Any tips on how I can successfully grow heavy potatoes in a bucket? Is there any way to get rid of slugs without killing them? Do you recommend the use of Coir in compost and how would you use it? Peter Gibbs and his team of horticultural experts are at Trinity College in Oxford for this week's episode of Gardeners' Question Time. Joining Peter to resolve the audience's horticultural dilemmas are passionate plantswoman Christine Walkden, garden designer Chris Beardshaw, and Head of Oxford Botanical Gardens Dr Chris Thorogood. Later in the programme, Chris Beardshaw speaks with head gardener of Trinity College Kate Burtonwood to discuss the potential trials and errors of redesigning their north lawn border.
