What to plant to turn my garden into an oasis? Where do I start with an allotment riddled with weeds? How do I grow saffron? In Hale to answer these questions and more are Peter Gibbs and this week’s GQT panel - plants expert Christine Walkden, self-proclaimed botanical geek James Wong, and Ashley Edwards, Head Gardener of Horatio’s Garden. Also, we return to Horatio’s Garden in Stanmore, West London to find out more about the effect nature has on our mental and physical health.
