After a cold first week of May, David and his experts guests take calls from listeners on encouraging more worms in the garden, growing great blueberries and a beginners guide to figs. Also on the programme, David chats to Gardeners’ World presenter, Frances Tophill about her allotment and he catches up with Jimi Blake about the year ahead for his celebrated garden in Wicklow. And after a listener got in touch about rusty nails being good for pot plants, David asks about other garden related old wives tales.
