South Africans plant vegetable gardens that are free to use for those in need
Called “sidewalk gardens” residents set up edible plants in their sidewalk garden, tend to them and watch them flourish. The reward will be when the fruits and vegetables are harvested by others. The concept works on the basis of anonymity, meaning the planter and the harvester don’t have to meet as a means to protect the dignity of those needing the food. To start your own public garden, simply prepare a space on your property that is accessible to the public and make a clear sign saying the produce is free for the taking. Make sure to plant seasonal fruits and vegetables, as well as water wise plants for those living in areas with water restrictions.
There is even a Facebook group to get and give advice: https://www.facebook.com/groups/282066233085016/
