DIY Rooftop Garden
If you are a city dweller or even if you live in the suburbs or small town USA, you might think all hope for a productive vegetable garden is lost. Nothing could be further from the truth. Fortunately, we have plenty of room for a garden; BUT I am originally from New York and know plenty of people who don’t. This article is the most comprehensive I have seen. It discusses everything from design, to structural considerations to how to plant the garden itself.
