Create a functional and space-saving herb garden by repurposing old bicycle wheels. Hang the wheels horizontally on a wall or fence, and fill the spokes with small pots or containers of your favorite herbs. This vertical herb garden allows you to grow a variety of herbs in a compact area, making it ideal for small gardens or balconies. Choose herbs like basil, rosemary, thyme, and mint for their culinary uses and aromatic scents. Not only does this garden idea provide easy access to fresh herbs for cooking, but it also adds a unique and charming element to your outdoor space.
