PREVIOUS PAGE: A Japanese holly hedge did not age well by this courtyard in the Seattle Japanese Garden. In early 2018, it was replaced by a traditional teppo gaki bamboo fence, which provides a more effective enclosure.

When plants become too competitive or weedy, you’ll need to make thoughtful decisions about which ones to restrict or eliminate. Here in the Pacific Northwest, dry summers exacerbate the issue of shade under large decidu- ous trees and shrubs. Many of your original plants may not survive, and you may need to replace them with spring ephemerals, early-blooming bulbs, and perennials that are summer-dormant. As time passes, consider whether your origi- nal design is being realized. If it’s not, and your design does not seem salvageable, think about the possibility of a new balance of plant species— or an entirely new vision. Time in the Seattle Japanese Garden Additional strategies to address the effects of time are commonly used in Japanese-style gardens. Trees and shrubs are pruned in traditional shapes to maintain a size in balance with the garden’s other plants and design elements. Pruning is also used to highlight the attractiveness of seasonal changes and the powerful branching architec- ture that many trees develop over time. Plants that no longer fulfill their role in the garden’s design are replaced, sometimes by hardscape instead of other plants. Wooden support posts help extend the life of declining woody plants, but eventually the plants will die and be removed. With time, even healthy trees and shrubs—grown so large that scale and proportion are lost—may be cut down. Occasionally a garden develops a positive life of its own, even though its original design has been lost or obscured. Kyoto’s Saiho-ji temple garden, overtaken by moss after decades without maintenance, became a uniquely beautiful “moss garden” renowned throughout the world. The photo on page 7, of our Seattle garden’s roji (teahouse garden) illustrates how beautifully moss spreads under favorable conditions. If a similar process occurs in your garden, why not embrace it? As a docent of the Seattle Japanese Garden, I share with visitors a public garden with a decades-long time frame. Next time you visit, try to observe how the gardeners have responded to the challenges of passing time and maintain a garden that celebrates this natural process. You may find their strategies useful for preserving the resilience and longevity of your own garden. m References Thorpe, Patricia. “Growing Pains: Time and Change in the Garden.” Boston, MA: Harcourt, 1994.
