As winter approaches, Helen Mark heads to Drenagh Gardens near Limavady where Conelley McCausland has set about restoring the vast walled garden and extensive grounds which had almost disappeared under the invasion of bamboo. Also on the programme, a visit to Ciaran Mulholland’s garden at the foot of Slemish where he’s growing a ready supply of winter veg. In studio, Reg Maxwell joins Helen to take questions live and Tony Kirkham reveals his tree of the month for November.
