With the mild weather set to end in the next few weeks, David turns up the temperature by visiting the new ‘Banana block’ in east Belfast where 4 varieties of bananas are being grown in stylised raised beds which are also an art installation. Claire Hall explains that growing bananas is nothing new in east Belfast, in fact it was first done over a century ago. Also on the programme, Reg Maxwell is planting spring bulbs in pots and on a visit to Kilcoan gardens in Islandmagee, David finds Cherry Townsend taking root cuttings. Claire Woods and Ciaran Mulholland will join David live to take questions including what to do with an exotic tree fern as autumn gives way to winter. gardenerscorner@bbc.co.uk
