Bamboo dividers are a popular choice for courtyard gardens. They provide a natural and rustic look, while also serving as a functional way to separate different areas of the garden. Bamboo is a fast-growing plant that can easily be shaped into dividers, making it an eco-friendly option. The tall and slender stalks of bamboo create a sense of privacy and enclosure, while still allowing light and air to pass through. Additionally, the swaying movement of bamboo in the wind adds a soothing and calming element to the garden.
