Diarmuid Gavin

By the end of 2019, Gavin has participated in the Royal Horticultural Society's Chelsea Flower Show nine times, seven on the main avenue, the last having been 2016. His first Chelsea garden, in 1995, was inspired by the coastal gardens of Noelle Campbell-Sharp at Canuig House in Ballinskelligs, County Kerry. He discussed some of his garden concepts, and material sourcing, in his autobiographical volume. He entered again in 1996.

Gavin has been a patron at Southport Flower Show and many others. He became patron of the Royal Horticultural Society of Ireland in August, 2019.

He has run several fundraising events for the Cill Rialaig Artists’ Retreat.

In 2018, Dunnes Stores, Ireland's largest retail operator, announced an arrangement with Gavin, to launch events and special retail facilities on George's Street in Dublin, later expanding.

In 2018, Gavin judged the Young Landscapers Award at the BBC Gardeners’ World Live show.

As of 2016, Gavin was offering a garden design service with Harrods of London.

Gavin presented an episode of Great British Garden Revival on BBC Two in 2014.

In January 2013, Gavin was a participant in the first series of Splash!. Gavin was the fourth celebrity to be eliminated from the show, despite low scores on his first night.

On 8 October 2013, Gavin appeared as a guest on The Sarah Millican Television Programme on BBC, and on 9 October 2013, on the ITV game show Big Star's Little Star, with his daughter Eppie. On 14 December 2013, Gavin appeared on The Chase: Celebrity Special, and on 5 March 2014, he appeared in an episode of Sport Relief's Top Dog with his dog, Roxie.

Gavin participated again in Chelsea, on the main avenue, in 2012, 2013 and 2016. His 2016 garden, the British Eccentric's Garden, inspired by Heath Robinson and others, sponsored by Harrods, and planted with help from Helen Dillon and Carmel Duignan, won a silver gilt medal. He described the complexity of the preparation of the garden, which combined classic garden elements, buildings and mechanical animation, and involved planning and preparation over a year, and around 150 people. He did not participate in the 2017 Chelsea Flower Show, nor those of 2018 and 2019.

In May 2011 Gavin returned to Chelsea after a three-year gap, with his "Irish Sky Garden", which attracted funding of more than €1.7 million from Fáilte Ireland, the Irish tourism body, and was also supported by Cork City Council. Gavin described the garden as inspired by the Oscar-winning animator Richie Baneham (who drove visual effects for Avatar), as well as by the "suspended table" novelty restaurant concept, and by the Midsummer Festival of the Senses at Cork, the landscapes of Capability Brown, Charles Jencks and the some Italian Renaissance figures. The garden was built in an ovoid container suspended more than 25 metres above the ground. 25 reflecting and flowing pools on the ground showcased the garden, which could be visited by show-goers in groups of up to 8. This garden won the gold medal at the show.

RTÉ screened the television show I Want a Garden. In 2011, RTE launched Dirty Old Towns with Gavin as co-presenter, and a second series aired in 2012.

In autumn 2004, Gavin participated in BBC One's Strictly Come Dancing and in summer 2006, Only Fools on Horses. In 2010, Gavin took part in the first series of the ITV reality competition 71 Degrees North and was the third celebrity to become eliminated on 21 September 2010.

On 12 December 2010, Gavin appeared on Channel 4 on a Christmas edition of Come Dine with Me with David Gest, Hannah Waterman and Sherrie Hewson.

Gavin also released an autobiographical volume, "How the Boy Next Door Turned Out: An Autobiography," in 2010.

In 2007, Gavin received an Honorary Degree of Doctor of Art from Nottingham Trent University in recognition of his international reputation for contemporary garden designs.

Gavin runs his own garden and landscape design business, with an office in London, and contact details in Ireland also. The enterprise launched its website in 2005, but after a refresh, the site has displayed a holding page since 2013. Gavin has designed many gardens in the UK and Ireland, and beyond, for commercial, public sector and private clients. In interviews he has mentioned projects primarily in the UK and China, that his work primarily involves travel, and that he has never yet been to Ireland's national flower show, Bloom. In particular the projects in China have tended to be large-scale and of long duration, involving a lot of time away from home, and limiting his work in Ireland and the UK.

Gavin presented Surprise Gardeners, a Central TV (ITV) series, and also Virgin Gardeners for Channel 5. He presented or co-presented a number of BBC television programmes, including Gardeners' World and Home Front (Home Front Inside Out, Home Front in the Garden) with Laurence Llewelyn-Bowen, as well as Planet Patio and Art of the Garden (BBC2). In 2004, he presented Diarmuid's Big Adventure, and a Twofour and RHS production, Gardens Through Time. Homefront and Gardens Through Time both had accompanying books published.

Gavin is the author or co-author of 10 gardening and garden design books, released since 2000, some of which have sold very strongly, been released in multiple editions, and been translated to multiple other languages. His works include:

Gavin won a bronze medal in 1995, and a silver-gilt medal in 2004. In 2007, Gavin's Westland Garden, featuring recycled materials, also won a silver-gilt medal.

In addition to the Chelsea Flower Show medals mentioned, Gavin won an RDS Gold Award in 1991 and again in 1993.

Gavin is married to Justine Keane, daughter of Ronan Keane (a former Chief Justice of Ireland) and social columnist and fashion journalist Terry Keane, who separated in the 1990s. The Gavins have a daughter, Eppie, born December 2004.

Gavin started work with small jobs, the first, a suburban house garden featuring gravel and railway sleepers, in 1988, while he was studying at Glasnevin, still intact as of 2016. A notable early commission was for social columnist Terry Keane, a contract during which he also met his future wife.
