I'm thinking strawberries!Starting from Scratch: Vertical Gardening -As a general rule, it would take 13 to 18 times more ground space to plant the same amount in a horizontal garden as you can in a vertical garden.
An excellent garden idea for growing vegetables. PVC pipe structure with potted plants (squash or cucumbers) growing on it. You can walk under to pick. Nothing on the ground to get buggy or fungus, and you control your soil.
