Construct a functional and visually appealing herb spiral garden with the help of recycled wine cork bulletin boards. Use the cork boards to label each herb planted in the spiral, providing information about their growth habits, companion planting suggestions, and harvesting techniques. The cork material is resistant to rot and decay, making it suitable for outdoor use. The spiral design allows for efficient use of space and creates microclimates, enabling you to grow a wide variety of herbs in a small area. This unique garden design will be a focal point in your outdoor space.
