What are rooftop gardens and why are they being built?
Rooftop gardens are a large-scale greening initiative that aims to bring balance to an urban environment by reaping the benefits of the vertical garden.
By providing green space on rooftops, these gardens can create more natural air quality and increase productivity in urban spaces, developing a positive feedback loop.
In addition to the positive effect on the environment, rooftop gardens have also generated positive effects on the economy. By developing green programs, cities can generate economic stimulus and development.
Various benefits can be harvested from a rooftop garden. One of the key benefits is that rooftops are able to provide urban dwellers with fresh, healthy food that otherwise might take them quite a distance to travel to acquire themselves.
A rooftop garden is not only an experimentation, but also a complete work. There are different types of garden plans and styles from which you can make a choice: whether it is the modern style or the traditional style, every plan has been elaborated with great care.
It’s really up to you how much time and resources you want to invest in your garden plan and what kind of result you are going for.
What are the benefits of a Rooftop Garden?
The first obvious benefit of roof top gardens is to grow food for sustainability. The food grown, especially in large scale, could be used for local consumption and also for trade or barter.
If flowers are grown, then this provides a positive environment in a city where people are accustomed to having a lack of green areas.
Fresh, healthy food is more likely to be consumed and this can also result in lower levels of greenhouse gas emissions – an unfortunate by-product of transporting foods over long distances.
Therefore, with the latter benefit being an important issue for many towns and cities throughout the world, it can have a large impact on the environment.
Aside from providing food for residents, these gardens could also provide a hobby or a new type of business.
Many rooftop gardeners sell their produce at a local farmers market, or sell their produce to local shops and restaurants.
With the large demographics of people living in cities, gardening has become a serious business and in times of shortage roof gardens can supply the local population with fresh, healthy and organic food.
Combined with the benefits of providing a source of food, this also acts as a way to promote entrepreneurship and development in depressed areas. Rooftop gardeners can serve as an example for other urban dwellers to follow when it comes to small-scale business and entrepreneurship.
How do I start a rooftop garden?

What plants are best for rooftop gardens?
Any plants suitable for your geography and preferable low maintenance. Cacti need very little water and can be overwintered in cold climates with temperatures below about 40 degrees Fahrenheit.
The large size of some cacti (ranging up to 5 feet tall or more) and the non-attractive appearance of many cacti make them easy to overlook.
