Fast-growing options to hide a retaining wall

What trees are flood and arid proof that will still be here in a hundred years? How can I rejuvenate my gappy Heathers? What fast growing plants could we plant to hide a wall?

Peter Gibbs and a proud panel of gardening experts venture to the Whitworth Institute in Darley Dale where they field questions from an eager live audience of gardeners. Tackling everything from hangry heathers to planting dilemmas, the panel includes head gardeners’ Bethan Collerton and Marcus Chilton Jones, and garden designer Bunny Guinness

Later in the programme, James Wong provides  some practical advice on how to keep your plants happy indoors this season.
