What is a Japanese rock garden?
A Japanese rock garden, or karesansui (“dry landscape”), is a stylised miniature landscape of rocks and raked gravel in which the gravel stands for water. Straight lines and waves suggest flowing water; concentric ripples around the rocks suggest islands in the sea. It is not walked through but viewed from one fixed position, often a veranda. In the West it is usually called a Zen garden, and it has little to do with an alpine rockery full of plants.
The classic dry gardens were created at Zen Buddhist temples in Kyoto during the Muromachi period (1336-1573). The best-known example is the garden of Ryōan-ji (late 15th century): fifteen stones in five groups set in a rectangle of white gravel, with moss around the stones as the only vegetation.
Design principles
- Stones are rarely placed in straight lines or symmetrically; groups of three are common.
- More horizontal than vertical stones, a rule from the old Japanese garden manual Sakuteiki.
- Stones that vary in shape, colour and size, but no bright colours.
- Angular gravel holds raked patterns far better than rounded gravel or sand.
Application
- Use crushed, angular gravel. Rounded pea gravel rolls and will not keep a pattern. Kyoto gardens traditionally use crushed granite.
- Lay a weed membrane underneath. It slows weeds and stops the gravel sinking into the soil, while letting rainwater soak through.
- Fit a firm edge. A kerb or steel edging keeps the gravel in place and the outline crisp.
- Bury large stones partly. A stone sitting on the surface looks dropped there; partly buried, it looks as if it grows from the ground. Move heavy stones with help or lifting gear.
- Plan for upkeep. Leaves and weeds spoil the effect quickly, so rake and clear regularly.
Common mistake: filling a small space with too many rocks, ornaments and plants. A rock garden works through emptiness and restraint.
