Creating a fragrance garden in an outdoor plant box is a delightful way to enjoy aromatic plants in small spaces. Start by selecting a sturdy, well-draining plant box made of wood or another durable material. Choose a mix of fragrant flowers like lavender, jasmine, and roses, along with herbs such as mint, thyme, and basil for a layered scent experience. Arrange taller plants at the back and shorter ones in front for visual appeal. Ensure the box receives adequate sunlight and water regularly. Add mulch to retain moisture and enhance the garden’s aesthetic. With careful planning, your outdoor plant box will become a fragrant oasis.
