Many buildings are literally going green. The addition of a vertical garden, whether interior or exterior, has many benefits.

The benefits of gardening are numerous, but gardening also requires land – something that many commercial and urban settings lack. However, vertical gardening is a fairly simple way to enjoy the aesthetics of plants within a limited space. Vertical gardens grow upward alongside building exteriors and interior walls, creating captivating scenery where it would otherwise be impossible.

Vertical gardens, or green walls, feature living plants. The design and purpose of vertical gardens run the gamut – from elaborate designs that scale towering buildings and are installed simply for aesthetics to smaller gardens that are intended to provide locally grown food for the surrounding community.

Benefits

The benefits of vertical gardening are abundant. A vertical garden can substantially reduce a building's energy demands by providing increased shade and insulation, and reduces the need for maintenance, as it provides a shield of sorts from exposure to the elements. In addition to shielding a building from inclement weather, the plants of a vertical garden alleviate sound pollution and Urban Heat Island Effect (increased heat within urban areas due to land modification and the use of materials that retain heat), according toUrban Habitat Chicago, an urban agriculture design and education firm. The introduction of plants on a large enough scale can improve the air quality of the surrounding community. Vertical gardens also increase local biodiversity and improve the morale of those who live, work, and play in the community.

Vertical gardens can also help to stimulate secondary and tertiary economies, according to Urban Habitat Chicago. In addition to the people who must be hired to design, install, and maintain the gardens, funds can be generated from harvesting and selling locally grown food from the garden or that food can feed people within the community.

How Are Vertical Gardens Structured?

Not every space is suitable for a vertical garden. At a minimum, the space—both interior and exterior—should have an internal irrigation system, good drainage, access for regular maintenance, and an adequate support structure, according to Urban Habitat Chicago. Plants can be grown between layers of cloth and stapled in place on sheets of expanded PVC, according toPatrick Blanc, the French botanist and author responsible for popularizing the idea of green walls and vertical gardens. Once installed, hydroponics can be used to feed the plants.

Interior vertical gardens require a little extra care, as supplemental lighting may be needed to simulate sunlight, and proper ventilation is required to ensure the steady growth of healthy plants. The interior wall should also be waterproofed, and extra care must be taken to keep the surrounding floors, walls, and ceiling dry.

Finding a Location

查找合适的地方的垂直花园是相当简单的,只要空间是否满足上述标准。室内垂直花园是非常适合酒店和公司大厅,以及餐厅和零售商店。室内垂直花园,也可以为那些谁可能无法外出频繁,如人住在医院和养老院提供与自然的统一感。办公室和学校建筑也用于室内垂直花园的理想地点。

Since maintenance of exterior vertical gardens is a little easier, the ideal locations for exterior vertical gardens are many. Basically any vertical space that could use a little face-lift (and receives adequate sunlight) can benefit from the installation of a vertical garden.

The cost of a commercial exterior vertical garden generally ranges from $60–$160 per square foot, according to Urban Habitat Chicago. This cost includes the plants, internal irrigation, and installation but does not include associated maintenance costs. Internal vertical gardens are usually more costly, due to the need to waterproof the area and to design a system that will not damage the surrounding interior spaces. For both interior and exterior vertical gardens, the more elaborate the system and the design, the higher the cost.

Vertical Gardening Challenges

A few factors can make vertical gardening challenging. Finding adequate sunlight for exterior walls may sound simple, but different plants need varying amounts of sunlight. After selecting a wall, much consideration should be given to the types of vegetation that will work best together, on that particular wall. Additionally, hosing down plants will likely just moisten the plants, with the majority running off onto the ground, so an irrigation system must be used for optimum results. Irrigation systems with time-released fertilizer can help to give plants a boost and reduce maintenance. Although vertical gardening, just like traditional gardening, can be challenging, with proper installation and maintenance vertical gardens can thrive.
