I love to see gardeners use recycled tires because they cause so much waste other wise, did you know you can stack them up very tall to grow a massive amount of potatoes in a small area. I did it years back, you start with one tire fill with straw and hay and a little soil then plant potatoes and keep adding more tires and soil/hay on top as it grows .
I like your ColorChallenge post. I enjoy learning about new people and different cultures.
Any way if you and anyone reading this would like to see my #colorchallenge post

We have grown potatoes like that in tires. It does work great and yields a lot!! I'm glad you appreciate the joy's of using those discarded tires. Reusing, repurposing, recycling, upcycling is one of our fortes at the @gardenofeden. Sustainability is where it's at!!! Thanks for your comment @isteemithard.
