Vertical garden systems differ greatly in the way that they are erected. Some will require wall for support as the hanging garden will tend to pull back due to built in flexibility. Other can be attached to posts or stands without this problem.
Some systems are modular, you can add in just about any direction seamlessly, others are a stand alone system that do not lend themselves readily to expansion.
Some systems are only suited to hand watering, other have built in drip irrigation systems that take the worry out of watering, however they usually cost more.John Allman
