Horticultural programme featuring a group of gardening experts. Kathy Clugston and experts Matt Biggs, Christine Walkden and Ashley Edwards answer questions from The Swiss Gardens on the Shuttleworth Estate, Biggleswade. Taking a tour of the gardens, the GQT team attempts to patch up all manner of plant problems. From reviving a lovelorn laburnum to cheering up a sad cistus and investigating why the phyllostachys nigra gives up the ghost after flowering, the panellists offer their tips, tricks and ideas for thriving greenery. Away from the questions, Head Gardener Sissel Dahl shows the team around the gardens' grotto and gravel display, pointing out the plants that are blooming during this early summer season.
