Add a touch of whimsy to your flower beds by using old bicycle wheels as edging. Place the wheels horizontally along the border of your flower beds, burying them partially in the soil. The circular shape of the wheels creates a visually interesting edge, while also preventing grass or weeds from encroaching on your flower beds. This garden idea adds a charming and rustic appeal to your outdoor space, giving your flower beds a unique and eye-catching border. Consider painting the wheels in vibrant colors to further enhance the visual impact.
