Wooden planters are a versatile option for dividing a courtyard garden with ornamental grasses. They can be used to create raised beds or freestanding planters that act as natural dividers. Wooden planters can be customized in terms of size, shape, and design to suit the specific needs and style of the courtyard. Ornamental grasses can be planted in the planters, providing a lush and green screen that adds privacy and visual interest to the space. Wooden planters also add a warm and organic feel to the courtyard, enhancing its overall aesthetic.
