Placement of Rocks and Stones in Japanense Gardens

Rock Forms
Rocks and stones are used in Japanese gardens for a number of purposes like terracing, alpine gardens, miniature gardens, rock walls, natural gardens, sunken gardens, cascades, formal gardens, and landscapes. The positioning of the rocks depends on the style you are trying to create. You can try to use rocks of the same formation to add uniformity, or you can opt for different types to create a stratified. Japanese Gardeners regard stones as bones that form the skeleton of their gardens, an ancient tradition. Rocks need to be embedded deep into the soil, use their placement to create clefts or pockets where plants can grow! 

The Types of Rocks and Stones
If your design includes planting a miniature garden where the plants grow over or around the stone structures, porous rock is best to use. Solid rocks and hard flints are also significant to Japanese culture, which make peaks or barren crags. Tufa is a wonderfully porous rock that features a cellular composition, similar to a sponge. Plants that favor lime attach themselves to this rock with affection. The only disadvantage is that this rock will absorb smog or smoke if it is located in an industrial area. Limestone is good for rock plants as well; the best varieties will come from Derbyshire, Westmoreland, and York-Shire.
