To mark the coronation weekend, this episode celebrates the people who give up their time to help others. Adam visits a walled garden in Somerset to meet a group of volunteers who are gardening alongside those who need help to transform their lives. At Longmeadow, Monty creates two different planting schemes for pots for shady spaces, transplants grasses in the jewel garden, and plants out his favourite varieties of tomatoes. Rachel revels in the superb seasonal displays of azaleas in Shropshire. As peat-based composts for gardeners will be banned in 2024, Arit finds out what’s being done about the peat used in container-grown plants. Plus a husband-and-wife design team who are about to create their first garden at the RHS Chelsea Flower Show, and a gardener with a passion for tulips who loves to create colourful displays. And there are more of the films that have been sent in by viewers.
