Whatever the weather, Monty Don, Carol Klein and Ann-Marie Powell go to work with a group of enthusiastic amateur gardeners. Carol visits plantaholic retired teacher Diana Harold in Felixtowe. Helped by Diana's two grown-up sons they tackle the new paths and raised beds of the vegetable plot. Ann-Marie returns to Stockport to help young couple Alison Buckley and Mike Woodhall. Together they construct a rustic boardwalk to give access to the bottom end of the muddy garden. Monty is back with Bryony and Martin Jacklin in their three acre Norfolk plot. This week Monty and Bryony turn their attention to the sad looking bog garden. All the plants are dying - is the cause the soil or are ducks to blame?
