Create a unique trellis for your climbing plants using bicycle wheels. Attach the wheels to a sturdy frame or fence and train your plants to grow along the spokes and rims. As the plants grow, they will create a beautiful and intricate pattern on the trellis, adding visual interest to your garden. This garden idea is perfect for vine plants like morning glories, clematis, or sweet peas. The bicycle wheels provide a sturdy support system for the plants while adding a touch of whimsy to your garden design.
