On the first time that I had seen a vertical garden I thought the design was a real garden that is erect and not flat on the ground. It was in the middle of the busiest avenue here so I had no chance to inspect it. On the second time I saw another vertical garden I did not hesitate to check on it. Now I know that the vertical garden is a platform to hold the plastic pots where the flowering plants are planted.
For those with no space for a real garden maybe you can turn to the vertical garden. If you are not keen on having ornamental plants then plant vegetables so you will have some edibles on your vertical garden.
Do you clean your garden regularly?
