Ms Tan, 29, an urban farmer who has started growing microgreens along her corridor is part of a young community finding itself. She is not only growing Kale or Chinese Bok Choy but has also started searching her neighbourhood for useful materials that can go into a small compost bin, and collecting coffee grounds to add to her soil. She is beginning to find herself talking with neighbours too —-  the auntie staying two floors below has been growing herbs for years and they suddenly have something in common to do and talk about. As Ms Tan begins to pay more attention to her plants, she realises that their leaves are starting to wilt after some time. Her new friends in the urban farming circles tell her she needs to replenish her soil, and they give her a long list of recommendations — for mostly purchasable material — but she does not know how to choose what works for her corridor garden. She also knows some neighbours empty their pots and buy new soil when their plants start wilting. The more she delves into her garden and soil, the more she realises how rich soil is, and how the soil on the roadside and outside her block is simply not rich enough for her plants.
