First it was “Green Roofs” now it is “Green Walls” or Living Walls. You can create an outdoor Green Wall on your balcony.
– a couple of trellis, anchored in a pot of dirt against one of your balcony walls. Depending on the amount of light you could grow flowering vines in the summer then plant peas in early spring.
– metal shelving or a bookcase against the wall with planters on each shelf. If your balcony is shady your “wall” can be made up of indoor plants – philodendron or other trailing plants.
– there are more sophisticated systems of hanging Green Wall “pockets” that look kind of like a magazine rack or sets of pots that can be attached to a wall in rows. You could have edible plants like herbs and lettuce which require very little soil. An internet search on green wall gardens will show you many options.
As always, weight, water and building rules remain considerations for any system attached to the wall. Ask before you invest.
Colorado State University has a residence hall with an indoor green wall. It is the Pavilion at Laurel Village. An internet search will yield a variety of stories and photos.
Send me a comment and let me know where you find other indoor or outdoor Green Walls in Denver.
