No drought warnings are expected in Wales this summer, according to Dwr Cymru Welsh Water but there's still a need for us to be careful with our water usage. We meet growers from the Wales Seed hub, growing local seeds for resilience. How Wales is home to a number of rare plants but some are under threat - we visit the Rare British Plants Nursery in Builth Wells and hear about efforts to conserve them. And in it's 100 anniversary year the British Bryological Society invites you to celebrate with a photography competition ....of Bryophytes!
