How about a vertical garden?
As mentioned in my post about container gardening, I’m trying to get some greenery happening around my place, but I don’t have much space. I've seen a few vertical gardens around town. There's one at the MCG out on one of the terrace bars on the 4th level which looks awesome. I'd love to do a hanging herb garden or something. I'm wondering how they work? I found this video about vertical gardening and was wondering if anyone has had any experience with them?
