Autumn

The year is drawing to a close as a glorious summer gives way to autumn and Kew Gardens embraces its new colour palette. On Cherry Walk, 6,000 tulip bulbs are being planted for spring flowering and Tony encourages the team before visiting the arboretum to investigate why some of his trees are showing signs of seasonal shock. In the kitchen garden, Helena is planting onions in the autumn in a bid to avoid an onion-munching bug. She shows off some potato substitutes and pumpkins, while also selling produce to raise seed money.
