Monty Don uncovers how gardens can survive neglect, conflict, climate pressure, and changing times. In this journey through the North and Northern Ireland, he visits ruined castles reborn as gardens, Beatrix Potter’s Hill Top, Belfast’s transformed alleyways, Mount Stewart, Mayfield Park, Scampston, Chatsworth, and more. Along the way, he explores community spaces, historic estates, climate-resilient planting, eccentric competitions, and the deep connection between gardens and place.
