|Mustard Greens and Parsley Growing on the Green Roof Food Patch|
Growing food on a roof is different than growing the food in the ground level garden. First of all the rooftop food garden's visitors are more visible. Pollinators and insects visit the flowers by the hundreds as the vegetables bloom.
Our rooftop garden seems to grow best during the cool and rainy seasons. However, hot weather veggies also do well but their photosynthetic processes move into such high speed during the long hot days with long sun exposure that they must be harvested regularly. Okra for instance, grows extremely fast and must be picked daily or the pods become too long and tough (stringy).
Think of the summer growing season on a roof as a garden in fast forward mode because of the generally unimpeded access to the suns rays for the Calvin cycle sugar production. Think of the summer rooftop garden as your own home-based oxygen generator and carbon sequestration unit.
Think of rooftop gardens as a way to feed the Urban Core.
