In this episode, there is a focus on productive gardening in small spaces. Carole is in the 6x8 greenhouse to check the progress of the range of tomatoes chosen because they would grow well in the small spaces. Meanwhile, Calum is on his own Beechgrove plot as he reviews how things are coming along in his square-foot garden, a raised bed divided into sections in order to maximise the use of space and grow a range of crops. George Anderson is on his allotment in Joppa, where he is planting out his pumpkins, and there is a visit to an amateur gardener who has been inspired by her volunteer work at Cowden Japanese Garden.
