Monty is in the Lime Walk. Last week, as part of the revamp and simplification of the planting in the Lime Walk, he moved the white cyclamen from there to the White Garden and left the pink cyclamen, to which he added more. His plan is to plant a simple strip of plants along the narrow path that will thrive in what has now become a shady and dry set of beds. Monty advised that if you're planting cyclamen outside, the best one is hederifolium cyclamen coum. The pulmonaria is also in the Lime Walk which Monty lifts and takes into the potting shed to propagate. He divides the plant and pots them up and leaves them in the cold frame where they will stay for about 6 months. Carol explained the myth and magic of the sorbus tree in the wild at Tegg's Nose Country Park in Cheshire, before exploring a stellar array of rowans from around the world at Jodrell Bank Discovery Centre, also in Cheshire which is part of the University of Manchester. Here they hold the national collection of sorbus, where they have over 100 trees. Carol met Becky Burns, Head of Gardens and Interpretation who spoke about Sir Bernard Lovell - the leader of the team that built the Jodrell Bank telescope. He was also a keen botanist and was passionate about trees and started his own aboretum in his back garden. Joe met Tim Wilmot who has a suburban oasis packed with tropical plants and found out what it required to create and maintain exotic planting in a most unlikely location - an exposed back garden with heavy clay soil, in Yate, Gloucestershire.
