Robot gardeners, Hidden Huntley and preventing puddles

David explores a secret walled garden close to Belfast where globe artichokes are on the menu. Hidden Huntley is one of the 19th century ‘linen houses’ of Lagan Valley and it’s been home to Antonia Malcolm’s family since the 1920s. But there is trouble in paradise as Box blight has wiped out an important element of the gardens structure. Still, there is more than enough soft fruit to go around and rhubarb is being ‘forced’ – David finds out what difference it makes. Also on the programme, a visit to Ciaran Mulholland’s garden at the foot of Slemish where he’s dividing snowdrops ‘in the green’, work continues at Glenarm on the new woodland garden and meet the robots that garden.
