Vertical gardening is for gardeners who do not have a lot of horizontal space. It has become a niche science these days with many elaborate and quite amazing systems, often involving hydroponics and engineered structures that cover whole walls several stories high.
It is well worth researching carefully what is the most useful system for elevational planting in the city. The flexibility of what is available means the system chosen can be matched ideally to the space available. A good garden frame system will last for years and can be stored away during winter months for assembly again in the spring.
