In a special programme, Gardeners' World comes from the RHS Hampton Court Palace Garden Festival. Nick Bailey and Rachel de Thame share highlights of the show gardens and floral marquee to inspire us all to get growing! Arit Anderson encourages us to think more sustainably as she reveals her entirely peat-free feature garden. Rekha Mistry has advice for growing veg in small spaces, and we follow RHS gold medal winner Tom Massey as he mentors novice garden designers with big ideas for their pocket planting plots.
