Gardeners' Corner

With autumn colour all around, David visits the dazzling collection of rare and exotic trees in the arboretum at Castlewellan Forest Park. Head gardener Alwyn Sinnamon picks out some of his highlights, including a slow-growing tree that could become a family heirloom. Nearby, Marc Johansen is considering the future of the tree collection, propagating new plants from seeds and cuttings, while Aidan Murphy is putting autumn prunings to good use by creating a dead hedge. Despite the sunny summer, Mollie Cunningham's pears haven't ripened on the tree, but she knows how to turn them into a tasty treat in just minutes. David visits her at Ballytrim for sweet and savoury ideas to ensure the fruit doesn't go to waste. Also on the programme, Ann FitzSimons joins David in the studio to answer listeners' questions, including one from two Year 7 pupils puzzled by their strangely shaped carrots.

With autumn colour all around, David heads to an artist's garden in County Wicklow. TJ Maher has spent decades creating Patthana with his partner Simon. With an artist's eye, TJ paints with plants and particularly loves the rich, warm colours of autumn. As they explore the garden, David gets a masterclass in combining colours and discovers how they can influence the way we feel. Also on the programme, Barrie Quinn tells the story of Portnoo Market Garden, while Rosie Maye joins David in the studio to answer listeners' questions and explain why now is the perfect time to make leafmould and compost.

As autumn arrives, David heads to two very different gardens in County Donegal. His first stop is Cluain na dTor in Falcarragh, where expert plantsman Seamus O’Donnell has created an exotic garden full of hidden treasures, just a few hundred metres from the wild Atlantic Ocean. David discovers an Ethiopian banana plant and learns about the importance of slow gardening.
Further north, herb expert Columbia Hillen tends Anamcara Healing Herb Garden, where native and exotic plants thrive on a hillside with dramatic views. The former journalist explains how her upbringing in Romania taught her to appreciate the healing properties of the plants growing beneath our feet.
Also on the programme, Adam Frost chooses Crocus goulimyi as his bulb of the month, Katy Bell joins David in the studio with her autumn wildlife update, and gardener Claire McNally answers questions from listeners.
