Create a peaceful and tranquil Zen garden with a rustic wooden arbor as the centerpiece. The simplicity and natural beauty of the arbor complement the Zen philosophy of balance and harmony. Surround the arbor with gravel or sand to create a calming ground cover. Add a water feature such as a small pond or a bamboo fountain to enhance the Zen atmosphere. Incorporate minimalist elements like stone lanterns and bonsai trees to complete the Zen garden design. This garden design is perfect for those who seek a serene and meditative outdoor space.
