You may have heard about green walls or even seen a few. Also called living walls, live walls, eco-walls and vertical gardens, these structures are essentially walls covered in vertically grown plants, and they can appear either inside or outside. The idea has been around for a while, and it’s really caught on lately due to their environmental and health benefits, as well as appealing aesthetics. But not all green walls are made equal. Read on to learn how a green wall should be designed in order to be useful and friendly to the environment.
How Do They Work?
There are several types of green walls. Some might consider regular walls covered in ivy as a green wall, while others would limit the definition to walls specifically designed to hold vegetation.
The latter type can be constructed in various ways. They might consist of panels with pre-planted vegetation, or replaceable trays that fit into slots in the wall, enabling easy removal if necessary.
Vertical gardens also vary in terms of how they function. The simpler models require hand watering, while others have self-watering pipe systems. Many green walls rely on hydroponic systems that use drip irrigation.
Based on the desired aesthetics and effects, you might choose different types of plants. You can include many varieties of plants, including groundcover, ferns, shrubs, flowers and more.
Green walls have become popular in urban areas where people want to make their space greener but don’t have a lot of room to do so. Vertical gardens ensure the benefits of green space without taking up too much space.
