As apartments become smaller and cities busier, growing greenery in homes and urban spaces has become a popular trend. It’s a clever option for urban dwellers who are strapped for space, yet want to incorporate a natural landscape into their home in an eco-friendly way. Attached to either an internal or external wall, green walls support plants that are grown vertically and combine a number of plants to cover a wall, rather than relying on a few large plants to spread upwards. Adopt the trend in your own home in three simple steps.

1. Choose a Location

Green walls are a space saving solution that adds character to a dull wall. To install a vertical garden, it’s important to consider both the position of the wall and the watering system. Your green wall should be installed in a well-lit area or a north-facing wall, where the plants can get adequate sun. If this isn’t possible, consider setting up synthetic UV lighting in an indoor area.

Another factor to keep in mind is the durability of the wall and its resistance to water. Make sure that the wall is strong enough to hold the weight of the plants, soil and irrigation — timber or steel reinforcements may be required. For efficient water protection, apply a waterproof paint that will act as a barrier.

For an inexpensive substitute, opt for a vertical pallet garden, which will support and display potted plants. For a quick and easy solution, fasten terracotta pots with steel clamps or angle drive hooks.

2. Plant selection 

The plants you choose for your green wall will be dependent on the position of the wall. For an outdoor space, choose plants that can withstand exposure to strong winds and for low light areas, choose shade tolerant plants. Remember to choose plants with shallow root systems, as green walls have restricted soil space.

3. Water management system 
One of the biggest advantages of a green wall is the sustainable water management system and its ability to collect and pump all waste water back into the irrigation system. What’s more — minimal irrigation is required to maintain a green wall. The main types of irrigation systems for a green wall include:
• Gravity drip irrigation —  A conventional drip maximises the water used by irrigating the top tier of plants on your green wall.
• Pipe networks — Water is released from a pipe network throughout the wall at specific intervals with a timer, to ensure plenty of water is provided.
• Green walls with in-built watering networks — Contain drip heads and irrigation units installed within the framework, so it is easier to retain and water your green wall.
Along with decorative and eco-friendly benefits, vertical gardens can improve the quality of your indoor air, as plants are natural filters and will help purify the air from odours. Growing plants on your wall also adds an insulating layer as it blocks the sunlight and helps cool the home in the warmer seasons.
