Garden Carbon Footprints, Wasps in Springtime, and Pruning Shrubby Hydrangeas

This week Guy Barter and RHS Sustainability Fellow Chloe Sutcliffe react to a recent study published in the journal Nature Cities that claims that urban agriculture has a carbon footprint up to 6 times bigger than conventional agriculture – discussing what this means for allotmenteers and community gardeners, and how we should be thinking about our environmental impact. Entomologist and wasp defender Serian Sumner explains why spring is the perfect time to make peace with yellowjackets, as the queens emerge from hibernation. And the RHS’s Adrian Thorne gives us a practical guide to pruning shrubby hydrangeas.  Presenter: Gareth Richards Contributors: Guy Barter, Chloe Sutcliffe, Serian Sumner, Adrian Thorne Contact: [e-mail]  Links: Nature Cities: Comparing the carbon footprints of urban and conventional agriculture Endless Forms by Serian Sumner Shrubby Hydrangeas  The Garden Magazine
