Plant Britain is all about encouraging community gardens and planting wildflowers in a two-year initiative to help combat climate change, help wildlife and pollinators and transform our own wellbeing. Matt Baker and Margherita Taylor help Bristol locals to create a community garden, and Charlotte Smith visits a project in Glasgow that is blooming. Sean Fletcher is in Northern Ireland with primary school children to find out about their field-to-fork project. Helen Skelton is with a young botanist who is on a mission to save our native wildflowers, while Joe Crowley discovers the secret life hidden in a special meadow in north Wales. The Natural History Museum do some cutting-edge soil and pond DNA forensics, and John Craven finds out how to do your bit no matter how small a space you have - from a pot on a windowsill to a balcony planter. Also, look out for special messages from some well-known faces.
