Gardeners' Corner

This week David Maxwell finds out how to preserve some of this year’s harvest with HE teacher come obsessive gardener Kerry Connolly. She’s an expert at turning a glut of marrows and tomatoes into sauces and chutneys for the colder months. He also returns to Howth near Dublin to visit another exceptional garden on this Irish Sea peninsula. This time he meets mountain climber Karl Flynn who has created an exceptional exotic garden through a lifetime of weekend gardening. Oliver Shurmann reveals his favourite perennial for September and Anna Hudson joins David in studio to answer questions and provide seasonal inspiration.
