The most popular gardening event of the year comes to the National Exhibition Centre in Birmingham. Toby Buckland, Carol Klein, Joe Swift and Alys Fowler will be meeting viewers in the award-winning Interactive Plant Swap. Visitors can bring their spare plants for the new Gardeners' World garden, Greenacre, and in return receive a Gardener's Delight tomato plant as we aim to get the nation growing their own as part of the BBC Dig In campaign. There will be a taste of Greenacre with a reconstruction of Toby's potting shed coming to Gardeners' World Live. This is a unique opportunity to get the public up close and personal with a flavour of the new Gardeners' World garden. Joe will be exploring the wealth of show gardens, while Carol will be in her element in the RHS Floral Marquee predicting 2009's must-have plants and combinations. Meanwhile, Alys will have her thrifty garden head on as she shows how to create instant impact for your garden. And Toby will be demonstrating his 30 minute fix concept live to prove that there are gardening jobs that can be done if you just have half an hour to spare.
