Create a peaceful and serene Zen garden by using an old ladder as a screen with hanging plants. Choose plants with a calming and soothing effect, such as bamboo, ferns, and peace lilies, to hang from the ladder's rungs. The ladder will add a vertical element to the garden, creating a sense of balance and harmony. Pair the hanging plants with smooth stones, a small water feature, and minimalist garden decor to complete the Zen aesthetic. The Zen garden is perfect for those who want to create a tranquil and meditative outdoor space.
