The Gardening Advice team gathers together for a bumper question-and-answer session, sorting out enquiries ranging from whether you can grow your own vine leaves, which figs grow best in the UK, using an old hot water tank as a pond, how to get rid of those pesky little compost flies in your houseplants, and more. Plus ideas for last-minute Christmas presents and a look at 2018's changes at RHS Garden Wisley. For more info and useful links see www.rhs.org.uk/podcast
