Greenwall Vertical Garden 


Vertical gardens, otherwise known as green walls, refer to vertical structures with living plants attached to them. This modern landscape design not only gives your walls a naturally artistic and aesthetic look, it also provides a calming atmosphere, filters pollutants in the surrounding air, and typically features built-in irrigation systems – no wonder it has become increasingly trendy over the years!


Benefits and functions of vertical gardens

Besides visual appeal, vertical gardens also provide a myriad of practical benefits. Firstly, green walls add a touch of nature to our urban city, which can help reduce stress and fatigue. If you’re revamping your office area, this would be something you might want to look out for to liven up your workplace and boost your employees’ productivity. 

As the large amount of plants can purify the air effectively and naturally, this enhanced air circulation can help improve alertness and cognitive abilities as well. With a sufficient amount of plant matter, noise levels can be lowered too.

Furthermore, outdoor green walls have been found to be energy-efficient and cost-effective. The plants on the walls reduce both the overall temperature of the buildings, and their transpiration process slightly lowers the indoor temperature. Placed outdoors, these plants also redirect water away from the walls during rainfall and provide protection from UV rays.

By using green walls, you can reap the benefits of enjoying plants and greenery around your area without compromising on the space on the floor. Green walls can also be easier to maintain than regular gardens, as there’s no need to hire a gardener to take care of overgrown plants weekly. 


Types of green walls

To tailor to your needs and environment, you can choose from different types of green walls made of a range of plants, materials and designs.

For example, outdoor green walls and indoor green walls have different benefits. Outdoor green walls help save costs as the outdoor plants can reduce the building’s overall temperature, while indoor green walls are easier to maintain. However, the sizes of indoor green walls will be more limited to fit the constraints of your space. 

The plants used for indoor and outdoor walls will be different too, as some plants prefer full sun while others prefer full shade, and some require abundant water while others only need a little. You can also choose climbing plants to create climbing facades – frames such as trellises will be used to support the plants and encourage direction of their growth.

In terms of shape and materials, living walls that are built from metal or plastic modules are usually rectangular, while those that are made of felt can be molded into round or customized shapes. For active green walls where air circulation features take priority, the walls are usually made of rectangular modules.

The type of green wall chosen affects the way it is maintained. For example, watering can be done automatically for green walls with hidden pipes, while those without may need manual watering. If you would like to enjoy the benefits of outdoor or indoor green walls with even lower maintenance, you may consider artificial vertical gardens. With no need for sunlight or watering, those walls can be placed pretty much wherever you prefer.


Vertical garden systems

There are also different types of vertical garden systems you can choose from. Vertical gardens systems refer to the combination of the plants, growth medium they are rooted into, and the structure the medium is placed on, such as boxes, bags or pots. There are generally four types of vertical garden systems – loose, mat, sheet and structural. 

Loose growth medium systems refer to those in which soil is packed into a shelf or a bag, while in mat systems, the plants are rooted directly onto the mat made of felt, and do not require loose mediums such as soil. 

Similar to mat systems, sheet media systems do not require loose mediums as well, but they use inorganic polyurethane sheets which are more durable. Lastly, structural media systems are a combination of loose and mat systems – they form a block that can be made in different shapes and sizes. 

The choice of systems affects the desired design, whether pre-growing is required or not, the type of irrigation system and level of maintenance. For example, soil-based systems allow for simple irrigation construction, which lowers installation and maintenance costs. 


Cost of vertical gardens

The cost of installing vertical gardens depends on the type of system chosen. Generally, its cost can range from $200 per square meter to $1200 per square meter.

For a cheaper option, you can opt for green walls where the plants are planted on-site, which reduces the cost of pre-growing plants elsewhere. However, that means that the walls won’t be complete upon installation, and it may take about a year before the plants start flourishing.


Maintaining vertical gardens

Vertical gardens may appear tedious to upkeep, but they are in fact generally easier to care for than regular gardens. As the plants would typically be in containers or are off the ground, the risk of fighting pests and diseases is smaller. 

To maintain them, you’ll need to perform tasks such as watering, fertilizing, and removing dried leaves and weeds – which are not too different from regular garden maintenance. These steps may even be skipped if you chose to use preserved plants and flowers instead.

For vertical gardens that have an automated watering system or automatic drip irrigation system, you can expect to spend about 1 hours a week on maintenance. If not, it would be about 2-3 hours a week. Through trial and error, you can figure out the frequency and amount you’ll need to water your plants for them to thrive. 

However, vertical gardens may require more fertilizing than normal gardens due to the small packages the plants are kept in. An outdoor vertical garden may require fertilizing about once every 3 weeks, while indoor ones may need them every two months. 

Other factors such as pruning and trimming depend on the types of plants. To find out which types of plants and vertical garden systems work best for you, consult experts who can advise you based on your location, needs and wants.
