In this episode of Gardeners' Corner, David Maxwell visits what some call 'Ireland's secret garden' - Kilmacurragh in County Wicklow. The site became part of the National Botanic Gardens in 1996 and since then a restoration programme has been underway. Leading the tour of the gardens, which boast a vast plant collection, is head gardener Seamus O'Brien.

Seamus is also continuing the work of the Victorian plant hunters. He has gathered plants from Chile, China and Tasmania on his own plant hunting expeditions. Also joining the tour of the gardens is Neil Porteous from Mount Stewart. The two gardens cooperate in the work of creating a 'Noah's Ark' of endangered southern hemisphere plants in the temperate Irish climate.

Join David Maxwell and the gardening gang for a very festive Gardeners’ Corner Christmas special from the National Trust’s Rowallane Gardens in Saintfield, County Down. The team leave behind their dirty denims and don their festive finest for an outdoor gathering around a crackling fire. With mystery seeds in crackers, Secret Santa silliness, and festive food from the garden, all washed down with some seasonal gardening know-how – this is one Christmas Special you won’t want to miss.

With the festive season in full swing, David heads to Montalto Estate in County Down for a winter walk with head gardener Lesley Heron. While Storm Bram has created some extra work, there’s still plenty to enjoy, including plants that bring colour and structure to the darkest months of the year. Also on the programme, David chats to Brendan Gilsenan at the National Botanic Gardens in Dublin about mistletoe — the seasonal plant romantics seek out at this time of year — and Maeve Bell explains why every garden should make room for a mahonia. Back in the studio, David is joined by garden expert Brendan Little, along with Katy Bell for her winter wildlife update. Email the programme at [email protected]

On a very wet week, David visits Mount Stewart to see how storm-felled trees are given a new lease of life in the sunken garden. Urban spaces are reimagined with innovative native meadow cubes and Maurice Parkinson explains why now is a good time to sharpen tools.

Autumn is far from over, as David Maxwell discovers with Maurice Parkinson at Ballyrobert Cottage Garden. A fine collection of maples—perfect for a cold climate and heavy soil—thrives there, putting on quite the autumn spectacle. In Hillsborough, head gardener Claire Woods is preparing pots for tulip bulbs. She explains how to extend the display by choosing varieties timed to follow one another. With its many mature trees, Hillsborough is also the perfect place to learn about making leaf mould—sometimes known as gardeners’ gold. In Dromore, Julietta Watson uses summer strawflowers to craft baubles for Christmas and pots up colourful containers for her windowsills. Also on the programme, Anna Hudson joins David in the studio with seasonal inspiration and answers to listeners’ questions. Email the programme at [email protected]

In this autumn special, Gardeners’ Corner celebrates our relationship with trees. David Maxwell returns to his childhood home to revisit the trees he grew up with. Tree expert Tony Kirkham introduces some of the trees grown in London’s Chelsea Physic garden which may prove more resilient than our natives as the climate changes. The myths and legends linked to trees are something that fascinates storyteller Vicky McFarland – she reveals tales of love and death. In Rostrevor, County Down, former carpenter Paul Clerkin knows the trees of Kilbroney Park better than most. Now a public park, it was once a grand estate where exotic trees were planted as status symbols. Amidst the beauty of the season, the programme also explores how trees continue to help us by cooling our cities, preventing floods and removing pollution. Email the programme at [email protected]
