Returning for a second series, Alan Gardner comes to provide some landscape makeovers, with his autistic mind giving him a unique take on shapes, patterns and textures of gardens.
In this opening episode, Gardner helps a couple in Lancashire who need help with their garden, which has an odd triangular plot shape. However, he only has a budget of £10,000.
Gardner also travels abroad in this programme. Tonight he visits a garden in the middle of New York.
The Autistic Gardener is on Channel 4 at 19.00.
