is used to hold and grow the plant roots. Low carpets or mounds of green Moss are finally pinned in against the muck to hold it in place. Sprays of water are used to keep the plants and muck moist during application and after care.
