In the second programme of this three-part series, Sarah Raven takes her mission to halt the rapid decline in Britain's essential bees, butterflies and pollinating insects to our towns, and challenges the RHS Britain in Bloom competition to make their floral displays more nectar- and pollen-rich, to help to increase the amount of food and habitat for pollinating insects throughout the spring and summer months.

Sarah Raven takes her mission to halt the rapid decline in Britain's essential bees, butterflies and pollinating insects to our cities and challenges our city parks departments to sow nectar rich modern meadows, and to make their floral displays more nectar and pollen rich to help to increase the amount of food and habitat for pollinating insects.
