Postbag: RHS Urban Gardening Show

What's the difference between anvil secateurs and bypass secateurs? What should I do with well-used compost? If you could design a gardening utopia, what would you include?

Peter Gibbs and his team of horticultural experts have packed up the wellies and travelled to Manchester for the RHS Urban Gardening Show. While exploring the exhibitions, they dig through the GQT inbox to answer your gardening queries. On the panel this week are self-proclaimed botanical geek James Wong, house plants expert Anne Swithinbank, and Curator of RHS Bridgewater Marcus Chilton Jones.

The GQT team are also joined by 'unusual houseplant' specialist Jacob James, 'Cloud Gardener' Jason Williams and landscape designer Conal McGuire, who provide some insightful knowledge on how we can create greener and more eco-friendly spaces in urban environments.
