Lawrence D. Hills (1911-1991) was a British horticulturalist, journalist, and writer who founded the Henry Doubleday Research Association (HDRA), now known as Garden Organic. Hills' research into the Russian Comfrey plant introduced him to Doubleday's work in this field, work which Hills built upon and furthered. Gardening correspondent of the Observer for eight years, Hills' books included Fertility Without Fertilisers, Down to Earth Gardening, and Organic Gardening, but he was best known for Grow Your Own Fruit and Vegetables, which became a canonical text for gardeners and commercial organic growers.
