This is the first in a new series of beautiful picture books from Ruby Tuesday that explore conservation and science themes. In the middle of the city there was a tired, ugly place that made Mr Green feel very sad. . . So begins this uplifting and charming story of the magic that can happen when young people, older people and plants come together. As Mr Green grows his garden in an abandoned, forlorn space in the city, the following themes are explored: How to grow plants, incuding vegetables / Creating places for wildlife / Rebuilding ecosystems / The importance of planting trees / How the soil is a living thing that needs to be nurtured / The importance of encouraging friendships across the generations / Discovering how enjoying nature and being outdoors is good for our mental health.
