 Hamilton wrote or co-wrote a number of books to accompany his television series (see below).His practical hands-on experience, down-to-earth, cost-saving approach to gardening, his desire to share his failures as well as successes with the audience, combined with a gentle humour were some of the keys to his success and popularity.He was a committed and informed early advocate of the organic approach to gardening, helping to dispel the rather widely held belief that organic gardening was slightly odd and 'cranky.'
