The team faces a rather prickly problem in Birmingham. Annie and Andy's garden is more wild to the eye than wildlife-friendly, but it does not take long for Ellie Harrison to see an opportunity to help a British garden favourite, the hedgehog. With Ellie on a crusade to help nocturnal wildlife, garden maestro Chris Beardshaw sets to work on the ambitious task of building a Gothic ruin, the centrepiece of his night garden. It is difficult to rein in his ambition, as Nick Knowles soon discovers. With Chris suggesting they build a canal and Ellie making moth-feeding stations from old socks and treacle, Nick begins to suspect he is the only sane one left! If this was not enough, the family are keen for a garden, complete with vegetable patch, that will allow them to enjoy the good life. Not to be outdone, Ellie hatches a plan for some rare breed chickens. But can you create a formal garden with a veg patch that will attract wildlife?
