delhi metro vertical garden-min
First it was Bengaluru, followed by Kochi and now Delhi who have used the gigantic pillars on which elevated metro line runs, to grow vertical gardens. Though in Bengaluru the exercise came under lot of criticism for the way it was maintained, in case of Delhi Metro vertical gardens have transformed the look of Nizamuddin Bridge. The dull grey colored concrete pillars have now got a green cover.
Presently, Delhi Metro has experimented the vertical gardens on eight pillars of the elevated Blue Line (Dwarka Sector 21-Vaishali/ Noida City Centre) between Mandi House and Pragati Maidan stations. DMRC will, in future, explore the possibility of replicating this experiment at other locations also.
Growing vertical garden on pillars is a simple technology – the pillars are first covered with a mesh like frame on which small pots with plants are mounted. These potted plants are grown in closely fitted rows which eventually covered the entire pillar when they grew up. These are evergreen plants that remain green throughout the year and also require minimal maintenance. These plants are watered regularly through spraying machines with the help of pumps.
