In a special programme, Gardeners' World comes from the RHS Hampton Court Palace Garden Festival. Nick Bailey and Arit Anderson share highlights of the show gardens and floral marquee to inspire us all to get growing! Arit encourages us to think more sustainably as she reveals her entirely peat-free feature garden. Sue Kent takes a wander through the RHS allotments looking for ideas and tips we can all try at home. Rekha Mistry has advice for growing in containers, and we follow RHS gold medal winner Tom Massey as he mentors novice garden designers with big ideas for their pocket planting plots.
