Diarmuid Gavin wants us to rekindle our love for lavender. On his revival, he learns about its popularity and decline when he visits what was once one of the major lavender-growing regions in the UK. He meets a fellow lavender enthusiast and breeder in Kent, who is on a mission to create the ultimate lavender, and he gets a taste for lavender's surprising culinary uses. Diarmuid shares his tips on how to grow the perfect lavender hedge and how to increase lavender stock in your garden by taking cuttings.

Alys Fowler wants to bring back an important part of our gardening heritage - the knot garden. On her revival, she visits Hampton Court Palace to learn about one of the earliest knot gardens created, she helps out with a knot garden community restoration project in the Midlands and meets a man whose knot garden has turned into a real labour of love. Alys shows us how easy it is to create a contemporary take on a knot garden using herbs and other edible plants. Show less
