The first option for rooftop gardening is container gardening, a less formal, highly flexible, cheaper form of roof gardening which is commonly seen in cities worldwide. In container gardening, few to no modifications are made to the existing roof structure; containers – anything from plastic swimming pools to recycled-wood planters – are placed on a rooftop and filled with the desired soil type and plants. One of the problems here is the soil in rooftop containers might thaw on a warm winter day. Further roof container gardens dry out quickly and often require daily watering unless a mulch cover such as straw, wood chips or even a sub-soil layer of newspapers and compost is used to slow down evaporation. Also, in places with extreme climate, the container material must be carefully considered. | The first option for rooftop gardening is container gardening, a less formal, highly flexible, cheaper form of roof gardening which is commonly seen in cities worldwide.

* Hydroponics is found to be way too complex and expensive in lot of eastern countries and some of african countries too. In these places, roof gardens build out of local materials are most suitable. They are repair and maintained by the communities themselves. This is seen in places like India, St. Petersburg and Senegal. Infact, in Senegal people have devised a local solution using bricks and wooden box beds. In India too, the use of locally available cheap materials to create roof gardens is most successful. The “Doshi System” is offered as the most suitable method. It uses sugarcane stalks, collected from sugarcane juice vendors outside of his house, as biomass.
