When looking at Japanese gardens, whether old or new, traditional or modern, I often notice the beauty of black soil in Japanese gardens.

In European gardens, you rarely see bare soil except during winter and early spring. Soon, the first bulbs sprout, followed by perennials that cover the ground in green.

However, when creating a Japanese garden, it helps to change your idea of how a flower bed should look. Black soil can be appealing, offering contrast that highlights flowers and shrubs beautifully.

For example, the Botanical Garden of Hamburg (Loki-Schmidt-Garten) has a place called “Perennial Valley.” Although not Japanese, it uses visible black soil along a small artificial river, echoing Japanese design ideas.

Black Soil in Traditional Garden Types

Look closely at courtyard gardens (tsuboniwa) and tea gardens (chatei or roji). Many have moss, but in areas where moss is hard to grow, you often see black soil instead.

In modern tsuboniwa, gravel appears more often, but traditionally, plants were carefully chosen and placed with features like stone lanterns. Courtyard gardens served a climate-regulating purpose for the house, so the ground was often not visible from inside.

Tea gardens, or roji, guide guests to a tea ceremony. Their stepping stones, water basins (tsukubai), and shrubs create an atmosphere of wabi-sabi. Where moss will not grow, black soil often fills the spaces.

Cost and Maintenance Considerations

Today, low-maintenance trends lead many to use gravel and weed-proof sheets. Yet gravel discolors, collects leaves, and eventually allows weeds to grow. Adding rocks and plants increases cost and upkeep.

In Japan, planting trees and shrubs with soil between them makes weed control easier. A simple string trimmer a few times a year keeps costs low. European-style dense planting has also become popular, though it often needs a gardener for yearly maintenance.

What looks best is a matter of taste. Still, consider black soil as part of your garden design—it is both traditional and practical.

Garden Plants of Japan

Japanese plants have had an unmistakable influence on the gardens of the world. Who can imagine gardens without flowering cherries, hostas, Japanese maples, or magnolias? For all the popularity of these plants in international gardens, however, few gardeners know the full story of Japanese plants — their history and uses in gardens in Japan.
