Where to start in the garden this spring, Jimi Blake’s new borders and producing trees on an industrial scale

As Spring officially begins, David Maxwell heads to Jimi Blake’s Hunting Brook Garden in the hills of County Wicklow where he has brand new borders in mind. At the National Trust’s Mount Stewart, work begins on a tree nursery that will produce 600,000 trees a year and gardener Archie Parke retires after five decades of service in Belfast’s Botanic Gardens. In studio, Cherry Townsend will take questions and provide some spring inspiration and wildlife Katy Bell on what to look out for in your garden this spring.
