Yiddlenet shows you how to make an herb garden from recycled plastic bottles.
From the site:
Lately I’ve been drinking SoBe Lifewater 0 Calorie after my workouts. It comes in these really cool spiral shaped bottles. The bottles are really sturdy and I’ve been trying to figure out what (other than recycling) I could do with them. I thought the first thing I’d try was an herb garden.
I live in a townhouse, and I don’t have a lot of yard. What I do have is really really shady, so I can’t get much to grow back there. I do love using fresh herbs, so this was a good solution for me.
