What should I plant on the roof of my houseboat? Should I grow lilies in containers or flowerbeds? What is the worst gardening idea you’ve ever had?

The GQT panellists are back in North Shropshire to answer these questions and more in front of a live audience. Ready to share their insightful advice on all your plant predicaments are landscape architect Bunny Guinness, horticulturist Christine Walkden, and garden designer Matthew Wilson.

Alongside the questions, GQT Assistant Producer Rahnee Prescod chats to London Terrariums founder Emma Sibley about the history and creation of these pocket-sized jar-dens.

Over the years the GQT panellists have shared plenty of knowledge on how to be a green gardener. They look at everything from how to make your driveway more environmentally friendly, to efficiently collecting rainwater at home.

We also hear Hafsah Haferji's "how-to" on companion planting, and head back to RHS Wisley with Matthew Pottage and Environmental Researcher Tijana Blanusa to learn how trees help us with carbon capture.
