Not to be confused with a green roof, I am interested in putting together a rooftop garden in the city. I have no idea where to begin. Any tips?
Well, as with most gardening queries, the best place to begin is to do some research on rooftop gardens. Find what will grow in your climate (I like to use native plants, if possible) and what you're looking for: annual v. perennial, short & bushy vs. tall, red v. blue, etc. Note what kind of light and how much our roof gets in a typically day and during each season. I'm sure there are more info sources just on the internet everyday. Good luck!
