Eric Robson and the team are in the Horsham District, West Sussex. Matt Biggs, Pippa Greenwood and Bob Flowerdew are on hand to answer the questions from keen gardeners. This week, they discuss using seaweed as a mulch, what to plant in a large pot, and how to deal with large quantities of compost. They also help gardeners with saving plants from vine weevils and dealing with damage to a tree from hornets, and consider what flowers they would visualise after a yoga class. James Wong heads to Kew Gardens in London to speak to Orchid expert Bala Kompalli and finds out more about this exotic plant family which has over 28,000 species.
