Transform recycled tin cans into a hanging herb garden. Paint the cans in vibrant colors or leave them as they are for a rustic look. Attach a sturdy rope or wire to each can and hang them from a pergola, fence, or balcony railing. Plant herbs like thyme, parsley, and cilantro in each can, ensuring they receive enough sunlight and water. This hanging tin can herb garden not only adds greenery to your space but also saves valuable floor or counter space.
