Definition - What does Vertical Garden mean?
A vertical garden is a garden that grows upward (vertically) using a trellis or other support system, rather than on the ground (horizontally).
Anything grown on a trellis or even a fence is technically part of a vertical garden. This technique can be used to create living screens between different areas, providing privacy for your yard or home.
More recently, vertical gardens can also be used to grow flowers and even vegetables.
MaximumYield explains Vertical Garden
Vertical gardening is used by many as a means to ensure they are using their garden space to its maximum potential. A simple structure formed by bamboo poles can allow bean plants to climb vertically, providing more growing space than would be possible in a conventional horizontal garden. Cucumbers, squash, and even tomatoes can be grown vertically, as well.
Climbing plants and vines are far from the only options when it comes to vertical gardening. With a little planning and the right materials, vertical gardens can be created that allow you to grow virtually anything. A number of DIY kits can be found that use small cups or other containers set in rows in the face of a vertical support. These containers are filled with soil and seeds, and then watered.
Of course, you’re not limited to using a single row of containers set into a vertical surface. You can also use virtually any system that allows you to grow upward instead of outward. This includes scaffolding, shelving systems, and more. Simply create flat surfaces at varying intervals along the vertical axis and add plant trays or pots.
Harvesting crops from a vertical garden is significantly easier than with a conventional on-the-ground garden. Because you are able to harvest while standing mostly upright or completely upright (depending on the vertical level being harvested), as opposed to kneeling or squatting on the ground, vertical gardening is easier on the back and legs, and many people with arthritis or other disabilities find it highly beneficial.
