In this week's Gardeners' World, Monty Don shows how to get the best from tomatoes planted in grow bags, demonstrates how to divide agapanthus, and we catch up on developments in the recently revamped dry garden.

Adam Frost shares the progress at his new plot and tackles planting in a shady border against a north-facing wall. Frances Tophill meets a couple in Worcestershire who've created a garden inspired by their travels around the world.

We visit an allotmenteer in Lancashire who has a productive and bountiful harvest of vegetables all year round. In Cornwall, we meet a window cleaner on a mission to champion trees, and more Gardeners' World viewers share the joy that gardening brings them.

The team head to Birmingham for one of the highlights of the horticultural calendar - the annual Gardeners' World Live event.

Monty Don, Arit Anderson, Nick Bailey, Adam Frost and Rachel de Thame inspire us with the best design tips from the show gardens and explore the wealth of plants on offer in the floral marquee. We catch up with Frances Tophill, who has designed and created her very first show garden, and we also meet expert growers who share their passion for penstemons and hydrangea.
