Against the odds Gardening with the RHS

Hear the incredible story of EK Janaki Ammal, a pioneering scientist who overcame race, class and gender discrimination to become the first female botanist at RHS Garden Wisley. Dr Chris Thorogood of Oxford Botanic Garden shares insight into the weird world of mutualism – plants and animals cooperating in unexpected ways to make the most of tough conditions. Plus the RHS gardening advisors gather to answer questions on roses (can you grow them in shade and can you move them?), a passionflower that refuses to bloom and growing herbs in planters.
