Vertical gardening is a method of growing plants in an upward direction, rather than spreading out horizontally. This technique utilizes structures like walls, trellises, or specially designed planters to support plants, making it ideal for small spaces such as balconies or urban environments. It allows for efficient use of space and can enhance the aesthetic appeal of an area. This gardening style can accommodate a variety of plants, including herbs, flowers, and vegetables. Vertical gardens can also improve air quality and provide insulation for buildings. They are often seen in green architecture and urban landscaping projects, promoting sustainability and biodiversity.
