Growing plants, whether inside or outside, can foster feelings of happiness and bring people together. Community gardener and designer Tayshan Hayden-Smith and writer Alan Heeks discuss the importance of greenery of all kinds. Hayden-Smith’s Small Space Revolution: Planting Seeds of Change in Your Community sets out his blueprint for why we need to green more outdoor spaces and the practical steps we can all take to do so in our home or community. Heeks’ Natural Happiness shows how gardening methods like composting, mulching, and crop rotation can be used to cultivate human nature too. In conversation with Kitty Corrigan, a free-lance journalist with a special interest in rural and environmental issues.
