Carol Klein presents a series following 20 gardeners as they try to have their gardens accepted into the National Gardens Scheme. Gerald's 20-acre plot has a cottage garden, herbaceous borders and a prairie. While spectacular, it has a steep bank that needs good plants. Maggie has created a jungle-themed area in the centre of Brighton, with many plants and structures. Her garden is small, and the lawn is affected by the shade. What is the county organiser going to say and what can Carol do?
