The trend of vertical gardens is growing globally. With limited area and high real estate cost plants are hardly seen in urban homes. Even if they find space in our homes they are limited to few pots and plants. Building vertical gardens is believed to be an innovative solution to stay close to greenery without compromising on horizontal space in high valued real estate in cities.
Plants are known to have a soothing effect on humans and help us stay in touch with nature and landscape. On one hand many believe that as they can be maintained better they are apt for areas with human habitation, while there are many who believe that vertical gardens are better for public spaces. Below are some of the advantages and disadvantages of having vertical gardens in residential areas.
With limited availability of horizontal space in cities, vertical gardens seem to be a perfect fit to cover depleting green zones in urban areas. It is a cost effective solution as real estate cost is negligible here. Even though the price of installing vertical gardens is currently high, but with increasing demand the price is expected to go down.
Besides its real estate feasibility, vertical gardens have many other benefits of creating such biodiversity in cities. a) reduction in urban heat island effect, b) reduction in smog, c) act as sound barrier and help in reducing sound pollution d) improve quality of air we breathe e) creates healthy eco system for living organisms like birds and insects f) makes our cities look beautiful and green g) helps in reducing dust, h) in homes the soil quality and plant quality can be maintained i) residents can easily make sure proper hydration for plants j) residents can grow vegetables and herbs for their daily use.
Vertical gardens is a flexible solution and can be installed anywhere from a blank wall or a column to patios to balconies to boundary wall to railings. Even the height of the garden can be adjusted depending on the space and convenience of the residents. These days these gardens have become more advanced and can be installed with an automated drip system for irrigation.
Now if we come to disadvantages or few things we need to be careful about while opting for vertical gardens are – a) construction of vertical gardens are financially and technologically challenging b) they require high maintenance compared to horizontal green spaces c) not all plants can be grown using this format d) limited to small plants and herbs e) one needs to be careful while choosing plant species as the ones with deep roots can affect building structure f) these plants would attract unwanted insects into residential premises g) plants will emit carbon di oxide in the night, so placement of plants needs to be planned carefully.
Vertical gardens have many positives and they are becoming a contemporary and innovative element of urban green infrastructure. Even though they cost more and require maintenance, they are still a better option than having no plants in urban spaces.
