Green power: how gardening changes lives behind bars,  top 10 plant diseases and a new order at Wisley (Ep 151: 22 Mar 2019)

This week we meet the staff and inmates at HMP Hull and discover how a prison garden has helped transform lives behind bars. Last year the prison's horticultural achievements won them the coveted Windlesham Trophy, an RHS award for the best prison garden. Meanwhile back at RHS Garden Wisley we meet pathologist Matthew Cromey who shares advice on the top 10 plant diseases reported to our gardening advice service last year. And finally, entomologist Andy Salisbury introduces a new kind of insect that marks the first new 'order' to be found in the UK in over a century.

And following the recent announcement of a forthcoming ban on metaldehyde-based slug pellets, our resident gastropod guru Dr Hayley Jones offers research-based advice on slug and snail control. Plus questions from members on box problems, growing your own dye plants and dealing with blackfly.

This week we lift the lid on the RHS Herbarium, a unique collection of dried plant material from around the world that's used by scientists, researchers and artists. We learn how and why samples are prepared for inclusion – and share the recent discovery of a very special part of the collection: a potato that was brought back from the voyage of HMS Beagle by Charles Darwin.

Plus, plant pathologist Matthew Cromey shares tips with Guy Barter on how gardeners can avoid potato blight and Chris Young gets an insider's view on what visitors can expect at this year's RHS Flower Show Cardiff.

We visit RHS Garden Wisley to discover the new plant propagation facilities and what they mean for the gardeners there. And it's not just plants that the RHS is cultivating: as we look to the next generation of horticulturists there's still time to enter the Young School Gardener of the Year competition. Plus an exploration of our Partner Gardens, more than 200 glorious gardens nationwide (and overseas) that open their gates for free to RHS members at selected times throughout the year; and our advice team troubleshoots a poor courgette harvest and offers suggestions on replacing an overgrown shrub border.
