Kathy Clugston is joined by Matthew Wilson, Pippa Greenwood and James Wong from the comfort of their own homes, answering horticultural questions sent in by the audience. This week the panel tackles questions on how to grow seeds in an old grow bag if you don't have access to a garden, and ideas to get teenagers outside and involved in gardening. They also recommend ways to make your last remaining supply of compost go far, and advise on office plants that may not be seeing so much water these days. Away from the questions, Matt Biggs tells the story of the Dig for Victory campaign in the Second World War, and Chris Beardshaw gives us his gardening glossary.
