Gardeners' World - 2010/2011 - Episode 19

August is the time to not only enjoy the flowers and fragrance in the garden but also revel in the wildlife that they attract. To increase the numbers of butterflies and their equally beneficial cousins, moths, Toby Buckland comes up with a palette of plants which will both look beautiful in your garden and also provide them with the nectar-rich diet they need. The much maligned moth also comes under the spotlight when Toby, after dark and with the help of an ultraviolet light, a white sheet and a moth expert, discovers the array of moths that visit Greenacre by night. To extend the enjoyment of the garden in the evening for gardeners too, Alys Fowler plants out pots of night-scented flowers that really come into their own at dusk. At Butterfly World in Hertfordshire, Carol Klein meets Ivan Hicks, who has designed and planted the meadows there on a vast scale. She finds out from him which key annual flowers provide food for our native butterflies and how we can plant them to achieve the same effect in our own gardens. Expert vegetable gardener Sarah Wain, from West Dean gardens in Sussex, visits the trial grounds at RHS Wisley and gives us her recommendations for the top performing veg to grow in our gardens and allotments next year.
