Sue Lawley's castaway this week is the gardener and broadcaster Geoffrey Smith. He learnt his craft at his father's knee growing fruit and vegetables for the stately home where he worked. Later he learnt the science of horticulture at college and achieved top marks. He's always maintained the promise he made to himself as a boy: to spend his life outdoors. Except, of course, when he enters a studio for Radio 4's Gardeners' Question Time.
