It's the holiday season and there's no better time for Gardeners' World to take to the road, so when Toby Buckland and Carol Klein heard about a community of gardeners in the Ribble Valley in Lancashire with some of the commonest garden problems, they didn't need asking twice to head out and see if there was anything they could do to help. Toby concentrates on the gardens and allotments. Carol gives advice on issues ranging from propagation to pruning.
