Peter Gibbs and his panel are with Incredible Edible in Swindon. Anne Swithinbank, Bob Flowerdew, and Chris Beardshaw are on hand to answer this week’s questions. They offer advice to budding gardeners on how best to grow asparagus, how to get an Echium as tall as a house, and what to do with hops on an allotment. Also, urban organic grower Claire Ratinon and small-space gardener and writer Alice Vincent discuss growing your own edibles in limited spaces.
