Why is maximizing space a benefit of vertical gardening?

Maximizing space in vertical gardening primarily allows for more plants to be grown in a limited area. Vertical gardening makes use of upward growth by utilizing walls, trellises, or towers, which means that rather than spreading out horizontally, plants can thrive in a three-dimensional space. This is particularly advantageous for urban environments or areas with limited ground space, as it enables the gardener to effectively increase plant density without requiring additional land area. By vertically arranging plants, gardeners can cultivate a greater variety of flora, which can also lead to a more diverse harvest and enhance the aesthetic appeal of the space. This capacity to grow more plants in a confined footprint is a primary reason why vertical gardening has gained popularity among horticulturists and urban gardeners alike.
