A couple in Worthing want a family garden for their young son who has Down's syndrome. Monty pitches in with clearing the site before leading an expedition to RHS Garden Wisley in Surrey where the family learn about different types of sensory plant. In the town of Hitchin, Hertfordshire, Monty offers advice to Aletheia who wants to create a community garden for her neighbourhood. They take a trip to Cranbrook Community Garden in London to see how the scheme might work.
