Excellent work, simple, didactic, and especially that effectively solve problems in the garden without impacting the environment or health. We think of our grandparents who knew so the herb garden used primarily to heal without making us sick. He also knew that the simple gestures accompanied by little means sufficient to fight against the inconvenience to the garden. Thank you to authors for this homecoming with outstanding photographs and a text that never loses the layman. A buy without asking too many questions.
