In this, National allotments week, Gardeners’ Corner celebrates those little plots across the country giving joy to many as well as a rich harvest of fresh food. Presenter David Maxwell visits the National Trust’s community allotments at Springhill near Moneymore where one grower explains hügelkultur. Helen Mark visits the plots at St Columb’s park in Londonderry and Amy Kelly comes live from Ards allotments which is throwing open its gates for an open day. Also on the programme, Bob Flowerdew on “bodging”; putting everything and anything to use in the garden or on the allotment. All that and experts Ann Fitzsimmons and Ciaran Mulholland will join David to take on listeners’ gardening questions. Email – gardenerscorner@bbc.co.uk
