Indeed the BBC made a five hour documentary series “Diarmuid’s Big Adventure” following Diarmuid building a garden there which is subsequently developed an audience for his work in many foreign territories.

He has since worked for all the main broadcasters on both radio and television in the UK and Ireland. For 8 years his main programme, “Homefront”, broadcast by the BBC achieved top ratings.

This series won Diarmuid the Irish Film and Television Award for Best Documentary Series.
A series that was aired in 2009 to great acclaim was Blood of the Irish – which has since won an IFTA - where he travelled the world, determining through genetics, the origins of the Irish race, going back 60,000 years.
