Thanks to Andrejo who sent in these beautiful pictures of his rooftop garden. (Click on the pics for larger size)
This is my garden on top of the building at which I live. On 50 square meters I cultivate all sort of plants: corn, beans, salads, potato, cucumber, tomato, pumpkin, egg-plant, basil, broccoli, sage and others. The technic that I use in the garden are solely organic, I try to create fertile soil without using chemical fertilizers and cultivate plant without pesticides or herbicides.
Because it is very dry up there I use malch – hay, grass and all biowaste from the garden to cover the ground and reduce water supply in the soil.
