Garden Organic, formerly known as the Henry Doubleday Research Association (HDRA), is a UK organic growing charity dedicated to researching and promoting organic gardening, farming and food. The charity maintains the Heritage Seed Library to preserve vegetable seeds from heritage cultivars and make them available to growers.
The Henry Doubleday Research Association (HDRA) was founded in 1954 to research and promote organic gardening, farming, and food. The charity adopted the working name "Garden Organic" in 2005 and is now the UK’s leading organic growing charity. "Henry Doubleday Research Association" remains the legal name the charity is registered and trading.
It was founded by horticulturist and freelance journalist Lawrence D Hills and named after Henry Doubleday, an Essex-based Quaker smallholder who had a particular interest in the properties of comfrey.
The organisation was first based at Bocking near Braintree, Essex hence the name of Bocking 14, a variety of comfrey bred by Hills for its useful properties. A sister organisation was also formed in Australia, the Henry Doubleday Research Association of Australia Inc.
Jackie and Alan Gear took over management of the charity in 1976, and in 1985 the organisation relocated to its present 22-acre (89,000 m2) headquarters site at Ryton-on-Dunsmore near Coventry in the West Midlands. The Gears retired in 2004, when Dr. Susan Kay-Williams became the chief executive and the charity changed its working name to Garden Organic. Dr. Kay-Williams left in the summer of 2007 and the charity appointed Myles Bremner, former Director of Fundraising at children’s charity, NCH.
In 2008, the organisation celebrated 50 years at the forefront of the organic horticulture movement and to this day has over 40,000 supporters. It has trained over 600 Master Composter volunteers from around the UK to spread the home composting message and runs major research and international development programmes that help commercial growers across the UK and overseas adopt organic methods.
In 2010 with funding from the Big Lottery Fund’s Local Food Scheme, Sheepdrove Trust and local authorities in four areas: Warwickshire, North London, South London and Norfolk the Charity set up an innovative Master Gardener Programme. The Charity's Master Gardeners Programme trains and supports mentors and community growing initiatives around the Country working with Local Authorities, Housing Associations and NHS Health providers to support networks of Master Gardeners and volunteers. The Programme has expanded to other areas in the UK and is currently working with G4S in supporting a Master Gardener Programme for offenders in prisons HMP Rye Hill and Onsley.
It actively campaigns on issues vital to both people and the environment including health, sustainability, and climate change, and helps children in over 15% of the UK's schools learn about food and organic growing through its free education programme, Garden Organic for Schools and through its work on the Food for Life Partnership.
The charity's headquarters are based at its Garden Organic Ryton site in Warwickshire. Here the organisation not only leads its charitable delivery activities, but also runs over 30 individual gardens in 10 acres (40,000 m2) of beautifully landscaped grounds open to the public.
As well as boasting the world’s first public biodynamic garden, the site is also home to the Vegetable Kingdom, extensive conference facilities, an award-winning organic shop and cafe and the charity’s renowned Heritage Seed Library, which conserves over 800 endangered varieties of rare vegetable seeds under threat from extinction.
Audley End is a Jacobean stately home owned by English Heritage and in 1999 Garden Organic painstakingly restored its walled kitchen garden from an overgrown, semiderelict state using organic methods. The Gardens continue to be managed by English Heritge under the guidance of Garden Organic.
A demonstration garden in Yalding, Kent, showing organic growing techniques in fourteen individual gardens was closed in 2007 after 12 years' development because of financial unviability, but reopened in 2008 under the ownership of Maro Foods.

The charity relies on funds from its supporters and members to carry out its work and, in return, offers a quarterly magazine, members only web pages and information sheets, as well as access to the charity’s dedicated team of advisors who answer more than 5,000 organic gardening queries every year.
