Add a touch of elegance and privacy to your courtyard walled garden by hanging curtains or drapes. Install curtain rods or wires along the walls of your garden and hang lightweight, weather-resistant curtains or drapes. Choose fabrics that complement the style of your outdoor space, such as sheer white curtains for a romantic look or vibrant colored drapes for a bold statement. The curtains not only provide privacy but also create a cozy and intimate atmosphere in your garden. You can easily open or close them depending on your preference, allowing you to control the level of privacy and sunlight in your outdoor space.
