Vertical gardens

I actually like the idea. It is both decorative and can help introduce some green in an otherwise concrete jungle.

Its a good concept. It make maximum utilization of the available spaces. But I feel that people needs to be more creative in adopting vertical gardens as they have limited choice of plants that they can grow.

I like the idea of vertical garden and it is a quite good idea for commercial places where there is space constraint. It adds aesthetic value too to the place and they have enough resources to maintain it. For home, I find it good if you have a place to do so without interfering with the practicality of the place and then you should be on your toes to maintain it. Otherwise it becomes a mess. And also I feel that we have a limited plants and mostly ornamental ones which will thrive well in a vertical arrangement and space constraint.

I have less space on my terrace and so I have opted for steps made out of iron to accommodate more pots and also for easier maintenance as it is easy to clean in the lower spaces. 

Many hotels and apartment blocks are adapting to this because it gives enough green cover without demanding space.

It's a wonderful space economical concept ideal for urban cities with minimal living space. It will work out for enthusiasts and for those with keen interest and time for managing it.

It is good, but awareness & cost are important parameters to become acquainted with it.
