You notice something strange when you stand at the edge of a traditional Japanese garden. There is a slowing of the mind. An afternoon in the park is pleasant, but in a concrete, almost physical sense-the eye settles, the visual noise diminishes, and there is a quality of quiet that is hard to describe but immediately apparent. This isn’t a coincidence. The trees, shrubs, and gravel lines have all been positioned and shaped with an accuracy that is uncommon in Western gardening. Upon realizing how a pair of secateurs and every overgrown shrub you have ever left for another season work, your perspective changes.
Japanese pruning practices have no equivalent in European garden tradition. Western topiary, on the other hand, tends toward geometry: spheres, cones, tightly clipped rectangles of yew or box. Plants are intended to appear older, more weathered, and fundamentally themselves, as if time, wind, and the unique characteristics of the species have all worked together to form this shape. A technique called Niwaki, which translates roughly to “sculpted garden tree,” has been honed over centuries by monks, samurai, and generations of devoted gardeners whose tools were often superior to those in the West.
Niwaki, and the larger Japanese garden philosophy, are based on the concept of mono no aware, a phrase that suggests impermanence and a gentle sensitivity to passing things. This emotion is intentionally evoked in Japanese gardens. Cherry blossoms are fleeting in spring, which is one of the reasons for celebrating them. The rich red color of autumn maples is more significant because winter is right around the corner. Pruning is not maintenance in this sense. It is composition-the deliberate shaping of plants to create particular emotional effects in specific garden locations, seasons, and at specific times.
Jake Hobson is primarily responsible for bringing this tradition to the West’s attention. After graduating from the Slade School of Art in London with a degree in sculpture, he traveled to Japan for a month to see the cherry blossoms. For two years, he worked at a traditional tree nursery in Osaka, where he learned about tree training and pruning. Aside from technique, he also brought back perspective, the ability to look at a tree and ask what it is trying to be instead of what shape it should take. He introduced Japanese tripod ladders and Tobisho secateurs to a generation of British gardeners and landscape professionals who describe the tools with the reverence usually reserved for Japanese kitchen knives. Niwaki: Pruning, Training and Shaping Trees the Japanese Way, published by Timber Press, remains the definitive English book on the subject.
Niwaki’s practical mechanics revolve around a single, illuminating concept: opening the interior of a tree rather than closing it. Understanding these techniques takes time. Japanese open-center pruning, known as sukashi, removes crowded growth, crossing branches, and anything that prevents light from penetrating the plant. A graceful structural framework of deliberately spaced branches supports the canopy layers above it with a natural lightness. In person, it’s hard to describe the quality of a well-pruned niwaki tree; it’s like something between a sculpture and a living being, ancient-looking without being run-down, windswept without being disheveled. As part of the method, cascade branches are formed, trunks are curved with weights and wires to create S-curves, and pine needles are meticulously groomed to create the cloud-like foliage pads seen in pictures of Kyoto temple gardens.
A change of pace rather than a collection of cuts is perhaps the most significant benefit of niwaki for Western gardeners. In the West, most garden maintenance is based on the control principle, which involves keeping things neat, preventing plants from taking up too much space, and enforcing order on chaotic growth. Japanese pruning is completely different from Western pruning. You study the plant before making any cuts. It can be circumvented. From the perspective from which it will be viewed, you examine it. Branches that are doing something interesting can be distinguished from those that are just taking up space. When they do occur, the cuts are smaller and more deliberate than in Western maintenance pruning, and their effects take years to manifest.
There is a broader philosophy known as wabi-sabi, which is a Japanese aesthetic that appreciates age, flaws, and the marks left by time. As a result, moss-covered stones are better than clean ones, a weathered ceramic pot is more captivating than a new one, and a tree with a twisted trunk and obvious age is more appealing than a young, perfectly straight one. This is directly at odds with the Western gardening instinct for neatness and freshness, and it is worth experiencing the discomfort that results. Plants can create some of the most memorable garden moments when they are allowed to express something challenging. In Japanese culture, the bare winter silhouette of a pruned pine against a grey sky is as valuable as spring blossoms.
Observing someone working in the niwaki tradition often leads to a subtle reevaluation of what garden work entails. Instruments move cautiously. There is no urgency. We consider every cut. Most Western gardeners handle their plants differently: they solve the immediate issue of excessive growth quickly and practically, without considering how the plant might look if the issue were resolved differently. For the Japanese pruning philosophy to be applied, a Japanese garden is not necessary. Slow down, pay attention, and start cutting toward the essence of the plant rather than away from inconvenience. It is hard to reverse a change once it has been made.
