Last spring I built an herb spiral in my backyard as an extension to my medicinal garden. I wrote a blog post about it with instructions for building your own, plus photos of my process.
A few days ago, I had a great question about sheet mulching in regards to my herb spiral. Check out Alison's question and my response in my original Herb Spiral blog post: http://www.dailyharvestdesigns.com/blog/2015/3/26/herb-spirals. She also asked how my herb spiral is doing one year later.
Here are some photos of my herb spiral today. Enjoy!
