Episode 28

As the leaves drop and the flowers fade in our gardens, we turn our attention to the winter months ahead. Toby Buckland, refusing to be beaten by the cold, has ideas of crops to plant now to really eke out the veg patch over the winter months. He is also cashing in on autumn being the perfect time to plant fruit by bulking up the garden with a variety evocative of warm, sunny holiday destinations - grapes.

Evergreens can add welcome winter colour and structure in a garden any size when other interest has all but disappeared. With this in mind, Joe Swift visits the formal, Italianate gardens at Iford Manor in Wiltshire in search of inspiration for evergreen planting at Greenacre.

Carol Klein is drawn to the warmth of the glass houses at Kew as she delves into the exotic, rich and truly cosmopolitan orchid family, and Toby's nail-biting wait is over; it is the day of reckoning as he heaves his giant pumpkin to a competition in Southampton to find out how it weighs up against the best of the very best.
