Gardeners' World goes wild for the first week of Springwatch, inviting Simon King along to Berryfields to assess the garden's wildlife credentials. Carol is in our new orchard sowing and planting wildflowers to attract endangered moths and butterflies into the garden. Meanwhile, Joe tends his allotment in Enfield before visiting an award winning allotment site at Stoke on Trent. Plus it's time to roll out the Cosmos plants in this year's Gardeners' World trial, and we take a look at both native and cultivated varieties of Cranesbills, commonly called hardy geraniums.
