Did you know that the Queen’s gardener is using garlic spray on the roses? We didn’t! A guided tour with Alan Titchmarsh in The Queen’s Garden (ITV) was a rare treat and told the story. This show, the first of a two-part documentary, hid another surprise. We’ve always thought Prince Charles was the eco-warrior in the family, keen to abide by organic methods. But it turns out it’s the Queen who is most committed to pesticide-free gardening. She insists that no man-made chemicals are used to spray the roses for greenfly — instead, the bushes are doused in water steeped in garlic.
