In more urban areas, a gardener is limited in the amount of space that they have. If you find that you are running out of room, or if you want an outdoor living space, then things may be looking up for you, literally. You may want to consider creating a rooftop garden. Rooftop gardens are an ideal way for an urban gardener to expand their space. Rooftop gardens also make good use of frequently unused and wasted space.
There are, however, a few things to keep in mind when creating a rooftop garden.
How to Make a Rooftop Garden
First of all, find out how local ordinances, rental property rules or home owner association regulations view a rooftop garden. Rooftop gardens may be prohibited or require special treatment andit is always best to know these things before you spend time and money.
Second, get an architect or contractor involved as soon as possible. You don’t need the architect or contractor for the whole garden building process, but you will need them to tell you if the building is safe to build a rooftop garden on. Some buildings were simply not designed to withstand the additional weight a rooftop garden would add. Other buildings may be able to take the extra weight but may only be able to take a limited amount of weight. An architect or contractor should be able to tell you if this is the case with your building.
Third, even if your building can structurally take the extra weight, the weight of your rooftop garden should play a role into your design. Try to use as little weight as possible. Use plastic, fiberglass or foam planting containers and avoid using pavers. Use lightweight potting soil rather than garden dirt. Use Styrofoam peanuts for drainage rather than rocks or pottery shards.
