In West London, Alan and his team meet Sybil, a widow who is struggling to keep on top of the garden she used to care for with the help of her husband, Harold. Alan creates an intimate peaceful space with a water feature, soft planting and parasol trees to create a quiet spot for reflection, while Bruce Kenneth builds a bespoke bench for Sybil to sit and remember her husband. Elsewhere, Danny Clarke visits the Barbican, where gardeners have transformed this urban landscape into a haven of greenery.
