When is a seed ready to harvest? Which evergreen shrubs could I plant on the coast? Why are my greenhouse grapes going mouldy?

Kathy Clugston and her panel of horticultural experts are answering questions from an audience of keen gardeners in Kingston upon Hull.

Joining Kathy to plant some useful seeds of advice are proud gardener Matthew Biggs, garden designer Bunny Guinness and head gardener Matthew Pottage. They discuss the best time to use soil improver, how to see a eucalyptus tree through winter and their most creative ideas for attracting punters to open gardens.

Later in the programme, Matt Biggs pays a visit to Stratford Fire Station to hear how they’ve transformed and rejuvenated their garden space.
