Environmental Benefits for Vertical Gardens
Last Updated Jan 20, 2011 · Written by Jaclyn Fitzgerald
Vertical gardens not only look great but they are extremely good for the environment, especially when they are installed in built up urban areas. Here’s what you need to know.
Vertical Gardens Save Water
One of the biggest benefits of vertical gardens is how they manage water. For starters, watering is very efficient as it is done using a drip irrigation system or a hydroponic system. Any waste water is collected at the bottom of the garden in a special tray where it is drained away. Alternatively, it can be recycled and put back on the garden. This means that practically all the water is used up by the plants and there is very little waste. There is also no runoff into stormwater systems so natural waterways are not affected by pollutants that can be found in stormwater or waste water.
Vertical Gardens Have Few Pests and Problems
As they grow vertically, many pests cannot even get to the plants. This means that you have very little problems with pests attacking your plants so you do not need to use pesticides or insecticides on your plants, saving you using chemicals. As well, air circulates well around the vertical garden and they also get plenty of sunshine, so there is much less risk of the plants suffering from mildew, fungus or disease.
Vertical Gardens Improve Air Quality
Yet another benefit of vertical gardens is that they improve the air quality of built up areas, both inside the home and outside. This is because plants are natural filters – taking carbon dioxide from the air and replacing it with much needed oxygen. They also help to filter pollutants from the air. This means that the air that you breathe is much cleaner and healthier.
Vertical Gardens Cool the Home
When they are installed on the external wall of your home, a vertical garden acts as an excellent natural insulator, making the temperature inside several degrees lower. In fact, a room with a vertical garden can be 7 to 10 degrees cooler than a room without one! This is because the plants and the garden structure itself create a barrier that the sun cannot penetrate through. They also reduce reflective heat and light. What this means is that you don’t have to turn up the air conditioning during the warmer months, so you’re saving money on your electricity bills as well as reducing your greenhouse gas emissions.
