Regrowing produce is a fun way to save money, flex your self-sufficiency skills, and learn more about the incredible plants that feed us. In their new book Regrown, U.K.-based authors Paul Anderton and Robin Daly chronicle their entertaining journey trying to cultivate dozens of fruits and veggies, herbs and fungi, in their home kitchens, to varying degrees of success. It turns out that ginger is one kitchen staple that was surprisingly easy for them to cultivate.
