To create a rooftop garden you will need a flat roof space with strong underlying structure to bear the weight of plants in containers, as well as a secure perimeter wall or railing. Good drainage is also very important. Also, don’t forget to check with your local council if you need a permit for a rooftop garden.
Depending on the position of your rooftop garden you will need to pick plants and features that screen or enhance existing views. As rooftop gardens can be more exposed to elements a careful selection of weather-resistant plants is essential for your success.
Decking is an ideal way to cover the “ground” of your roof garden.
The edges of the roof garden are usually the strongest, so put your heavier planters and garden features to this zone. Underplant individual large shrubs with small perennials and dwarf bulbs to get maximum interest from your bigger pots on your rooftop garden.
