Transform your antique wheelbarrow into a mini water garden oasis. Line the wheelbarrow with a waterproof liner and fill it with water. Add floating aquatic plants like water lilies, water hyacinths, and lotus flowers. You can also include small fish or colorful pebbles to enhance the visual appeal. This garden idea brings a sense of tranquility and serenity to your outdoor space, creating a peaceful retreat. The wheelbarrow adds a unique touch to your water garden, making it a focal point in your garden design.
