While gardeners nationwide are getting their gardens in shape over the Easter bank holiday weekend, so too are Toby Buckland, Joe Swift and Alys Fowler. Each of them is creating a back garden at Greenacre. Meanwhile, Carol Klein is out and about at Tresco Abbey on the Isles of Scilly, exploring the extraordinary and exotic plants that thrive in their microclimate under the care of head gardener, Mike Nelhams.
