In the aftermath of the Grenfell Tower disaster Tayshan Hayden-Smith brought a traumatised community together through gardening. In almost exactly 5 years his gardening journey has taken him from neglected London street-side spaces to a garden at the RHS Chelsea Flower Show. It's a tale of resilience, resourcefulness and horticultural heroism – and homage to the bravery of 1970s activists whose legacy lives on today. 

There's bravery in admitting your mistakes too, as BBC Gardeners' World presenter Adam Frost shows as he shares one of his gardening fails. Plus, RHS advisors gather to answer queries on daffodils that won't flower, growing lawns in shady spots and veg growing in raised beds.
