S6, E5: Everyone is very excited about the Pontypandy Flower and Vegetable show being held in the Flood’s Garden, to be judged by fireman Sam. Mike is entering a marrow that he’s been growing on his compost heap. But Mike is so busy that he doesn’t heed Sam’s advice about turning over his compost heap regularly to keep it from overheating as it rots. Meanwhile, Elvis is left in charge of Station Officer Steele’s tomato plant with chaotic results. When Mike removes his marrow, the air gets into the heap and starts a fire! Sam and Penny race to the rescue in Jupiter. With the fire out, Sam gets down to judging and Steele gets a very unexpected prize!
