The Importance of Irrigation for Green Walls
No matter where in a building you install green living walls, you need to think about how you will look after your plant species for them to continue to grow and thrive. Compared to a traditional horizontal garden, living walls have their own set of challenges and environmental conditions, such as limited root space and varied amounts of exposure to sunlight. Due to these factors, you need to ensure you have an irrigation system in place that will provide a consistent moisture supply. As the plants in green walls usually have very limited space for their roots, this means they are more likely to struggle with fluctuations in their moisture levels. Consistent irrigation ensures that you avoid both drought or waterlogging, both of which can cause damage to the plants.
Irrigation systems don’t just focus on delivering water to the plants, as they also provide nutrients to plants when needed. This is particularly important for green walls, where the nutrient supply can be limited by the design of the wall and the confined nature of the design. When you install an irrigation system, you’ll notice that less time and effort is required for the maintenance of your green wall. Even when you are busy with work and life, your green wall will receive the care it needs. Proper irrigation helps to reduce stress for your plants and keep your living wall looking attractive and healthy for as long as possible.
Types of Irrigation Systems for Green Walls
Selecting the right irrigation system for your green wall depends on factors such as the type of green wall you’ve installed, plant species, and the specific requirements of the installation. These are a few of the best irrigation systems which can easily be added to most green walls.
Drip Irrigation
Drip irrigation is one of the most popular systems for green walls. It uses a network of tubing and emitters to deliver a precise amount of water directly to the plant roots. It’s a very efficient solution for green walls and reduces evaporation and runoff. You’ll have more control over water delivery, which can help with managing a variety of plant species and their unique water needs. Drip irrigation systems can be adapted to fit any type of green wall design and size, but you will find that they need regular maintenance and cleaning to ensure the system keeps working properly. It can be quite an expensive initial investment, but is a long-term solution that will keep your green wall in top condition.
Misting Systems
Fine sprays of water provide moisture to your plants when you install a misting system. This system is a good option for creating a humid microclimate within your green wall and helps tropical plants and mosses to thrive. Misting systems are designed to provide even coverage for your plant foliage and will ensure that all of the plants on the wall receive some moisture. Water waste is one of the biggest drawbacks of this type of system, as misting systems can result in some evaporation and drift. You’ll also find it’s not as effective for deep-rooted plants as the mist may not reach their root zone.
Capillary Matting
Capillary matting involves placing a water-absorbent mat under the green wall structure. This draws water up to the plants through capillary action and ensures that water is evenly distributed across your green wall. It’s a very low-maintenance option after its initial installation, making it ideal for green walls within workplaces and busy family homes. This type of irrigation system won’t be suitable for all types of green walls, especially if you have a vertical or complex design. After some time, the matting might start to degrade and will need replacing.
Effective irrigation is critical to keep the plants in your green wall looking their best. By choosing one of the most effective irrigation systems we’ve shared above you can ensure you enjoy optimal plant health, aesthetics, and environmental benefits.
