View Here : Why Not Put Community Garden On Roof Of
Burn a light in the garden at night and they will show up to eat the insects and bugs attracted by that light. Provide toads with a cool, dark place and they will stick around for years, helping to keep your garden insect-free. Put up bird houses and the birds will build nests there and help to keep your garden free of bugs and insects.
In addition, the absence of easy access bars the rooftop garden from some members of the community. For this reason the Trent University roof was rejected as a possible community garden site (Dance 2001). After the roof's installation it was left largely to weeds, despite the best efforts of the university grounds crew.
