If you like gardening and recycling, I am sure you are always looking for new creative ways to combine the two.
Here's an awesome tip for you: use wine bottles as borders and edges: this looks nice and is 100% eco-friendly. They can be arranged in a pretty way and they will never get old: will last as long as they want to keep them in the garden.
You may enroll you whole neighborhood into collecting the bottles. This should be fun!
