Autumn colour for small gardens, a visit to the Greenmount Garden and homegrown greenhouses

Autumn colour might look spectacular on trees, but if you don't have room for them, Gardeners' Corner has some suggestions for smaller plants that are also stealing the show at this time of year. David visits Maurice Parkinson at Ballyrobert, where autumn interest is always a consideration when choosing plants. Not far from Ballyrobert is CAFRE's Greenmount campus, where students are learning the skills to become great gardeners. David meets some of the current intake and explores recent work in the walled garden with instructor James Ross. Near Portrush, a factory is producing handmade greenhouses and orangeries that are shipped around the world. These luxury structures were the brainchild of Mervyn Montgomery, who started the business many years ago after being made redundant from his job in joinery. Anna Hudson also joins David in the studio to answer gardening questions. Contact the programme on gardenerscorner@bbc.co.uk.
