In a special programme which comes from all four of the Royal Horticultural Society gardens, the Gardeners' World team are out on the road exploring how each location's differing climate affects the plants they grow and getting plenty of gardening tips along the way.
Carol Klein introduces the programme from Wisley in Surrey, one of the country's southern 'hot spots'. She finds out how plants are assessed in their trial beds and how that information is useful to all gardeners. Carol talks Colin Crosbie, Curatort about the AGM new border and refer to Penstemon 'Hewell Pink Bedder', Geranium Rozanne,Cranesbill, Campanula lactiflora 'Pritchard's Variety,' Milky bellflower, and Hydrangea paniculata 'Silver Dollar'.
In the northernmost garden at Harlow Carr in Yorkshire where the winters can be quite harsh, Joe Swift gets plenty of timely propagating tips from Andrew Willocks,Team Leader, Nursery, whilst he propagates Hebe pinquifolia 'Sutherlandii', and Viburnum x bodnantense 'Dawn'.
