Peter Gibbs hosts GQT from the National Space Centre in Leicester. On the intergalactic panel this week are Bob Flowerdew, Bunny Guinness and Matthew Pottage. They answer questions on potato best-practice, looking after an Aspidistra and keeping an Olive tree happy over winter. Also, the panellists offer advice on growing strawberries on an allotment, moving a Hepatica, and perking up an aged and ailing Cherry tree. Throughout the programme, Peter talks to various experts from the UK Space Agency about horticulture away from planet earth, gets his hands on some seeds that have actually been into space and back, and admires the spectacular planetarium ceiling.
