Without proper maintenance, a dead green wall ensures your façade looks like something out of a horror film, with withered, brown vegetation screaming NEGLECT! 

Despite setbacks, the popularity of green walls continues to grow. Once considered a luxury feature for upscale hotels and private residences, they are now being integrated widely into public and commercial spaces. 

In Sydney, One Central Park, is one of the most impressive examples of a successful green wall. At the time of completion, it was the highest green wall in the world, spanning 150 metres. It uses 250 species of Australian flowers and plants and was designed by botanist Dr. Patrick Blanc, using his Le Mur Vegetal system. 

Ok, but this is a special case.

Maintenance is a persistent problem for buildings that aren’t as advanced as One Central Park. Without proper care, green walls can quickly deteriorate, as I’m sure you have seen around the city you live in. 

As Australia embraces greener urban landscapes, the lessons learned from both successes and failures of green walls will play an important role in shaping how we green our cities.

So, what do you think, should we persist with living green walls?
